Say What? The 5DS, f/11 and Confusing Circles

HTML:
I enjoy reading things that make my head hurt, it usually means I’m learning something. Roger at <a href="http://www.lensrentals.com" target="_blank">LensRentals.com</a> is always good at it, I’m now going to have to pay attention to Alex Cooke at F-Stoppers. He has written a great article about diffraction the how it pertains to the resolution of the upcoming Canon EOS 5DS and EOS 5DS R.</p>
<p>From Alex:</p>
<blockquote><p>On a 5D Mark III, the size of the Airy Disk begins to exceed the size of the circle of confusion just after f/11. This means the 5D Mark III reaches its <strong>diffraction limit</strong> at that point, the point at which diffraction begins to become visible when viewing an image at 100% at a typical viewing distance. This is different from the <strong>diffraction cutoff frequency</strong>, the point at which airy disks completely merge and no amount of stopping down will improve resolution. Think of the space between the diffraction limit and the cutoff frequency as the space of diminishing returns. On the other hand, the 5DS reaches its diffraction limit just before f/8, slightly over a full stop sooner than the 5D Mark III. This might have landscape photographers and those who rely on having a large depth of field worried.</p></blockquote>

LG G4's camera. Answer to our prayers?

My phone is on its last legs, and I have been holding out for a new phone with a "decent" camera. Is LG G4 with f/1.8 lens, full manual control, and some sort of technology for better color reproduction the answer to my wishes?
Obviously the sample photos were taken by a pro and post-processed well, but they do look to have potential..

Telephoto Lenses , Opinion,Thoughts, Tests,Data,Different Brands etc etc

Long post but here it goes

Besides owning different cameras and lenses , enjoying to take wildlife pictures, I also really like data/comparison, maybe just numbers in general!
———
Background information
Some lenses/cameras I owned
Cameras: Canon 650d, 7d, 1dmkiv, sx50 , Nikon : d7000 , d800, V1 ,Sony : Nex 7 , Rx10 , Olympus Em10 , Panasonic Gh4, , Panasonic fz100
Lenses : Canon 70-200 2.8 ISII, 70-200 F4IS, 300 f4 IS, 300 2.8 IS II , 500 F4 IS , Nikon 70-200 VRII, 200-400 VRII , Others : Sigma 50-500 OS / Zeiss 85 1.4 / Some MFT glass

Liked/disliked : All but the sigma 50-500 OS, I like sharpness and it lacked it to my eyes, It was versatile tho’! , Also I did not find the 300 f4 IS stellar…, the nikon 70-200 VRII was not great @ 200 2.8.
Preferred canon lenses (build quality) and body ergonomics.

Considering : 7dII/5d3 as a body, Lenses I am/was looking at (Combination of the following) : Canon 70-300L/100-400II , 300 2.8 IS II , 500f4 IS II, 200-400, Sigma 120-300S/150-600S
Something else to complement a prime/long lens with 5d3/7d : Olympus em1 + 40-150 2.8 ( that lens looks like the most perfect zoom ever built)


Reason for posting Background info?: To show I will try to be somewhat objective and not here trolling one brand or another.

———
Having spent (way to) much time looking at reviews and data, I thought i share some findings/thoughts here.
My apologies if things are not clear or look clumsy, I’m ok with numbers but writing is not something I consider myself decent at:p
Also my Opinion is mixed into this , please do not be offended.
Everyone likes to justify(or try to) their own equipment/choices, everyone has different needs/standards/cravings/goals/subjects etc etc , different budgets(even tho we can all spend that dollar only 1 time).


Please allow me to elaborate my thoughts, first some boring introduction data(I wrote down A lot of data from many different sites, I will just post a few lenses here ):

Perceptual Megapixels , this is what i consider detail lost due to the lens (With a perfect lens on a sensor giving the Perceptual Mpix of that sensor itself)
I think this is the most interesting data around online , because it makes for really easy comparisons if you are after detail,
It doesn’t take into account vignetting , chromatic aberrations , breathing at different distances etc, but for wildlife I am usually looking at how things resolve detail!

DXO mark perceptual Mpix and Measured Transmission
Canon 5dIII
Canon 600 F4 II [20]
Canon 500 F4 II [19]
Canon 400 F4 DO II [ 17 / 5TStop]
Canon 300 F4 IS [7.5]
Canon 400 F2.8 II [21]
Canon 300 F2.8 II [ 22/ 3.2 Tstop]
Sigma 120-300 Sport [ 20(3002.8 )/ 2.8Tstop]
Canon 200-400 [ 19(300f4)/ 4.7 Tstop]
+1.4 [14]
Canon 70-300L [ 15/ ~10@300mm]
Tamron 150-600 [14/~ 6@600 6.3 , 12-14 @ 600 f8]

Canon 7d
Canon 600 F4 II [12]
Canon 500 F4 II [11]
Canon 400 F4 DO II [10 / 5TStop]
Canon 300 F4 IS [5]
Canon 300 f2.8 II [14 /3.2 Tstop]
Canon 400 f2.8 II [12]
Sigma 120-300 Sport [11 /2.9Tstop]
Canon 200-400 [10(300mm)/ 4,7 Tstop]
+1.4 [5.5]
Canon 70-300L [ 8/ ~6@300mm]
Tamron 150-600 [6]
@600mm [3.5]


Now we can also look at Nikon mount , lets compare some lenses on a d810/d7100 respectively.(Results in Mpix again)
Primes :
300 VRII : [32] /[15]
400 VRII : [33] /[17]
500 VR :[22] / [9]
600 VR :[24] / [10]

zooms:
200-400VRII :[22 ~ 15@400mm] / [9, ~8@400mm]
sigma 120-300S :[29]/ [16]
80-400 II :[18 , ~10@400mm] / [9,~6@400mm]


——————
So what to make of this?, If we just look at pure ‘data’ , this is how i look at and compare the data/lenses with different combinations of cameras! (And their Perceptual Megapixels)
-I am thinking for wild life and not thinking for when one can fill the frame!, also when one can fill the frame it all becomes very easy what is the best lens/camera combo for detail
-These comparisons are based on the centre(circle) portion of the image!( r=1/3 )!
-This is based on cropping the image to match FOV!, even though you might be able to out resolve or match other combinations, it says nothing about noise levels)
-No ISO/SS/DOF consideration

A fun exercise:

-A 200-400VRII on a d810(despite having 36mpix) at 300mm will resolve similar detail to a 300 2.8 IS II on a 5d3 [22mpix vs 22mpix!]
-A 200-400VRII on a nikon d7100 will resolve less detail than a canon 200-400 on a 7d , despite having 24vs18mp sensors! [8 vs 10 mpix]

-A Canon 400 2.8 II on a 7d should resolve more detail than a 7d with tamron 150-600 @600 f6.3 [12mpix/(1.5^2)=5.333mpix, vs 3.5Mpix for the tamron]
-A Canon 300 2.8 II on a 5dIII vs Canon 70-300L on a 7d ==> [22/[1.6^2]=8,59 mix for the 5dIII, vs 8mpix[around 6 on max FL] for the 7d, keep in mind this is 2.8 vs 5.6 also!

-A sigma 120-300S on a 7d vs 5dIII with 400 2.8 III, ===> [ 11mpix vs 21/[1.6^2]=8.2 mpix], so we should be able to resolve more detail with the sigma(centre) combo
-A canon 200-400 on a 5dIII compared to a sigma 120-300 on a 7d ===> [19/[1.6^2]=7.4mpix compared to the 11 on 7d, ’
-Sigma 120-300S with d7100 vs Nikon d810 with 200-400 === 16 vs 15/[1.2656]=11.8

