Re: Canon EOS 7D Mark II Soft focus


@magmowrote:

Thanks, here are 2 images taken today. Both are shoot with Canon EOS 7D Mark II and Canon EF 70-200 f/2.8 L USM. Focus point has been on word "Canon" on the lens in the image (not the lens hood)

 

 f2.8, ISO 100, 1/160 at 200 mm

f2.8-iso100-160.jpg



Second image 
f/4, ISO 100, 1/160 at 200mm
f4-iso100-100.jpg







There is probably nothing wrong.  You are focusing on a fairly close subject using 200mm and f/2.8. You DOF is quite narrow.

Re: Canon EOS 7D Mark II Soft focus

@waddizzle, I disagree there are 2 versions. One with f2.8 and one with f4. If it is a DOF issue then the f4 version should have been in focus or at least better than the 2.8 version which is not the case.

Do you know how to use and read that table?

 

It is not a matter of whether or not you agree with me. You are disagreeing with the facts. I do not know what distance your subject is, but your DOF is probably less than half of an inch with the f/4 lens, and even less at f/2.8.

Re: Canon EOS 7D Mark II Soft focus

Anyway, if I focus on the word canon the focus should not be a bit back as displayed on the images

Re: Canon EOS 7D Mark II Soft focus

Did you shoot the images handheld or on a tripod ?

 

Have you tried liveview focusing ? Take some images with liveview focusing or even manual focusing and compare to the results of focusing using focus points.

 

Magnify the images taken with different focusing methods and compare them. Then you may consider whether you need to AFMA for individual lenses.

 

Try shooting in a controlled enviroment, may be avoid some lighting conditions that will reduce the contrast of the subject or even confuse the focusing sytem of the camera.

 

Focus screen will not help you in auto focus at all. Try manual focus with subject magnify in the liveview to acieve critical focus. If softness persists, you might also have problem with your lens(es). Glasses may have to be re-aligned by Canon.

 

Good luck.

Re: Canon EOS 7D Mark II Soft focus

Hi, i used a tripod. I am not happy at all with the picture Quality/sharpness and really expected more from a lens like this. I will send it to Canon after this weekend and will post the result when I get it back

You might want to send the camera and the lens, too, if you can.

I figured you used a tripod.  What focusing mode were you using, One Shot or AI Servo?  IS, on or off?
