Issues with 5D Mark 4

[TylerEdmonton]

Having serious issues with noise and sharpness above ISO 320 and have since purchases. Canon techs have had it for a month and claim it's fine. Mark 2 body has no issues with the same lenses. ANY creative solutions appreciated or it mnay have to be retooled as a fishing sinker...

Post a sample shot, with exposure, focusing, and lens info.  Tell us what is wrong with it.

Image shot at ISO 1250 f.4 at 1/80s using Mark 4. Notice the softness in the focus and the noise vs skin tone. I immediately changed to a Mark 2 and the results were much better

What focal length did you use?  That is a fairly slow shutter for a portrait, IMHO.  Did you use a tripod?  Why didn’t you pos tthe “good” photo?  For now, I am going to blame the softness on camera shake.  Convince me, otherwise.

Looks like a focus problem to me, the front of the dress is much sharper than her face which is where the focus should be.

It was shot using the single AF point with expansion option over her face. Maybe the autofocus system is a little off.

I am not convinced. Tripod? Focal length? The whole image is uniformly OOF, including the piece of jewelry. It looks like camera shake from a slow shutter speed. Sorry.

shot at around 60mm. Same as the ones I shot immediately after on the Mark 2 which are clean and sharp. And this is why I asked Canon to look at the cameras autofocus and its communication with the lens. A 7D I had, which used the same sort of autofocus system as the Mark 4 does, needed to be reset all the time and the firmware reinstalled.

The goal of using these forums was to see if anyone else had experienced anything and found a work around.

If Canon said the 5D4 is good, then it is good. Look elsewhere for the cause. Try a tripod. Prove me wrong.
