So I'm going through my transition from a K5iis to K3 Phase where little quirks get me ancy.
I've noticed when going from one end of AF range to other (infinity to close or close to infinity it doesn't matter) that the AF makes a couple braking maneuvers before settling in. This has actually lengthened my focus lock time from my k5iis.
I still have my K5iis so I did quick comparison on 4 lenses and got same results from K3 - it closes in on focus, brakes, zeroes in and locks.
The set up - AF Spot, TaV Mode, indoor, version 1.10
Lenses tested - F50 1.7, sigma 100-300 f4, tarmon 17-50 f2.8, FA 28
the first lens I stuck on the K3 was the f50 1.7 just to make sure everything worked and the AF did its stuttering. So I stuck on the 100-300, and then the Tamron since they are 3 diff manufacturers. at least I'm getting consistent results.
does the K3 eventually break in and this go away? understand AF is my pet peeve with the K5iis so I'm a little hypersensitive about the K3 not living up to my expectations.
and no I have not done any lens calibrations, haven't had the time, but if that's the answer are we talking a global adjustment? what a pain
