|comment:||This lens is a dream! Autofocus is faster than I imagined, the lens NOt being the Hs-version. Though I haven't used that HS-lens, I can't imagine the focussing speed being much faster. it isn't as fast as the 70-200mm f2.8 ssm though.|
On the other hand, it is almost as silent!
Af is fast enough to track a flying bird at about 20 meters away
With the sony 2x teleconverter (sal20tc), sharpness is still extremely good! Wideopen, there appears to be a little bit softness. Everything above f4 is sharp as a newly sharpened pencil!
Important: the latest teleconverters (from minolta apo II onwards) have a lower speed gearing, so putting a sony teleconverter on the lens actually slows down the lens Af motor by half. It is better to use the original minolta apo teleconverters, but I find the lens+ sal20tc still usable.
the lens comes with a nice case and some drop-in filters.
the tripod collar seems a bit short to me.
the weight is reasonable for a lens this size. It is usable handheld at 300mm, not at 600mm. You'd need a decent tripod and a decent ballhead for that.
the front filter is really big and really axpensive (and not easy to find)
This version of the 300mm f2.8 lens is cheaper that the Hs-version and I would recommend buyign this one and saving a couple of 100ds of euro. the Hs version's Af is probably faster, but maybe faster that you'll ever need.
