Anyone know how old this lens is, and when it's due to be updated?
One of the handful of lenses that is higly regarded in the line up.
It is rather recent from 2006, so highly unlikely it will be upgraded in the next few years.
All 70-200 lenses offered by Canon are exceptionally good. As they sell pretty well and with the beast 70-200 2.8 II, they are unlikely to upgrade it ... If it ain't broke, don't fix it
5D3, 6D, 600D, RX100
16-35L, 24-70L II, 70-200L II, 100-400L, 50L, 85L II, 135L, 24TSE, 40, 100 macro, 18-55 II, 55-250 II, 600RT x 4
I come here to learn something new, not to learn how bad my gear is - I know that already ;-)!