We need to give nikon a little credit as well, so lets compare
- A nikon 3002.8 VRII on a d810 to a 400 2.8II on a 5d3 ==== [ 32/[1.333333^2]=18mpix compared to 21mpix for the canon combo!
- A nikon 4002.8 VRII on a d810 to a 600 f4II on a 5d3 ==== [33/1.5^2]= 16.9 mix compared to 20mpix for the canon combo!, quite remarkable
But
-A nikon 600 f4 VR on a d810 compared to the 600f4II on 5d3===[24 vs 20 mpix , that says something about that canon lens!)
-A nikon 500 f4 VR on a d810 compared to the 500f4II on 5d3===[22 vs 19 mpix]
Now lets look at crop bodies
-A nikon 600 f4 VR on a d7100 compared to the 600f4II on 70d===[10 vs 14 mpix , despite 24vs20mpix, the canon combo wins by quite a margin!!!)
-A nikon 500 f4 VR on a d7100 compared to the 500f4II on 70d===[9 vs 13 mpix]


-Tamron 150-600 on 5d3 (600mm f6.3) vs sigma 120-300S on a d7100 ====[6mpix vs 16/[1.33333^2]=9mpix] , so despite having 600 vs 450(eq) fl, one should still out resolve the tamron by quite a margin!

Maybe some Interesting comparison!, Canon to Canon , Crop to FF!
-Canon 400 2.8 II with a 70d vs Canon 600II on a 5d3 , we have 15mpix vs 20/[1.0666 ] = 17.58 mix, A win for the FF and longest lens, but not by as much as some may expect!(Similar dof, 1 stop iso advantage for crop)
-Canon 300 2.8 II with a 70d vs Canon 400II on 5d3 , we have 17mpix vs 21/[1.3333^2]=11,8mpix , A win for the Crop and shorter lens! (But a DOF difference) (on a 7d it would have been 14 vs 11.8,)
-Sigma 120-300S with a 7d vs Canon 400II on 5d3, we have 11 vs 11.8 mpix , A win for FF and longer lens (Keep in mind this is a 7d and not 70d!)
-Canon 70-300L with a 70d vs Sigma 120-300 on a 5d3 , 7mpix vs 20/[1.6^2]=7.8Mpix , FF combo out resolves, and has 2 stops advantage
————

Some conclusions
- Absolutely nothing can touch the 300 2.8 IS II, it is closely followed by the 400II, 600II, 500II (in that order)
Despite Nikon offering more MP in their Crop and FF bodies(however canon will soon have even more MP, and when matching the 1.5vs1.6 crop factor it’s like 22.98 vs 24mpix)
Nikon super tele lenses are NOT as good in resolving detail , not even the 300 2.8! , the 400 2.8 might be the exception to this ‘rule’, the 500 and 600 are ‘’poor’’ compared to canon super tele
Some numbers to justify this harsh opinion?
-300mm 2.8 : d600[20mpix]/5d3[22mpix] , d7100[15mpix]/70d[17mpix] , despite sensor MP advantage, the canon combo resolves more detail
-600mm f4 : d600[16mpix]/5d3[20mpix], d7100 [10mpix]/70d[14mpix],
-400mm 2.8: d600[21mpix]/5d3[21mpix], d7100 [17mpix]/70d[15mpix], This might be one of the few where it equals or surpasses the canon(this is also the ‘’old’’ 400 2.8VR)


- The Nikon 200-400 seems overpriced considering it’s performance ( I owned this one and was happy with the IQ, but data suggests it is overpriced )
- The Canon 200-400 seems (way) overpriced considering it’s performance (When compared to Primes, or sigma/tamron zoom even…)

Some numbers to support my opinion:
Nikon 200-400 on a d810 [~15mpix, 22max] on a d7100[~8mpix , 9max]
Sigma 120-300 on a d810 [29 mpix ] on a d7100[16 mpix]
Canon 200-400 on a 5d3 [19mpix, 14 with 1.4TC] , 7d[10mpix, 5.5 with 1.4TC]
Sigma 120-300 on a 5d3 [20mpix] 7d[11mpix]

