All range F2.8
Light weight (half weight compared to its 70-200 F2.8)
Fast focus
Nice range for APS-C sensors (I am using Canon 400D so it becomes 80-240 in full frame)
Canon lens doesn't have this range, nor Tokina
缺點:
$5300... its 70-200 F2.8 is only $6500...
Could be even better if that is 50-200 F2.8 : )
評價:
I've tried 70-200 and this lens and I chose 50-150 for its light weight and good range to be used on a APS-C sensor. HIGHLY RECOMMENDED.
