Weird.  Just...weird.  Thanks for clarifying!

As for AFMA, here's a place to start:  http://www.the-digital-picture.com/Photography-Tips/AF-Microadjustment-Tips.aspx

Currently, I just use Reikan FoCal software.

I'm not positive what Noise Reduction you are using if any... but if you have NR on, it CAN soften the image as it tries to squash the noise...  So a lower ISO with no NR needed will look sharper than a high ISO with NR applied.  Personally it looks acceptable, micro adjust can fix it a tad, but it looks like a NR thing to me...

Perfect example of how content and story is far more important than IQ, NR and all the rest put together, I’m drooling for all those lil’ 135 boxes. Bet that shop smells real great and yes I have a totally romantic unrealistic view of the past. ;)

Higher ISO = more noise = less details (since the details get replaced by the.....noise!)
Focus looks fine.

Turn off in-camera auto lighting optimizer, noise reduction, tone priority mode and then see what comes out.

this is why i sold my 7d. Terrible focus....after it decided not to anymore. Was great at first.

and with no other canon body in its class, good luck with this one.