Keep in mind this is f2.8 vs f4 and that it’s a 3000 euro lens compared to a 5600 and 11000 euro lens.
Now the nikon 200-400 is actually comparable to the sigma 120-300 in the corners, sharpness wise(especially at f4), The canon 200-400 is a sharper in the full frame corners, even when both at f4, on a crop on f4 it’s negligible

Why am i stating the 200-400 is overpriced(In my opinion)?,
Because even a 1000$ tamron ( so 10k difference) can match it’s centre performance (with only 1 stop difference)

Canon 5dIII [Mid] [1/3] [2/3] [corner]
200-4001.4 [1835] [1750] [1765] [1775]
Tamron 150-600
f8 [1820] [1740] [1410] [1360]

Canon 7d [Mid] [ 1/3] [2/3] [corner]
200-4001.4 [1265] [1280] [1265] [1270]
Tamron 150-600
f8 [1250] [1215] [1200] [1010]

Furthermore , the 3002.8 and 500f4 are less expensive and perform 'considerably' better
So a 300 2.8+150-600(S), or 500f4+120-300(S), give more versatility with similar or better performance at all focus lengths
—————————
I was thinking about the 200-400 (canon), , but the numbers are against it(when factoring in price)
Honestly I rather have a big Canon or Nikon lens opposed to a Sigma lens…., but sigma as of lately looks compelling
— Fixed the reliability issues the old 120-300OS had, +good weather sealing and fast AF ( not up to canon speed obviously, but customisable and I doubt the difference in tracking will be huge , I need to do more research on this aspect, I found the 300 2.8 IS II with 2xIII extender really fast for initial focus and tracking , but I usually shoot in pretty bright light…..)
- -Allegedly the 150-600 S @6.3 is similar to the Tamron 150-600@ F8 ( I am still hoping we get the 150-600S data soon), but it has better build quality(i.e. weather sealing) , and faster AF.
—The sigma 150-600 compares favourable against the nikon 300 2.8 +2x ( -( http://www.dpreview.com/forums/post/54694447 ), just one example , but looks believable. It looks like it should be close or maybe slightly surpass the canon 300 2.8 IS II with 2xIII, this is just a guess)



For Wildlife
Sigma 120-300S(3000 euros) +Sigma 150-600S (1900 euros) seems a rational decision( when factoring in $$$)

Some possible Downsides: Focus speed?, Tracking speed?, Extreme Corner sharpness, Weight(x2 lenses), Need 2 camera bodies(not everyone likes that)

But what if I really want a white lens :(?:p, Being human, a big white lens is still attractive to own!
Possible combinations:

Canon 500 f4 IS/ISII(4500/8800 euros) + Sigma 120-300S(3000 euros) , Great option compared to a 200-400, but expensive(for 500 IS II)
Canon 300 2.8 IS II(6200 euros)+Sigma 150-600 (1900euros), good alternative
Canon 300 2.8 IS II(1.4/2.0TC 6500) + sigma 120-300 (3000euros), seems odd at first, and a shameful to always have a tc on the canon maybe

‘’budget’’ whites
Canon 300 2.8 L (2200 euros) + sigma 150-600(1900 euros)
Canon 500 4.5L (2500 euros) + sigma 120-300 (3000 euros)
Lack of IS can be quit an issue for stationary subjects.

