Re: why micro focus adjustment not in the camera ?

Among six A-mount AF lenses I could use on NEX via EA2, only one has a noticeable back focus issue. In this case, the LA-EA2 simply stores the information for that lens and compensates. If I were to get the LA-EA2 adjusted for this lens (so no MA is needed), then the others will require to be compensated for. So, technically, in this case, it is the specific lens.
