C300mk.ii 15 stop of DR using similar concept as Arri Alexis ? / Dual_iso?

Seems like in absence of exmor type on die AD's, other manufacturers are using something similar in concept to the Dual_iso that ML has. i.e. use 2 different gain paths, one low sensitivity, one high sensitivity, then combining both signals thereby enhancing DR. I was just looking at the Alexis sales brochure and it seems to use a similar idea to get 14+ stops in it's video sensors:

It's a pity the reviewer didn't notice the pretty bad coma (a known problem for the Canon 24mm L) which is a
major problem for astrophotography. Check the gull-shaped stars in this image...

It seem the only option is the Rokinon.

I see your point. I'm actually looking forward to reviewing some of the repackaged Rokinon/Samyang lenses with the auto aperture and focus confirm chips.

The new Tamron 15-30mm is even better.

I meant the 24mm f/1.4 not the 14mm ;) even if the coma is good the tamron would still be a f/2.8 lens

Zeiss Distagon T* 2.8/21mm Review by Dustin Abbott

TWI by Dustin Abbott said:
Zeiss addiction is right. There is just something about holding those beautiful crafted metal lenses that excites the inner geek!

Couldn't agree more. One of the few non-Zeiss lenses I have is the 180 macro, an L-series lens. Compare putting the plastic hood on that vs. the precisely machined metal hood of the 100 mm Makroplanar (or any other ZE lens for that matter, including the 21). Universes apart. +++

Patent: Sigma 400mm f/2.8 OS Sport

9VIII said:
Hasn't it been more than a decade since any third party lenses have been made incompatible?
And even if Canon were to try something like that again, these lenses are all designed with upgradable firmware now.

Its going to happen!!

OOPS, it just did. A whole host of Sigma lenses were incorrectly reverse engineered and have issues on the T6i. Sigma is offering to fix the ones still in production, but any older ones that won't work are just throwaways.

6D or mirrorless

I have a 6D and recently bought a A7. The A7 was returned for a refund, so that is my short answer!

If you have a chance to actually try them in a store, then that would be a good idea as they are very different. If you get the 6D with a 24-105mm kit lens, it is much larger and heavier. That is about the only advantage I found with the A7. The Sony kit lens is pretty bad - quite soft away from the center. Big advantage to Canon. While some Electronic Viewfinders (EVF) are pretty good (the Olympus OM-D, for example) I thought the Sony EVF was a bit dark outdoors. If you like an optical viewfinder, then advantage Canon.

70-300 f/2.8 IS

Not sure I follow. Are you saying only enthusiasts with money to burn would buy it? There would be no interest from pros?

I'm sure they'd sell some if they made a 70-300/2.8, but think about your original question:

Mitch.Conner said:
...what are the chances Canon might replace the 70-200 f/2.8 IS II with a 70-300 f/2.8 IS

You're asking if Canon might drop a very popular $2000 telezoom from their lineup and replace it with a lens that's likely >50% heavier, >25% bigger, and at >$6K at least 3x the cost. As I said the chances are nil.

If you want to know if there a market for a 70-300/2.8, independent from the 70-200/2.8, that's a different question, and one you didn't ask.

My mistake. You're right. I forgot my own original question.

Announcement: Canon EOS C300 Mark II. Full Coverage and Videos Here.

PureClassA said:
Well, Black Magic just released a a whole new firmware for their URSA cameras, which included firmware support a MkII Sensor that hasn't been announced yet. 120FPS in 4K RAW. Who wants to bet we see it tomorrow.... If they fixed their excessive FPN problem with this new sensor, it looks like I'll be looking to buy an URSA down the road. $5995 vs $15995 ....

And unless BM have transformed their lowlight performance you're buying a camera that is only usable in the studio. The C100 looks better at ISO20k than the BM4k does at 1600. And thew C300mkii should be significantly better than the old C100. And that's ignoring every other issue that has plagued every camera BM have released. You might not need a reliable camera, but professionals do.

6k for a studio only camera that might work or 16k for a 15 stops of DR at high ISO in a trusted package. If you had the money - and anyone working with a professional budget outside of a newly graduated one-man production company does - there isn't much of a decision to make.

Video Devices 4K External Recorder

HTML:
<p><iframe width="100%" height="390" src="https://www.youtube.com/embed/2uDNAfU0KHU" frameborder="0" allowfullscreen></iframe></p>
<p><em>Video Source: [<a href="http://www.bhphotovideo.com/explora/video/news/nab-2015-video-devices-pix-e-4k-monitorsrecorders" target="_blank">B&H Photo Video</a>]</em></p>
<p>Sound Devices are makers of great equipment. The have won a number of awards for their innovative products, particularly their audio recorders. However, their external recording monitors were successful enough for Sound Devices to dub the video-oriented division of the company Video Devices.   Earlier this month at NAB—where they won more awards—they showed-off a new series of external recording monitors, the PIX-E series.</p>
<p><!--more--></p>
<p>The PIX-E series is the company’s 4K effort. The series includes three monitors/records: PIX-E5H, PIX-E5, and the PIX-E7. The E5 and E5H both feature a 5″ 1080p screen whereas the E7 has a 7″ 1920 x 1200 screen. The Pix-E5H is HDMI-only. All 3 monitors can record 4K in a variety of Apple ProRes codecs. The E5 and E7 are capable of recording all the way up to ProRes 4444 XQ.</p>
<p>Some features of the monitors:</p>
<p>Waveform Monitor

