Ditto to that. Some of these critics should just do their own bloody testing.
I just ordered my demo 1D4 from Vistek in Calgary.
Great choice - I am tempted to 1D4. My observations is that if you look at dxomark, you will find that crop camera don't get the full 60% gain (look at resolution ll/in) - they only get about 1/2. So likely the 1div is only 10% less effective reach than 7d with better BIF focussing and nicer noise. But my focus is on static big animals.

Thanks for posting these. I'm not sure where to look for the most detail so it's a bit tough to make comparisons. Except for the noise, I don't see much difference between them. The last test really isn't fair to the 7D either - the shutter speed is 1/320 instead of 1/125 for the 5D.
Generally, I did this test (along with others (Ajay for example)) and find that the results are pretty close but the 7D wins if focal length limited. I think the 1D IV is probably the best compromise to be honest. You can cover everything well and make up for the lost focal length with the 2x on a 500L. I am hoping the new 500L is as good w/ the 2x as the new 300 and 400. They are very sharp, although there are of course AF considerations.
The 7d with 1.4x was set at 1/320 because it was at F4, whereas 5dIII was at F5.6 (because of 1.4x). You are right that the 1/250 vs 1/125 would have been better but I did the 1.4x quickly and I don't think its a big difference.

Thanks for doing these tests Scott. I had promised to do something of the same but never got around to it. You can never win in these types of tests. There will always be criticisms no matter what you do in your tests.
The question I'm trying to answer is if it is worth it to keep my 7D for focal length limited situations. My gut keeps telling me to let it go and I never seem to want to bring it out and mount it on my 100-400 now that I have the 5D3. I'm fairly happy shooting the 5D2 with my 17-40 or 24-105 and the 5D3 with my 100-400 for the time being. However, I know deep down that when the wildlife is far or too easily scared off that the 7D will still probably net me the best results.
What I really need I guess is longer glass or a 1D4...Show more →
What you really need is a 2nd piece of tele glass so you can mount 7D on one lens, and 5D3 on the other. Find yourself a nice 500/4.5 or so for that 7D. Unless I'm hiking around, I usually take two bodies parked on two lenses (and my little NEX with a wide angle lens or two).

Keep it. The 7d is way cheaper than buying the 600 f4 II. For wildlife reach is everything.
I think in good light, the 7d is better than 5diii. Its rare that you have enough reach. I have the 100-400 70-200 2.8 and 500 f4. I am going to yellowstone at the end of the month and I assure you that I will have 100-400 on 5diii and 500 with 1.4x on 7d, when I drive through the park. And as it gets darker I will switch to 7d on 500 F4 and 5diii on 70-200 2.8.
Yeah, but I actually have the 600f/4 mk2 preordered from your local TheCameraStore. I want big glass!!! Still will probably keep the 7D till the used 1D4 price drops enough to make that switch.

I wish I had "the old" 500F4! I picked up "the ancient" 500/4.5 a few years ago for $3200, its gonna have to last me a while.

I also have a question on the DoF. According to the Dofmaster calculator, from the same distance, the 5D should have more DoF than the 7D, but it appears to be the opposite way here. Is it just variation in the focus or am I missing something?

No.
DoF is identical regardless of format if both the 7D and 5D were placed in the same spot.
Originally, the 5D's FoV (field of view) was greater than the 7D in this test, but OP cropped the 5D images to match the 7D FoV.

Ok, I thought DOF is different unless you stop down the 5D2 a bit more, just wasn't sure how the cropping affected things.
The difference between a ff and crop camera is that the crop only uses 65% of the availalbe light coming through the lens instead of 100%. But the distance is the same. So crop camera is likel cropping a 5diii frame. This does not increase the depth.
A 17mm lens on a crop become an apparent 29 which backs you up for the same field of view and being further away, makes a larger relative depth.
Thus one can simultaneously say crop has more depth per fstop (you are further away) and they have the same depth (from the same distance with the same lens). It depends on your context.

Exactly!
The price one pays for this 'backing up' is difference in perspective. DoF is not a function of sensor size, but focal point (camera subject distance), focal length, and aperture.

But then you are comparing different images so how does that help the discussion?
A key factor in determing DoF is the relationship between sensor size and the combination of (viewed image size) and viewing distance.

elfanucchi: You are welcome. I agree that the difference seems to be small. However, I bought it for fps, more bracketing option, weather sealing, lighter shutter touch.... I still want the best I can get in Canon - and 5d3 is it until they put out a higher pixel camera.
So I agree that the $ difference is large for the difference in quality/iso, but if you are shooting inside for sports/wedding. Or if you were a hdr intensive guy, it would be worth it.
The differences you test for are very small and so are fps, bracketing, sealing, touch.
Would like to see big difference by testing center and edge AF, single AI, moving static.
If someone knows such a test by a resonable open minded person ... let me know ...

Thanks Scott. Your test of high iso between the 7d & mk2 showed me exactly what I wanted to see. Thanks for sharing. I want both of them, but I'm saving and scrimping to buy just 1.

As long as you realize that the 5D Mark II image was cropped down to match the 7D field of view.
Had Scott equalized the fields of view at capture time (using either a different focal length or by changing the camera to subject distance), the 5D Mark II image would show much less noise than the 7D image.
