I am new to the 7d, just bought a used copy a few weeks ago, now I am coming from a t3i, same sensor .. I have been shooting both on same settings and it seems the t3i rebel can Achieve better autofocus when useing one shot single center point, I do t have example pics but the 7d was struggling more then the t3i, is this normal??
I know in AI servo the 7d shood shine, but I am worried now I will not achieve sharp photos from the 7d..
I like to focus on say the eyeball of a subject and zoom in on play back to 100 percent to see if its tack sharp and I don't see this happening with my 7d kind of disappointing, do I have a bad copy ??

I never used the 7d. I have a t3i. I find the files to be amazing. I read tha the 7d has an anti aliasing filter that some have complained about in the past. Not sure if this is what the problem is or not.

Have you made sure you are not using any of the other focus modes like focus point expansion or spot focus?

I have only used basically single point thus far..
I tried spot focus, and expansion, and all 19 point and zone, I am a single point auto focus user, and my rebel seems to be better then the 7d..

Post the example pictures.

The 7D does have a learning curve, but with the most basic settings it will focus faster in any mode than any of the XXX bodies. There is a rather aggressive filter that can make SOOC images look rather soft, but can take fairly aggressive sharpening as well. Need to check MFA on your lens, not sure why but my 7D requires MFA on all lens while my lowly T2i seems to be spot on with anything I stick on it.

The 7D can cause a lot of anxiety and frustration coming from a T body but with some patients and practice it is a solid performance body that can do amazing things..

One thing I would do first, since you bought it used is to go and reset to factory settings, just to make sure the previous owner did not tweek something. Then take another test shot and post for us

So micro adjustment might help with the lens attached to my 7d..

Also comparing t3i and 7d while viewing images on rear LCD, the t3i looks to show true colors while the 7d images appear off in color ??

Very weird, do the colors in the images look different when viewed on your computer..

No expert here but I believe the displays are very similar and should look the same.

As far as MFA, that will affect sharpness only, not focus speed. If you are seeing slower focus on your 7D something is out of sorts. If your concern is that the images are not as sharp than MFA may help. But the SOOC out of camera images on the 7D do appear softer than most. A little PP fixes them right up.

What picture styles do you have selected for each camera?

The picture style on both body's are on portrait..
I don't find autofocus slow in 7d
It just missed focus on a subject a few times were the t3i did not miss focus..

Yeah the images on rear LCD are different in color between both cameras, not sure on computer, will try that ..

How did you make your own adjustments?
You say the color should be same on LCD and computers screen?