Some other ‘’random’’ combinations that could be nice

Canon 6d+24-105/70-200F2.8II IS /F4 IS and 7dII with 120-300S/150-600s
Canon 6d+70-200 F4 IS and 7dII with 3002.8 L/IS/ISII or 120-300S, etc etc



It’s a lot of fun to play with numbers and look around at different options, trying to find a combination you can justify in your position(again this is different for almost everyone),
We should take it as it is and not be tempted by all the trolls(From either nikon or canon side), who claim stuff based on a feeling or some ‘real life’ images from impossible to duplicate situations, nor does it really matter ….
Unfortunately they tend to talk the most, so navigating through all the crap and finding some good reviews/opinions/comparisons is hard :(

DXO clearly shows canon lenses>nikon in most cases, yet some canon fanboys are in denial when it comes to DXO sensor testing, Nikon fanboys will claim their superior sensor will make up for their inferior lens(It’s been calculated above that that is not always the case).
It’s all case dependant and also what reviews/data you quote. Personally I do not have any brand affiliation , I like technology , I like advancements, I couldn’t care less who makes them,

In the end all the primes are great/good, some of the more expensive zooms are also good, there are some ‘less’ expensive options out there which perform above what they should do at the price point.
It’s hard for anyone to deny that canon makes the best glass(overall) for telephoto lenses, with the exception that nikon maybe has the 400 and 800 atm ,

It becomes a bit of a jungle once you really get into and look at all the different combinations that will give nice and sharp images !(and there are plenty),
In the end it comes down to taking the actual pictures :), With some luck involved when being there for the ‘’moment’’ , I have some great shots with the d7000 and 50-500 which are not so sharp when looking @ 100%, but I will most likely never encounter lionesses with cubs crossing a river again :( ,

Also something I would clearly distinguish is : Wanting vs Needing,
For me it’s a hobby, it’s all about wanting/liking , I do not need any of it as my living does not depend on it ,


Additional Data

***Note , Normally I look a lot at TDP, but in comparing different brand lenses I think it is NOT a good tool, For an indication between canon lenses it is quite nice(if they are also tested on crop bodies)
—(Only has full frame body crops for all but canon glass, samples different canon lenses (It seems he is putting a lot more effort to get results for canon glass, looking at different 70-200 2.8 samples for example), Different processing in nikon/canon samples)
—( I am not claiming he gets paid or is completely biased towards canon)


Also Other websites/data I looked at : Ephotozine, Camerastuffreviews , Petapixel , Photographylife, Lenstip, Cameralabs

All of them put in great effort , but some contradict each other, I do not know if this is do to lens variations , different testing methods, sometimes different camera bodies etc etc, They seem less reliable.
Also some produce some pretty hard to reach graphs , which weird qualifications which seem a bit random at times and not easily measurable or comparable. Still a lot of useful information on them!, used liked TDP as Indicators.

Thinking of switching out some Lenses, what are your thoughts?

Camera's :40D, 7DMKii, 5Dmkiii

I have Rokinon 14mm 2.8,10-18mm stm, 16-35 f4 IS, 24-105mm, 40mm 2.8 pancake, 100mm 2.8IS, 70-200 IS MKii , 100-400mm mkii(on order) and Tamron 150-600mm and 1.4xIII.

Probably getting rid of: Tamron-150-600 and 70-200 2.8 since I shoot mostly at extreme ends (Landscape and wildlife)
and getting rid of 24-105, and 10-18 to help fund 24-70 mkii.

Thoughts?

<p>Keith at Northlight has been using the a preproduction version of the new printer, and has completed his review of the new 17″ Epson.</p>
<blockquote><p>This printer has been long expected, and perhaps some will be disappointed that it doesn’t make a stronger break with the past. It’s definitely an evolution of the 3880, but I’m inclined to say, a rather good one.</p>
<p>When looking at the SC-P600 earlier this year, and now the P800, I realised that we are at a stage where it’s largely going to be your photographic skill and ability to process/edit files that make the big jumps in how good your prints look. The P800 will show up deficiencies in your photography much more readily than your work will show the printer’s.</p></blockquote>

The Canon EOS 6D Mark II Mentioned [CR1]

HTML:
<p>We’re told that the EOS 6D Mark II will not come until after the EOS 5D Mark IV begins shipping, which will be into the first quarter of 2016. This would follow the same timeline as the EOS 5D Mark III & EOS 6D announcement.</p>
<p>The EOS 6D Mark II will have a slightly smaller and lighter body. It’s suggested we may actually see it use a different battery than the LP-E6/E6n to help with weight reduction. There won’t be any radical changes to the body such as an EVF or articulating LCD. Expect the megapixel count to rise, but not above 24mp. It’s likely the EOS 6D Mark II will have its own sensor just like the original camera.</p>
<p>We’ve received very little about this camera over the last few months, so I suspect the timeline for an announcement is accurate.</p>

Why my camera always sticks to ISO 400 when using external flash in AUTO ISO?

