優點:
cheap IS
output quality good
range is good
缺點:
super plastic, like a big 50/1.8
EFS
IS not really effective at 200-250mm, (becoz u using about f/5.0-5.6)
it only can work under sunny , long distance, not any darker environment.
if IS can't work usually, this lens is expensive
super plastic again even the mount
評價:
i think anyone want to choose a tele- lens
70-300IS is a better choice
pay 1500 more for a 2nd hand
or use sigma or tamron
