Sigma Rumors is calling $1099 and $1999 respectively. Find out for sure next week I suppose

gotta see how the AF and panning mode IS perform vs the tamron but If its good i can see myself swapping the tamron for the sport version.

Shooting an event soon -- could use some advice

I just covered my 2nd event in my life. This was a big learning opportunity. And my first time to use a zoom lens on such a scale. I use my 6D and rented EF 24-70 F2.8L II.

On my first event, I learned that I must not be afraid to set higher ISO to prioritize shutter speed. And slowing down is better.

I made a checklist before pressing the shutter. (Camera in Manual mode and Speedlite in ETTL 0 to +2/3)

1. Is subject stationary or moving or approaching
a) if stationary - use back button, shutter speed = > fl
b) if moving - use back button, shutter speed = 160
c) if approaching - use shutter button and switch to AI, and shutter speed = 160, use center point AF
2. Set the composition (choosing focal length) and selecting focus point
3. Check shutter speed > fl
4. Setting Apperture
a) Subject is near - Av > 5.6
b) Subject is medium far - Av > 4
c) Subject is far - Av < 2.8
5. Set IS0 such that metering is between -1 .. 0
6. Focus and take the shot

Most exciting thing at Photokina?

I've been saying, for several years, that sometime soon, a Vogue cover would be shot with a smart phone. The time may finally have arrived :)

Whilst that might well be possible lets be realistic it would still be a gimmick rather than using the best tool for the job.

Would it be a gimmick to a young professional, who grew up using a camera phone. I don't think so, YMMV.

Different generations look at things differently. I think that in a few years the camera-phone generation will look at DSLR users and shake their heads ??? Sorta like a present day DSLR user who sees a Large Format photographer and his back-pack full of film holders.

How much does this cost?

Whatever you can get. Keep in mind that a new one, from major players like B&H or Adorama, will cost about
$3500, and going down monthly. It also depends upon where you are and what the local market is like. Best
way to check is a local Craigslist or even EBay. Assuming mint condition, most buyers would pay$2200 to $2600
for the body and another $600-$650 for the lens. If you have high shutter count or "dings" or scratches it's worth less. If you're lucky, a retailer might consider a close to "even-up" trade for your camera and lens for the 810 body.

Interview hints to future new Canon mount type

Aglet said:
Some allusion to MFT size sensor there, as well, it seems.
When I consider just how good the IQ is from my Oly EM10's tiny sensor, with just enough ability for OOF areas and DoF control, it seems like the 4/3 system was well conceived for all around compromises.
I can landscape at low ISO with some shadow push ability, use iso25600 and get usable images for small prints, put on a long lens for shallow DoF shooting, all in a tiny light package.
Yup, that sensor size is a good compromise.

On the other hand, when Canon finally decides to put both feet in the mirrorless race, the M mount system will yield better IQ than a 4/3 system can. Though Canon seems to have stumbled out of the gate, mirrorless wise, I think we all know that when Canon gets serious, they have the tools and knowledge to produce at least a very competitive camera. Maybe by then they will have improved their sensor/readout components and that, combined with maturing DPAF tech, may allow them to be class-leading in the segment. It's good to dream...

5D MKIII H264 vs RAW vs RAW 3X Crop from Macro 1:1

luciolepri said:
Thank you for your advice, Cgdillan. I don't use Resolve, but I can give your workflow a try.
Usually, I import the DNG to Camera Raw, apply the color correction/grading, export a 14 bit PSD sequence and import everything in Premiere for the video export. But as soon as I convert the PSD into an 8 bit video file, I loose a lot of what I gained shooting RAW instead of H264... that's what bothers me. But I suppose there's no loophole...

I used to do that too but in lightroom. and the export took forever! It was definitely a bit of a learning curve to learn Resolve but I would say it's definitely worth the time because the way it handle 5D raw it beautiful. and the new resolve has some great new tools for raw processing. Also, I always export ProRes HQ from Resolve to retain the best quality for editing.

70D or 7D MK II

MagnumJoe said:
I’m interested in a second body to compliment my 5D MK III. I mostly shoot candids, portraits, my grandson in the park and his T-ball and soccer games. The 5D MK III has done really well and I rented a canon 1.4 III extender and will try out this weekend.

The reason I’m interested in the 70D or 7D MK II for my second body are.
The extra reach and video auto focus.

