The Sony 70-200mm f/2.8 SSM G is part of Sony professional Gold lineup.
It is actually one of the last lenses designed by Minolta and its current incarnation
is "only" a relabeled and restyled variant of the old Minolta lens. Regarding its
design age it is obviously a full format lens but it does naturally work perfectly on the
existing lineup of APS-C DSLRs where its field-of-view is equivalent
to about 105-300mm in classic terms.
The build quality of the lens is exceptional. The lens body is obviously
made of metal and both the focus and zoom control rings feel tight and
smooth to handle. Typical for most Sony lenses the fluted rubber
rings offer lots of grip but they have an inevitable tendency to collect
dust in no time.
The physical length remains constant regardless of the zoom or focus setting.
The front element does not rotate thanks to the internal focusing (IF) system.
The lens does not feature any seals which is somewhat unfortunate regarding
the (professional) target audience as well as relative to other lenses in
this price class.
The petal-shaped lens hood has an interesting feature: you can remove a
little window cover which provides access to the filter thread - this
is highly useful naturally if you intend to use a polarizer.
Another interesting aspect of the lens is the SSM - the SuperSonic AF Motor which is similar to Canon's USM or Nikon's SWM. It is fast (although not as fast as in the Zeiss ZA 24-70mm f/2.8), near silent and very accurate. Sony did also incorporate 3 focus-lock buttons plus a dedicated AF/MF switch as well as a focus limiter.
