FA*20 on K10D...

finally I bought this lens...
but since early shots I have seen problems of back-focus.

My friend told me it's a common problem of fa*20 + k10d...

oh no....

what do you think?

Hi Angelo,

Do you mean FA*24/2 ?

Mine works fine but with K100D, though.

Can't you go to debug mode?

If you are referring to fa* 24, it does not backfocus on mine. Just lacking a little colour in broad day light. I would have preferred this lens used in low light environment as it creates the moody atmosphere very well. It does not do too well in the colour and contrast department like fa 31 ltd

Wow.. I ask for a 156 and I get a Spider! Right on!


So for the debug mode, you have two options:

1) if u have firmware newer than 1.10 you'd have to roll back to 1.10 and get into the debug mode.


2) Or you can use this new piece of software that came out recently, which allegedly gets you in debug mode.



some threads for you to read:
