Issues with 5D Mark 4

TylerEdmonton — Mon, 15 Apr 2019 22:27:25 GMT

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.

If Canon think this is good I guess I'll be looking at changing to Nikon...

Your complaint is not uncommon. So is your threat.

Very high resolution sensors are unforgiving of operator errors and even some lenses. A small camera shake on a lower res sensor does not affect as many pixels as it would with a higher res sensor.

Was your sample photo was from before Canon looked at the camera? Can you take a test shot with a tripod?

All takien before Canon looked at it. Its currently being shipped back from Canon

None of that explains the noise I'm seeing however...ISO 320 looks like the examples in reviews shot at 32000...

It was a general comment not specific to that image. I figured this forum would be a waste of time...

Whatever you say, guy.

Let’s wait until you get your camera back. Take some photos using a tripod. Like I said, high resolution sensors will expose whatever flaws someone may have in their work flow or gear.

You wanted answers, right? The good, the bad, and the ugly truth? I think even you should admit that your shutter is probably too slow for the focal length. If you want specific solutions, then do not make broad, general comments.

I am having same issue. Did you ever find something to correct this?

Re: Issues with 5D Mark 4

perdewk — Mon, 15 Jul 2019 12:41:32 GMT

I am having SAME issues and it is annoying. Any resolution yet?

Re: Issues with 5D Mark 4

You can't be having the SAME issues because as the above posts show the problem was never resolved and the OP now seems to have gone quiet.

I would suggest you start a new thread stating exact details of your problem together with a sample picture that shows the fault and includes the full EXIF information then other forum members will be happy to help you.
