i have some questions
1) BF and FF is because of the calibration problem, a pentax lens can be easily repaired if it is sended with the body???
2)weather sealing could get off from lens and service could repair it????
3)conclusion, the 16-50 couldn't be repaired, has to be replaced, if only the lens has decentering problem????
i ask this questions because i won't get the lens with warranty. i just trust the Pentax service here.
what do you think???
