Re: FA* 300mm f4.5 jittery focus problem?

I own this lens and the description of your AF-behaviour is on the spot with my lens too ;(

I asked the same question you did quite a while ago, but didn't get useful information.

If I use the lens on my K-r I do NOT have this issue... if i use it on my K5 and a K5 of a friend... same problem ;(

It's the same problem, I guess.. changing focus 3-5 times /second in a smaaaall amount, and realeasing when image is not always sharp... you hear it and you feel it, right?

I am using this lens more often in MF due to that reason... which is quite sad as I paid a hell a lot of money for a fast AF-Teleprime... images are awesome thought, tack-sharp and really colourful. not saturated, but...welll.... I like them.