70D advantages
Touch Screen
Articulated Screen
Price

7D MK II advantages
Ergonomics (similar to 5D MK III)
65 Focus Points
10 FPS
Weather Proof
Headphone Port
Viewfinder coverage, 100%

I’m leaning towards the 7D MK II, but I’d like to hear your feedback and suggestions.

Which one would/will you buy or would you buy?

Hi Magnun,

You said you need a second body? You also have the 6D in your bag.
I would wait and see how different is the performance (particularly noise and ISO) of the new 7D2 over the 70D.
Particularly I'll wait to see real reviews of the 7D2 to see if the premiun over the 70D is worth it.

Hi Hjalmarg1,

I sold my 6D when I bought the 5D MK III, I had plans to buy the GH4, but when I realized the investments i have in canon lens, that just wasn't an option. For example a f/2.8 on the GH4 isn't really 2.8, it's more like a 5.6, so I lost interest.

85mm f/1.2 does street on a 6d.

Dylan777 said:
Hope you have some 3stop ND on hand for outdoor.

Back when I thought I had a deal done for an 85L we had a discussion about shooting the 85L in daylight and how you need a 3 stop nd... and I had one in my cart... for about 6 months until I had the lens in hand. Then I ordered it.

I bought a step down ring a while back because I got it for free, so I picked up a B&W 77mm 3 stop nd... so I can use it on my other lenses if I decide to...

Today when it was sunny I was still getting 1/2500 of a second, so without the nd filter, it would have been 1/20000... which I'm pretty sure exceeds factory specs.

Tomorrow I'm taking my daughter's softball team photos... so I'm hoping for clouds, but I don't think that is going to happen until the games start...

Your add-on request for Canon DSLR's stock firmware

It doesn't exist yet, but if someone really could get the camera to do its own AFMA using DPAF (or whatever) that would be truly great.

I also think they would be smart to put it in every body (or every one that has DPAF ) not just the higher end ones. That would just go to the basic functionality of the camera and the basic image quality, and it would be concealing their own minor manufacturing inconsistency to make every Canon body work perfectly with every lens. Cheaper than trying to accomplish the same thing with massive quality control improvement efforts. And it wouldn't upset the separation of price points between models. The simple one would focus simply but accurately.

Favourites of Photokina: Peak Design

Cali_PH said:
Just did the test, 3 of my 4 springs failed on the slide...not too happy, but glad I found out before I put them on my cameras, unlike the unlucky people that actually had their cameras drop. I hope PD is paying for any repairs necessary.

There were about 50 affected customers at the time when they sent out the advisory, so no additional people should be affected unless they didn't access to their emails.

Patent: Dual Motor For Autofocus on STM Lenses

jrista said:
hoodlum said:
Olympus will introduce tomorrow the first lens with dual VCM for autofocus.

http://www.43rumors.com/precision-camera-discloses-full-olympus-40-150mm-lens-details/

TWO IS BETTER THAN ONE
Smooth, rapid autofocus is a crucial factor in image quality. The 40-150mm f2.8 PRO’s innovative, industry-first Dual VCM (voice coil motor) AF delivers. Separating the focusing mechanism into two lens groups controlled by individual linear drive motors makes AF performance extremely fast and, with no gears involved, nearly friction-free and incredibly quiet.

That is something entirely different than this patent. The motor described here drives the diaphragm to stop down the aperture, which is quite different than the focusing groups in a lens.

Concievably you could use the same preload motor and drive motor design to speed up focus movements, however i dont think the USM motor is the weak link in the focus chain, although i could be wrong.

7D Mark II Video Tested By Gizmodo

Khnnielsen said:
Here is my take on Canon and their video DSLR.

If Canon want to do the smart thing they will bet some money on Cinema EOS line. Where I am from the C300 has been hugely popular among production companies and broadcasters.

The main reason I think is that it bridged gap between the DSLR and the large sensor camcorders. If you have worked with a ENG camera, you know how a camera should feel and work, if you want to an effective tool.
We want to use all our Canon glass with a large sensor, but the DSLR hassle can get tiredsome. The answer have been C300 for the most part.

If think Canon have a good chance to cement their position in this market if they make an effort with the Cinema EOS line.

On the other hand, if the 5d Mark IV is a complete game changer, it might turn out different, but I wouldn't get my hopes up just yet. .

The thing is, the market for video DSLRs and the market for the Cinema EOS cameras are not the same market. They never were. A dude may stretch his wallet to get a 5D to shoot some short films, but there was no way that guy was ever going to pony up $15 grand for a C300.

