Originally posted by LeDave Off-topic but couldn't resist, that Tamron 70-200 f/2.8 is a beast! I used to own one. Right now I am having a hard time deciding between that Tamy or the DA* 50-135 f/2.8.
If I had a chance to revisit my decision, I think I actually would have gone with the DA*50-135
only because of the weathersealing. Besides the weathersealing, there is no reason I would choose the 50-135 over the 70-200.
Originally posted by eddie1960 While I like the quiet of SDM, there is nothing wrong with screw drive, it's a reliable proven tech. SDM for the higher end lenses ok, but the entry level can be screw drive (and in fact they will need entry FF lenses too not just the top level ones - entry will outsell the top models providing the cashflow for the production of others)
I don't mind screw drive either, but it's nice to have a set of pro lenses that have quiet
and fast AF. When adjusting for small focus changes, the screw drive is actually really silent. But when cycling through the range because of missed focus... in a nice dark quiet performance hall
