Hey Jeff, just to throw a monkey wrench in the works,. I just went back to page 100 and fast forwarded through to the point where you mention having problems with your cameras image quality, and although most images posted do not have EXIF readily availble from flickr, the ones that do, or the ones that you mention it, are all shot stopped down. Sometimes as much as f/9

Any chance a change in your shooting settings is contributing to your issue?

Jeff has to shoot wide open... have you seen all the dust inside his lens? That lens needs all the light it can get.

Foot looks quite sharp to me....
I think shooting a focus chart would be interesting and give a better insight as to the point of focus.. Just an idea..

I believe Jeff has declined to do controlled testing.

It's a point I too noticed. Also, shooting from some distance will widen the DOF a lot. Those critters at 5-7 ft and wide open have razor thin DOF in a 100-400 at 350mm (about 1/4"), and we can see this in the last images.

The feathers above the claw and wing tips look more in focus. The head is closer to the camera.

Controlled or real world, whats the difference.
It's pretty obvious the camera is not what it used to be.
The guy just wants his camera fixed.
You a canon tech in Toronto, Archibald?

Not a very constructive reply....
The point is that no one seems to know where the point of focus is on the posted photos and that shooting a simple test chart would show the intended point of focus and the actual point of focus....giving a much better indication of what was going on in the camera.

That would make sense Don if you haven't been doing this for almost 5 months, I just went out and shot with any luck my last few hundred images with that camera. My loaner is in town so ill shoot that tomorrow and see just what I think of it.

It really is tough for everyone to see. but rest assured this is not fixable by anyone at home. This was caused in shop at canon service and they alone need to fix or throw it in the trash. I do hope there is a positive outcome. so before we have fisticuffs I'm gona get dinner ready as the wife will be home soon and I don't wish to receive the dirty end of the stick tonight.

I should also add......CANON REPAIR SERVICE ..said..... NO FAULT FOUND.......after having for three weeks and me getting them to look one more time in ways that only skilled phonology can provide.

forum: Canon EOS Digital Cameras

These examples with the 7 foot distance and 350mm FL require careful analysis and consistent Af results. Without using Spot Focus, I don't believe you would be able to determine / match AF placement and consistency with the resulting actual plane of focus in the image; since the total dof (7ft, f5.6 and 350mm) is a Total of 0.26inches.

I am not weighing in with an opinion on whether these were sharp/aligned/consiste​nt, but rather with a word of caution.

Certainly, nobody should be forming opinions based just on these tiny postings.

It's not in need of MFA....some shots are front focused some are back focused..

Per my other post, we can only determine whether front or back focused is to see the focus point overlay on the image to line up and really understand where the camera would have attempted to place focus plane. Otherwise we are guessing without more info.

I totally agree with you...
I was hoping to see a focus chart but it doesn't look possible..

Are you saying Archibald you think the image at the top of this page is back focused ?? because it look front to me

To me, yes, back focused too. It was a weird angle you shot from that makes it more difficult to analyze since the plane of focus will be further away at the bottom of image, and closer on top due to shooting from a low position. However, assuming Af point was on his forward leaning head, look at the tiny fine details at the outer edge of his shoulders, just below, the black shoulder stripes.

The bluejay image is much simpler, less upward angle such that the leaning plane of focus caught the branch too. (top closer falling on face, and bottom further at feet./branch.)
