p.1 #1 · p.1 #1 · 7D vs. 50D vs. 5DM2 Shootout - all ISO's - JPEG, ACR, DPP Black Frames


Just in case there are any gearheads that nutty/obsessive as I am, I shot a bunch of Black Frames with my 7D and 50D in JPEG (both no and max NR), RAW-ACR, and RAW-DPP at ISO's 100-12800. I boosted six stops in Photoshop and provide full-size crops and actual pixel images in a format that should allow you easily compare not only the different processing methods, but how the 7D compares to the 50D.

I'm still thinking/analyzing this a bit (I appreciate feedback) ... but for those folks who dislike "horizontal banding", you are going to like the 7D - as others have said, the noise is much more random and grainy/film-like - below are full-size's crops at ISO6400 using DPP - guess which one is the 7D and which is the 50D! ;-)

RED means 5D2 or 50D so first one is 7D

What's up with the vertical line straight down the middle of the 7D shot on your site?

Alek, can we iso compare 5D2 and 7D - we already have 5D2 baseline here - just set the DPP the way i did. All shots at 1/100

Update: I've gotten a set of 5DM2 frames and updated the web site with them ...

It would be interesting to compare to a 5D2 ... since I don't have one, can you loan me yours?!? ;-)

Seriously, any chance you (or someone else) can shoot the same 16 images I did (using the exact same settings) and I'll post-process and add to my site so you can do side-by-side comparisons?

I have Photoshop actions so I can work through in a repeatable fashion and fairly efficiently so we have a true apples-to-apples comparison.


So what I need is put any lens on (I used 17-55 EF-S) and set to Manual, F/16, 1/1000s, ISO 100.
Set to max quality RAW+JPEG, and turn Noise Reduction OFF - everything else default.
In a dark room with the lens cap on, shoot at ISO 100, 200, 400, 800, 1600, 3200, 6400, and 12800.
Turn Noise Reduction to MAX and reshoot those same eight frames.

Create a zip file of all of that (will be about 500 MBytes!) and use some sort of decent big file transfer service (Conrad sent me one RAW file using transferbigfiles which worked well - RapidShare SUCKS!)


This would be an interesting comparison!

P.S. Yohan: Nice spot on the vertical line on the 7D - I didn't notice that earlier - note sure what's up with that, but not easily seen on other images.

Again, I don't mind doing - once I have the 5D2 images, it would take an hour or so to process 'em all the same way, even with the Photoshop actions ... but it would be a darn cool comparison.

Shooting the 16 frames is a snap (but really should be done exactly the same way) ... but uploading the 500 MByte zip file would take a bit of time ... but I'd take it from there.

I'm posting rather than replying via PM in case any other 5D2 owners would be interested in doing this.

I like your work. 7D seem to be a great camera. Thanks

it's better to do this with no lens and may as well just use 1/8000th
some lenses do funky little alterations to rated ISOs when detected.

if you dig deep, at the lower ISO the 7D can show MAJOR vertical bands all across the image, worst looking banding i've ever seen.

Can you go into more detail about this comment? What do you mean by dig deep? Have you done the same technique on other cameras, etc. Thanks.

I like how clean it is even at ISO 800, which was my first priority. For wildlife work, I'd rarely go over ISO 800, so having clean image at that ISO is great news and anything else is a bonus. Looks great even at ISO 1600.

Now to wait for the AF feedback in servo mode.

Thanks a lot for your effort!

Hmmm, Adobe Camera Raw 5.5 is not ready for production, but Adobe warned about its beta stage, so that is okay. Jpeg with no noise reduction looks pretty good IMHO - nice to know when one have to use that over raw for sports and action.

You're just being anal there mate.

First, who shoots their DSLR without a lens?

And second, who boost their photos EV by 6 stops in real life? If the vertical banding is only barely visible in the boosted ISO6400 sample, why would you want to "dig deeper"?

Thanks for the compliments guys and glad it's helpful to 'ya - yes Conrad, Christmas came early ... although that's a pretty big deal around here ... ;-)

Good point Stoffer that ACR5.5 is using a Beta Profile and I just made a note of that on the page.
