FA*400/5,6 AF problems

I have a FA*400/5,6 which have worked great on all my cameras, except K-5. On the K-5, autofocus seems more nervous and quite often cannot lock focus at all. On my K-7, this lens is next to perfect.

Has anyone here experienced the same behaviour on their K-5 or do you think its only my K-5 having this problem?

The first question I would ask is if you have the focus point settings the same on the K-5 as you do on the K-7 - center spot focus or auto point, etc.

And the whole "AF-S" (single) vs. "AF-C" (continuous) switch thingy as well...

I think you should send it over to me here in Shanghai .... I can get it repaired for you very cheaply and then test it thoroughly for you. Though return post may be a bit slow, say like 6 months ?
