I don't think AF micro adjustment will work
with this [Commlite] adapter.
I also think it won't. But I'm very OK about
your proving me wrong ... Inquiring minds
are hungering to know !
Should be simple to find out. If it's greyed
out in the menu, it's not available.
If there is no beam splitter in an adapter,
then it has no SLR-type AF sensors. SLR
AF sensors depend on a substitute image
delivered by a mirror. Both the mirror and
the sensors are sources of error, as there
is no assurance that they are located with
Any AF adapter that lacks a beam splitter
MUST be using the imaging sensor to AF.
There's no other way for the AF system to
acquire focusing information. There can't
be any mislocation of any AF components
when the AF sensor is the same sensor
that 'sees' and records the focused image.
Where the imaging sensor is also the AF
sensor there's no use for microadjustment
so the lens is to blame. It has backlash but
if it worked OK on Canon SLRs then those
cameras were programmed to "re-finalize"
focus, to re-tweak the lens to better focus.
The Sony AF is either not doing that or it's
doing too little of that.
