Admittedly , it's sounds like AF is more out than Micro adjustment did .

It sounds more like you have cleaned the sensor and failed to place the mirror back in its correct position .
It needs to be clipped firmly in place .
With the mirror slightly off , AF would be well out .
I think that's the first thing you need to check .


Ok so I want to THANK YOU for this. I never would have thought of this. I did clean it at some point, but couldn't remember when, but I figured I it was worth a shot. I popped the mirror out and pushed it back in firmly. And it seems to have fixed the issue.

Interesing that you have not noticed a focus issue before ... unless the timing of the firmware update intersected the time you cleaned the sensor ... hmm.

All's well that ends well .

Always check the basics before looking for the complicated answers .

I guess now you just need to reset each of your lenses AF micro adjust back to what they were ?

Depends .
If the O.P tends to shoot wide angle with small apertures DOF might have covered this sufficiently to hide the focus error .
Longer focal lengths with large apertures would make it obvious though .
Portraits especially , like where she's focussing on the dogs eye , but the ear's in focus instead on the taken image .

The timing of the firmware update and the cleaning was close together, which is why I never thought of it. My husband reminded me that the day after I did the upgrade I was thrilled with the focusing. But I was annoyed by the dirt specs on the pictures (it was a day of blue skies, so more noticeable) and asked for his cleaning stuff (he's into photography as well).

I didn't go take photos for another couple weeks, so I didn't really think anything of the cleaning part of things.

I don't often shoot wide and smaller apertures, but tend the other direction (mostly dogs in action and dog portraits), so the change was noticeable.

Thankfully there's no major microadjust to fix. I only did it on two lenses and so it's easy to get rid of it!

Once again, it would appear to be just me. Though I have to admit I'm curious as to how a spring loaded mirror which only has two positions, up or locked down otherwise it would just be "up", was not seated correctly and throwing off auto focus.

Honestly? I don't know. Maybe it wasn't clicked in on one side completely. I was very delicate about putting it back in because I was scared to mess it up. All I know is I popped it out and more firmly pushed it back in and now when I focus on the eye of a dog, the eye is in focus.

I didn't honestly think it would fix it, but I thought it was worth a shot. It must have done SOMETHING because the focus was most definitely off before and the last two shoots I've done, it's not been.

I was cleaning my sensor and when I put the mirror back down, barely touched it with my fingernail. DONT DO THAT!! It's like tin foil, made a little dent on the corner, but not seeming to affect focus. I rarely use AF anyway though.

Oooo yikes! I think I was SO careful with it the first time, it might not have clicked in all the way. This time everything is working ok.

This is part of why I didn't want to clean it myself! I still need to clean off some of the dust as I had little luck with it, so sometime maybe will send it for a professional cleaning to someone.

Here's one of the shots from after I reseated the mirror. Really appreciate everyone chiming in!
