I've been well aware of the front focus problems with my FA* 85/1.4 (showing
up since the MZ-S times, through *istD K10D) and now I've finally been
able to fix it.
The same happens

So I'd recommend to always perform
two focusing tests for each lens correction, one coming from a closer
focus
and another one from a farther one. If you get the same focus, you are
doing
well and you can apply the needed correction.

I've found that it's almost impossible to see minor differences in
focus o the camera's viewing screen. I shoot the images as RAW and
transfer them to my computer where I can compare them at high
resolution on a large screen. Of course my old eyes aren't very good,
but I would think it

I am now officially curious
So far, the three DA lenses i have. The 50,16-45 and 50-200.
BUT
It seems an issue with more close up subjects. If i am shooting
something with some bulk or size to it, all seems fine.
I cannot get out my door at the moment, so i'll retest all three this
morning, however i thinl its going back,
Opps fo r got the A50, which started all of this for me.:-[)

Wait a minute. The A50 isn't autofocus. If you're having problems
with that, you have some kind of focusing screen misalignment or
other related hardware problem.

the following calibration settings for the K20D:
DA 12-24 = -6
DA 16-45 = 0

If so can you now see an improvement.

If you roll back the firmware to an earlier version you can do it via

But it will apply to all your lenses. So if you make it right for the FA 50,
the FA 20-35 and the DA 40 will be off. Unless all your lenses are backfocusing
or front focusing, leave it alone.

I suspect all this lens testing I'm reading about is due more to the
fact that its winter you guys up north have nothing better to do :-)
I'm just happy that my K20D's focus is more acurate than my K10D (BF
issues). I'm too busy taking photos, I currently don't have the

No problem. I'm not pleased about the idea of getting at that debug
mode. And you folks have convinced me that the lens by lens adjustment
is the only way to go unless I've notice some serious problems. Given
the situations when I'm likely to use the FA 50 wide open (dark or
macro), I'm likely
Yep. Were it not ugly outside, I wouldn't have time to play with
