So I have a Sony a300 that had back focus. Its not under warranty so I decided to fix it my self. Turns out its pretty simple.

How many of you ever done this to your camera?

I'm not scared. :lol:

I fixed focusing offsets by using the micro-adjust function :) Be so much easier if they put it in every body and not just higher end ones.

If memory serves me correctly, on the a300 isn't it done by some screws under a label on the bottom? Did you find it hard to dial in the right adjustment? And does it work well for all your lenses?

Yes there are 3 screws on the bottom under the label. Did some focus test at 45 degrees and turned all the screws clockwise 1/4 turn.

Wash, rinse, repeat.

Took about 5 tries.

Hardest part was removing and setting back on tripod.

And good question about all lenses. Will get back with you soon on that one.