I don't normally use speedlites because I do a lot of school sports and landscape but recently I was shooting family pictures at a family ceremony and I left the ISO in AUTO and later realized that the camera always set the ISO to 400 regardless I was indoor or outdoor or at any different level of ambient light. It resulted in many overexpossed outdoor pictures and many underexpossed indoor pictures. Shouldn't the camera increase or decrease the ISO automatically to match the ambient conditions for overall exposure?
I have tried to find information on the users manual and couldn't find why my camera does that and how to improve this situation. My camera body is 5D Mark III

Support is very appreciated.

ELPH135 help

Will a USB cord be able to charge the camera? The USB cord from my GPS is able to transfer photo into my computer, but can it also charge the camera?

How do I disable the digital zoom function? I notice the digital zoom starts to kick in once I go over 8x, it's getting annoying because I have to keep looking back to the zoom value to make sure I don't go over 8x.

Is there a forum or section on this forum devoted entirely to this ELPH135?

lens decision? 70-200 choices

My son has recently become interested in photography and started to put together his equipment list.
He bought a 5DMkII used but now he wants a telephoto. He asked me to make a recommendation between
a new 70-200 f4.0 L and a used 70-200 f2.8L (not the version II). He looked at the f2.8 and it looks brand
new or at least seldom used and both are priced about the same at $1100. He wants it primarily for youth
soccer games, usually played outside in California sunshine. I advised him to get the new f4.0 because he
didn't need the speed and it was considerably lighter for outdoor non-tripod use. Any comments?

Question, Sir/ Madame--Shoul we take this kind of Photo ?

Dear Teachers and Dear Friends.
So many time that I must take the Street Photos of Homeless, Beggers---ETC, But the more I think, The more I worry , to invade their Private Space that they do not want us to take the shot.
What do you think, Sir/ Madame---We just walk away from that sad moment, and Be Happy in our situation ??
Thank you, Sir/ Madame.

Upgrade from 7D

Hello!

I've been working on a project where I shoot video at 50 fps, mainly at dawn and dusk, for a while. I've now more or less decided that my 7D have too many downsides and would like to shoot the last third of the project with a better camera. I want better picture quality (1080 at 50/60 fps will give this?), better low light capability and want to get rid of the aliasing / moire.

How much is the 7D Mark II improved from 7D in the areas that I need improvement? I've been reading some reviews etc but it's quite hard to get a good overview. I've heard a lot of good things about the Sony A7 and the Panasonic GH4, how do they compare to the 7D Mark II in the areas that matter for my project?

Thanks a lot

Ingemar

760D or 70D

Hello,

I want to kindly ask for help. I am upgrading from 600D, which I broke ::)

I am deciding between 70D and new 760D. For me it is 300 USD prize diffence in favor to the 760D. I shoot fast objects mainly (planes, cars, trains). I shoot other also (like portraits, or landscape), but it is minor. I have 50mm f/1.8 lens and 70-200 f/4 L lens.

I want for the camer to have precise AF for photos as I don´t shoot videos at all. I don´t need Wifi, NFC or other fancy things :) I want mainly IQ, precise AF and long battery life in that prize range :)

I have doubts about 70D since I saw some "issue" threads, but also on 760D, since it is all new and don´t know, what it will be like. I have some time to wait, but I need new camera by the end of the May.

Thank you very much for help :)

Visit Canon.com back in 1996.