Literally all Canon had to do to own the micro budget marketplace was to take all of the existing components of a 5D and put them into a more video-centric ergonomic body, and throw in the Magic Lantern video features as software. That's it. That's what people have been begging Canon for these last four or five years. They didn't have to create new sensors or even 4k recording, any of that. But they never built it. Instead they came out with cameras that had most of those features but priced $10k above people's reach, so only actual production companies could afford it.

Now, even if Canon did come out with a Cinema 5D tomorrow, it would be too late. The tech has moved way beyond it, way beyond what even the Cinema EOS line is capable of, and for far less money. There isn't a single thing that the 5D or 7DII can do with video that isn't done better by somebody else, for the same price or less.

That's the bottom line.

This. +1

What I saw was a pop up ad covering the screen. Click bait at its worst.
Sorry about that - it didn't do that to me. I didn't watch the video, just scrolled down through the review.

Interesting video, it really gives an idea of what can be done with a tiny camera in a phone, thanks for the Post.

Picked up my iPhone + yesterday here in Australia, eyes aren't what they were, Phone gets bigger each year, be slapping an iPad to my ear soon.

Canon EOS sensors, and technology

Don Haines said:
Phil Indeblanc said:
I opt for Medium Format because what I shoot demands it. My customers demand it. Life would be MUCH easier if I didn't have to bust out a 4x5/MF dB for a shoot. Work would be much smoother.

Are you using a digital back on your 4X5? If so, which one and do you like it?

Sorry for the long time gap. I haven't been getting email notifications.

I currently use the Phase One P25 often. I also use a H25backup, and have used a Hasselblad CF39, Phase One P45, and a more current IQ180

I'm sorry and understand I sound stubborn about this. It is only because I see this segment getting zero attention from Canon, who I have over $20K into.

On the flip side I DO see SONY, and Nikon address these areas. I also see Pentax 645z in action, and ALL MF dB's in the same common denominator. Even Sigma(As there is no need)...So Canon is alone. It is now so commonly spread, that having no AA as become a marketing tool. When working with difficult subjects like reflective product, and you have ZERO absorption surface. Everything is reflective high polish you can see how big a difference AA vs no AA is.

I think mirrorless is surely the direction, and yes, an in-between mirror space gap can make it much easier. I forget the brand years back, I briefly worked with a camera years back that would take filters on the lens mount.

6D Mark-II in response to the D750

zlatko said:
Chuck Alaimo said:
uggg... where to start. For one, the whole respond respond respond thing is growing quite tiresome. Maybe, just maybe canon has a plan and they are releasing things according to that plan? But, for the sake of playing along...

Exactly! The whole "respond" / "response" / "answer" notion assumes that cameras are like sentences in a conversation and can be tossed into production at a moment's notice.

It's more likely these products are conceived far in advance of any competitor's announcement, with countless planning, production and testing stages leading up to release. Every part has to be designed and produced. Every material has to be sourced. Every employee has to be trained. It goes on and on .... Large companies plan and plan and plan because they have to coordinate and direct a mass of people, machinery and money over long periods of time in order to achieve their goals. They have short-term plans, mid-term plans, and long-term plans.
R&D is continuous.

DSLRs are modular products by design. This gives the manufacturer a lot of leeway to create a variety of products from a smallish pool of common core modules. If the interfaces are already specified then then R&D can be done separately for each module even by different teams or business partners around the world.

Certain interfaces are common in classes of EOS cameras:
Spatial interfaces (e.g. lens mount, flange distance, battery compartment etc.)
Media interfaces (e.g HDMI, SD, CF etc)
Electronic interfaces (e.g. for Sensor, DiG!C, AF, Metering etc.)
etc...

One of the other advantages of modular design is being able to leverage existing modules which have been already been through the R&D/testing mill. This allows them to be bring products to market faster. The better the engineers understand the platform, the more reliably they can connect the modules with minimal QC issues.

It is entirely possible that Canon has already designed and specced three different 6D-II prototypes and are just waiting for the right time to pull the trigger on launching either option A, B or C.

So when I say "respond to..." I don't mean Canon's engineers need to sit around a table this afternoon and design (from scratch) a reply to Nikon's announcement. I also mean the years of work that's been going on behind the scenes developing (Prototype module X) and (Brand new top plate Y) combining with (Wifi module that worked last time) with (good old Tilty-flippy-LCD) and (LP-E6N)....etc