Vectorscope

Histogram

TapZoom™

Peaking

Zebras

False Color

Frame Markers

Four Way View

LUTs</p>
<p>These monitors record to an mSATA-based SpeedDrive that plugs directly into the monitor using a USB 3.0 connection. This makes it very easy for dumping footage–no more looking for cables or a docking station. They have two versions of the SpeedDrive: a 240 GB version and an enclosure only version which allows you to choose your own mSATA drive.</p>
<p>The PIX-E monitors have a die-cast metal housing and feature a Gorilla Glass 2 screen. They will certainly be as rugged as the Pix-240i, if not more so. The screens on the monitors are in-plane switching (IPS) touchscreens. The touchscreen enables the great feature TapZoom™ to help get critical focus. The IPS panel provides a bright, colour-accurate, and wide viewing angle for your camera team. The monitors are powered by the very common Sony L-series batteries.</p>
<p>Optional accessories that are available include an XLR audio interface and a kit (hard case, articulating arm, batteries, 2 SpeedDrives, sun hood, and cables).</p>
<p>The series is available on <a title="B&H Photo Video" href="http://www.bhphotovideo.com/c/search?Ntt=PIX-E+4K+Recording+Video+Monitors&N=0&InitialSearch=yes&sts=ma&Top+Nav-Search=">B&H Photo Video</a> for pre-order. The 7″ version comes in at $1595, making these the most affordable 4k external recorders. They are expected to be released this summer.</p>

Canon EOS 5D Mark IV Price - Performance?

jdramirez said:
The 5d mkii was revolutionarily better than the mkii. The launch price was $3500. I can't imagine that the price for the mkiv will be less than the mkiii, even though the advances in tech are evolutionary...

I assume the price point will be $4000. If I sell my mkiii @ $2000, then I'm still paying $2000 for a better camera, but how much better. I can't see it being $2000 better, especially since I'm still around 20-30k actuations... So I am assuming there is plenty of life left in the body.

I do get itchy wanting to upgrade, and I have all the lenses I want, save for some great whites, but the mkiv has to be mind blowing for me to upgrade. The mkiii is quite honestly, the prefect camera for me.


The jump from the 5D2 to the 5D3 was pretty large in all areas except for image quality. IQ was evolutionary. But the AF, speed and all else was substantial.

I find it hard to imagine that same kind of leap is made from the 5D3 to the 5D4. I think that is what fuels the 12fps rumor.

I'm with you on the price and upgrade question for owners of the 5D3. I have a 5D3 myself. Selling it would bring about $2K right now. Putting out at least another $1,800 is a lot of money for what is likely to be more mild evolutionary advancements than the previous generation.

It will be wonderful for first time buyers of a serious FF DSLR, but not so enticing for owners of the 5D3.

Nikon Fullframe mirrorless coming?

AvTvM said:
Hmmm .. I see this on the linked NR page:

the camera will be small (about the same size as the Olympus E-M1)

Read more on NikonRumors.com: http://nikonrumors.com/2015/04/20/new-nikon-full-frame-mirrorless-camera-on-the-horizon.aspx/#ixzz3XvKWWddJ
Thank you! Didn't get that.
But as you stated if still with the F mount and no a dedicated mirrorless mount (+adapter for F lenses) there will be no improvements in overall system size and optimized optical design. There the Sony solution is still ahead (in principle, not with the existing lens portfolio).

EOS 5D Mark IV To Use EOS C300 Mark II Technology? [CR2]

But, but, all these friendly folks on the forums insist that more than 12-stops isn't necessary. :o


Kind of like how friendly Nikon folks insisted that more than 12MP wasn't necessary...until the D800 came out.


In all seriousness though, this is exciting. If this camera delivers on DR and video, I may stay with Canon rather than switching to Sony. This is your last stand Canon, make it a good one!

It is funny how excited all those trashing the 'Droners' are the second their is some talk about Canon possibly getting even just a trace more DR than Exmor! ;D ;D ;D ;D ::)

Kind of like how Canon didn't need to produce a camera with 36MP until it had one with 50MP?

Let me summarise the situation with said people:

Any measurement or statistic where Canon has the better number or statistic is important (until Canon is behind) and vital and any measurement or statistic where Canon trails is unimportant (until Canon is in front.)


Oooh, I get it now :)

sigma 120-300 or sigma 150-600 sports

http://www.canonrumors.com/forum/index.php?topic=26037.0

Might be helpful, lots of links and information in there


A quick look at my written down data

100-400L on a 5d3 gives 13Mpix on a 5d3, and ~11 at max FL
120-300S on a 5d3 gives 20Mpis on a 5d3

On a 7d it's ~6mpix and 11 respectively ,

So 120-300S should be a major upgrade, even though you lose some focus length,

Dividing 11 by (1.3333^2), gives us 6.75,

This would mean the 120-300 on a 7D should be able to resolve very similar detail to the 100-400L(version1) on a 7d, despite having 100mm less, you do however have a 2 stop advantage.
---
Even thought it is claimed/proven that the sigma 120-300OS and 120-300S are identical in construction,
Numerous reviews/tests/data shows that the latter is slightly sharper...., Also it is A LOT more reliable, personally i would stay away from the 120-300 OS, and only opt for the sports.

I have not found very reliable data about the 150-600S yet, however indications show it should be similar to your current 100-400
