I have tried and returned three MKIII's for AF issues and gave up on them completely in February. My MKIIn works better.
However, gymnastics / basketball season is here and having a usable ISO 3200+ would be nice....but I am still pretty put-off by my earlier experiences....
Has anyone experienced the crummy AF issues lately with newer MKIII's...and what serial numbers are the latest versions now? These things working now?
Not trying to start a war here folks....just looking for some honest experiences with late model examples.
