p.1 #1 · Check your 5DIII for MFA if you havent touched it

I read on one of the topics here that the 5DIII has a bug which changes the MFA to -8 if you havent changed it.

Checked my wifes camera. VOILA -8 MFA!! No wonder they are so soft!!
I changed mine to -2 and seems to have stuck, but my wifes never changed it...

Yep mine was at -8 also. But that was only for the general "all lens" setting so it wasn't affecting my individual lens MFA values. There was a thread about this last week. It was a surprise to see it when I went and looked.

Mine sets ALO to on everytime I remove the battery and or change any Canon lens

The setting does not change with a Tamron 28-75. Seems like a EF Lens version issue with the FW ?

Doesn't look like this info is recorded to the EXIF..at least not the info display in DPP. Is there anyway to tell from a raw file if AMFA was applied at the time it was taken?

It does show in EXIF, but only if the value is not zero.

In my version of DPP AF Microadjustment is the 24th item listed on the Shooting Info tab. Immediately following AF Mode and AF area select mode. This is for a 7D with DPP version 3.12.40.0

For some reason, it doesn't always show on 5D3, and this morning I noticed it doesn't always show in EXIF even if it was set - seems like there may be another bug in the machine. I took one photo this morning that I know was set at +15 and EXIF did not show an MA number, nor was the image taken using liveview...

Weirdness. But I think I finally have my lens dialed in. Hopefully!

ARRRGH. SO it is due to a freakin bug.
Ive shot two weddings and could not understand why my 35L was back focusing at F2.

Then I decided to check my MFA settings, they were adjusted heavily for some reason. It was set to zero last time i checked it.

This sounds like pain. Canon should serve this issue fast. It is not very comfortable if you have to check your MA settings, every time you change a lense.