This was a cool little resourse to visit websites back in the early internet. Want to see what the press release for the original D30 was? Check it out, and reflect on how much personal digital imaging has changed... Even though I still have a D30.

http://web.archive.org/web/20001007140700/http://www.usa.canon.com/press/051700a.html

If you see an old canon camera you used, link it and we can revel in its antiqued glory.

Local cricket

I tried this for the first time today and found it very challenging. I missed a lot of wickets by chimping the previous delivery. Does anyone have any tips for getting good close-ups with reasonable DOF?

Redrock Micro Solves Focus Control with New Hālo system

HTML:
<iframe src="https://www.youtube.com/embed/5ctFDlPesD8" width="100%" height="390" frameborder="0" allowfullscreen="allowfullscreen"></iframe></p>
<p><em>Video Source: [<a href="http://nofilmschool.com/2015/04/redrock-micros-halo-may-just-change-way-we-think-about-pulling-focus" target="_blank">NoFilmSchool</a>]</em></p>
<p>Redrock Micro Solves Focus Control with New Hālo system</p>
<p>Ability to track and focus on any subject with tap-to-focus ease wins four best of show awards at NAB introductions</p>
<p>Hollywood, CA and Dallas, TX – Redrock Micro, the recognized leader in affordable professional cinema accessories, today announced Hālo, a system for video production that solves the challenge of accurate focus control by dynamically mapping and tracking subjects, and providing an easy to use interface for manually selecting or automatically tracking subjects for focus.</p>
<p>Introduced at NAB 2015, Hālo was quickly recognized for its potential to shift the industry, creating intense buzz and earning three Best of Show awards.</p>
<p><strong>Focus re-designed from the ground up

</strong>Incorporating the same technology cars use for collision detection and avoidance, the Hālo Explorer creates a real-time scene map, combining pinpoint accuracy with up to 180 degrees of view. Artificial intelligence precisely identifies all your subjects (people and objects) and tracks their distance and location in real-time. The beautifully crafted user interface shows birds-eye view of all subjects, and enables anyone to tap-to-focus, or drag to follow focus with visual audible and haptic feedback. Hālo becomes the technician, handling the intricacies of focus so operators can concentrate on the creative performance.</p>
<p>“We often refer to this as our Avatar product,” says James Hurd, Chief Revolutionary at Redrock Micro. “We had to wait five years for technology to catch up so we could deliver a something that solves focus and does it cost-effectively.” This quote references Director James Cameron’s famous quip that he waited 10 years for technology to evolve before he was able to shoot the groundbreaking feature film Avatar.</p>
<p><!--more--></p>
<p><strong>Designed for today’s production environments and creative shots

</strong>Production never has time for long setups, extra gear, or constant tweaking. The Hālo Explorer is small and lightweight, and lives on your camera. There is virtually no setup or configuration, just power on, and you’re ready to go. Hālo also performs brilliantly in a wide range of situations: total darkness or bright light (even heavy backlight), with or without human faces. Hālo components can be moved between the camera and your remote AC, wherever it makes the most sense. A light footprint and wide range of usability use make Hālo intensely practical.</p>
<p>A valuable tool for a crew of one or a crew of one hundred</p>
<p>Productions at any level can benefit from Hālo. High-end productions can use Hālo for precise reference and focus assist. Solo operators can use Hālo for completely autonomous focus tracking. Any amount of assistance or automation is your choice. Whatever your camera and lens, and whatever your level of expertise for focus control, Hālo is incredibly effective, easy to use and understand, and profoundly affordable.</p>
<p><strong>For More Information

</strong>Additional details on Hālo can be found: <a href="www.redrockmicro.com/halo" target="_blank">www.redrockmicro.com/halo</a></p>
<p><strong>Pricing and Availability

</strong>Hālo is expected to be released later in 2015. Pricing has not been finalized but is targeted for in the $2000-$5,000 range depending on options..</p>
