Originally posted by fewing1 d the autofocus doesn't seem to be working.. I was wondering if someone could answer some questions about this lens. When I have it on full auto, should I not hear/feel it trying to focus?
Maybe, it is very quiet so maybe not. But you should definitely see it move into focus.
Originally posted by fewing1 With the quick shift is there a wrong way to turn the focus ring. I thought I understood that you press the shutter half way to have it auto focus and then when its locked you can turn the focus ring to fine tune it(making sure the shutter release is kept half way down)
No, there is no wrong way. It goes either direction.
Originally posted by fewing1 Can it be turned all the way around or should it be turned all the way around? should I be rotating it in either clockwise or counter clockwise to focus?
It goes all the way around, though that also means you can turn the ring further than infinity, but of course the lens stops there, just the ring continues to turn, there is no 'stop' as on manual lenses.
Originally posted by fewing1 The copy I have seems to almost drag if I have it on auto or manual. The focus ring doesn't seem freely move as some of my other lenses.
That seems odd, mine has no drag at all, just butter smooth. Though you should feel the slight 'stop' when it comes to the end of the focus range. Just a little click and then the ring continues to turn. Watch the distance scale as you turn and you can see it hits the stop and just keeps going.
I have bought most of my lenses used, but I did buy the DA*16-50 new. And ended up with a bad SDM motor that required repair. Still after 10,000 images with it I am not complaining. But at this point I would not buy one used, only new with a warranty. Just my opinion.
