Thanks - you're shooting landscape, while I've resorted to "longscape".

Tom_W:
Or are you saying that I should crop the 7D to obtain additional "zoom" effect on top of that gained by its pixel density.


That is what I meant. It would give the same number of pixelx on the target hence a zooming effect and better reach.

Thank you for the link.

You're welcome.

I'm calling it a night.

I've got around 250 LP's in a plastic container in the basement, where they've been awaiting the starting of my project to record them onto CD. By the time I do that, I'll be so old that I won't be able to hear them anyway.


Forget recording them on to CD's (which are rapidly becoming as obsolete as the LP's) buy yourself a turntable & listen to the full richness of analog!

Excellent piece of advise. My collection of LPs is growing.

Both images where shot equally, one minute apart from each other, except that I had the 7D at 10mm(16mm) and the 5D2 at 17mm. I used on the 7D the 10-22 Canon lens and on the 5D2 I used the 16-35L v1 lens.


Thanks for the real in-the-field comparison. This shows that a 1.6x crop body suffers from diffraction well before a full frame sensor body (you're using f16). The only thing I might do differently is use the same lens (16-35) on both bodies and change position to frame the scene equally rather than using different lenses or zooming to eliminate that variable. I've passed on the 5DmkII, but it is truly performing very well here in the small f-stop landscape roll.

I will go out this week and do the test as you suggest and will post my results, thanks for the suggestion.

Bryan Carnathan likes the camera a lot ... and confirms the softness.

Let's see what the defenders of the faith are going to say this time .
He's a very experienced reviewer.

DLA (Diffraction Limited Aperture) is the result of a mathmatical formula that approximates the aperture where diffraction begins to visibly affect image sharpness at the pixel level. Diffraction at the DLA is only barely visible when viewed at full-size (100%, 1 pixel = 1 pixel) on a display or output to a very large print. As sensor pixel density increases, the narrowest aperture we can use to get perfectly pixel sharp images gets wider

Any camera will shoot landscapes. Isn't this obvious? Everything depends on your desired final outcome and presentation. What are you trying to accomplish?

According to the-digital-picture, the 7D's Diffraction Limit is f/6.8, and the 5D2's is f/10.3.

Let's compare a "typical" expansive landscape shot where there may be foreground and distant subjects.

A 7D, at f/6.7 with 30mm lens, focused on something 50 feet away, will give everything in focus from 15.8 feet to infinity.

A 5D2, at f/11 with 50mm lens (to match FOV), focused on something 50 feet away, will give everything in focus from 16.3 feet to infinity.

f/16 on 7D is equivalent to f/28 on 5D2 using above settings.

Conclusion, if you need DOF don't be worried about diffraction differences between the two cameras.

The 5D2 is obviously superior in thin DOF.

Since I'am looking for an upgrade from 40D I am looking for the confirmation that the landscape image that I can create/get from a 7D will be at least equivalent to the one I can get from my 40D today

AFAIR, mRAW is 10MP.

Has anyone tested mRAW against 40D using "settings landscape" ? (I mean wide angles and small aperture).

So far the prints I have made from 7D processed RAW files have been excellent.
I think that is the important consideration here.
