With the same lens you will need a longer focal distance (thus, slower SS) on 6D than on 60D. Slower SS - more camera shake. Put it on a tripod or on a bench or a curb and set the self timer to eliminate any shake. And do not change the focal distance (to zoom in on objects). Leave it the same on both cameras.

Subject matter is certainly not the best to be judging IQ. Summarizing the images:

6D used at 1/80 f5.0 ISO 400 EC = +1/3 taken at 11:44 AM
60D used 1/80 f4.0 ISO 160 EC = 0 taken at 6:57 AM

The 6D image is taken with a much higher ISO and EC=+1/3 as compared to the 60D but was at 11:44 AM vs. 6:57 AM. Has the clock been set on the 6D? Seems like a lot more light at 6:57 than at 11:44; granted that might be the case but seems unusual.

When you post some new images see if you can leave the full EXIF intact. We can tell so more about what you are actually doing. 100% crops, even less EXIF.

Actually, the photo with the 6D was taken a few minutes before the 60D. The reason the time is off is because I turned on the GPS which I realized set the clock, but never set it manually, so when I turned the GPS off, it reverted to an unset time.

Will sneak out soon and retake. To get an equal comparison between the two, it's been suggested to use:

  • 1/250 shutter speed
  • f5.0
  • Tripod or self-timer to eliminate camera shake
  • Equivalent focal lengths: e.g., 28mm for 60D, 45mm for 6D

Seems strange, the 6D image, although brighter, is getting significantly more light, almost 2-stops due to ISO difference and +1/3 EC.

Looks like camera shake on my screen.

A full frame sensor will show up more "imperfections" and is a little less forgiving.

If you are going to use a tripod, I'd recommend F8 and a higher ISO for the EF28-105 lens.

I would say shutter speed is not that important if you are using a tripod and shooting a brick wall or static object. The faster shutter speed is really only if you are hand holding the camera.


Use manual with both cameras, and if shooting JPG use the same Picture style, my vote would go to neutral or faithful but i dont think its really going to make a difference.

...and what leads you to make that generalization?

EC leads to the ISO difference. The don't add to each other.

Both the camera and the lens have their own build tolerances.

It may therefore be that the combination of this lens with this body that are resulting in OOF images.

Luckily, the 6d has micro adjustment capabilities which you can try if images shot on a tripod are still OOF.


My wisdom is learned from the experience of others.

It's actually the other way around. The 18mp sensor in the 60D has a much more densely packed sensor and has a higher magnification, so that is harder on the lens, not the 6D.
However, the 6D being a full frame may have softer corners, generally.

Hmmm, i get the impression that the OP knows what he is doing, he has been shooting a long time, so while his posted images may not be perfect i would have though if his technique was bad he would have noticed long ago with his 60D, not just as soon as he gets his 6D.

Its not unheard of for some lenses to be worse on one camera and not on another. I'd put the blame there rather than on the image posted if its most of his 6D images, and with this lens.

I'd say to run some controlled tests, even the DOT.Tune test and maybe use some MFA if needed.

I also wonder about in camera settings like picture style, or even how the 6D images are processed (if different from the 60D images).

it really doesnt matter. bad technique is bad technique. Doing a test at 1/FL is bad technique. In general, 1/FL wont get you consistent sharp results.

Try lowering your ISO speed.

I have read my statement, and your question, several times. I can't find the generalization. There is one specific if/then statement, containing absolutely no ambiguity, about what I would do. What generalization?
