Sorry, my mistake, it is 1.6 EV more DR than the 5D3, I corrected my post above. They are going to do some noise analysis too I believe.

http://www.fredmiranda​.com/forum/topic/14479​74 (external link)

Canon hasn't really improved the high ISO ceiling much over the past few releases (look at the 5D3, 6D, 1DX and 1DX2). Perhaps they have been fully concentrating on the shadow detail retention and reducing the low signal noise, and there might not be much more they can do at the high end? It has been several years, and we have seen only very gradual improvements at the high ISO.

That being said, if I can get keepers from ISO 25600 or 32000, I am not sure I need much more high ISO for what I shoot. I would love to start working on my NR methods for the 5D4, as soon as somebody provides a few real-life raw files. :)

From the comparison tools I've seen so far, it does look as though there's a small high ISO improvement, so that's good.

The low ISO DR improvement seems ballpark with other reported sources.

Linked from the FM thread is this interesting bit of info (https://www.dpreview.c​om/forums/thread/40472​60?page=2) (external link); essentially there's some musing that the nature of the Dual Pixel raw files may mean that you have an extra stop of data, because it contains the summed pairs of pixels (like a normal image) but also the data from just one of each pair (i.e. half the sum, if each pair of pixels actually contained exactly the same value). Time will tell if that's valid, but it'll be good to see what people may be able to pull from the files.

I do even wonder if it'll be possible to extrapolate further depth information than is actually present, but that's bordering on wild speculation on my part.


Camera, some lenses, too little time, too little talent

in defence of the 1.74 crop of 4K video

That sounds romantic but what happens if you want to film something ultra wide angle? Due to Canon's EF-S mount, you would have to cut out and canabolize the black plastic piece to mount right on the 5D4 in order to use anything UWA from Canon.

I guess this means it wouldn't be a waste of money if I bought third party UWA crop lenses now. I could always use them for video once I upgraded. It would be nice to know if the 6D2 will also have a crop video issue since I still am thinking that would be better for my wallet. The Rokinon 10mm cine lens looks like the best way to get UWA video on the 5D4 right now though.

This has to be the most annoying, cringe worthy review I've watched on the camera..... It's abysmal.

As just a hobbyist, I don't really care about 4K. I wanted the DPAF though for video even though I rarely shoot video. I think everything else on it looks awesome, except the price but whatever, I ordered it.

I didn't even think of that. Sucks you DO have to have mutliple lenses but your right. Didn't even think of that. Like you said the Rokinon 10mm 2.8 would be perfect for for UWA needs. My 15-30 would give me 24mm and that should be plenty wide enough for most needs. At least it won't vignette at all during video with the crop factor.

That sounds sensible.

If a future 6D also did 4K without any pixel binning (like the 1Dx2 and 5D4) then it (like the 1Dx2) would suffer a smaller crop factor in 4K mode if it had less than 30MP.

The DCI 4K resolution used by the 5D4 is 4096 pixels wide. Standard 4K is 3840. The 5D4's horizontal resolution is 6720 pixels, so it's a 6720/4096=1.64x or 6720/3840=1.75x crop, depending on how you look at it. Hence a lower res sensor would suffer a smaller crop factor.

The only issue with the frame grab is it is indeed DCI 4K framing. You have 2160 pixels in height so if you wanted an 8x10 crop and factor the 8 being the 2160 pixels in height that leaves you with 2700 pixels wide and only a 5.8MP jpeg frame from the video. So it's not 8.8 because your cropping the sides down.

BUT I have already printed this sample and 5.8MP into a 8x10 still looks fantastic. My first priority is to test the 8K frame grab from video for my sons baseball. I've pre-ordered and the camera SHOULD ship out on the 8th. I've paid extra for overnight shipping. I should have the camera in my hands on the 9th. My sons FIRST baseball game for this fall season is the following Monday the 12th.

So expect many samples from me one of which is 4K frame grab for batting which I'll be shooting 4K at 1/1000 to 1/2000 and will see how the affect of rolling shutter affects the image.

I have a question: Which will you pick, 5DSR or 5D4?

Too vague. Many people have different priorities. I've made it clear my decision.

sounds like a real hassle, if I'm going to go through all that trouble, I'de seriously look at a 1dxii instead.

this is micro 4/3's territory in image size as part of the sensor, I dont think you'll use it often. Probably only use it when you want to do video but cant shoot or really focal length limited.

depends on price. Equal price, the 5D4, gps, wifi, and low iso give it the win...... however a 2700 dollar 5Dsr vs 3500 5dIV, then much tougher call

That's the decision I am debating as well. I'm still shooting with my MkII and I looked hard at the 5DIII and 6D but neither really offered anything I needed. I very rarely shoot above 6400, have only used the DSLR video 2~3 times so it's a non-factor, almost always manually focus so it boils down to pure IQ up to say ISO6400. I would have switched to the D810 if I didn't have a ton of Canon lenses so I'm sort of stuck with Canon. I looked hard at the 5DS (never got to shoot the R version) but the few times I shot with it, the end results were not really better than my MkII even when printing A3 or A2. The MkIV looks promising but I'm still waiting for some real world samples.


Not sure why, but call me JJ.
I used to hate math but then I realised decimals have a point.

I posted some amateur shots with 5Dsr in another thread at 12.8k iso if you want to have a look?
