EF 75-300mm f/4.0-5.6 III
EF 90-300mm f/4.0-5.6 USM
EF 90-300mm f/4.0-5.6 DC

Oh, focus speed is also important.
I have used a 75-300 tele lens without anything like USM and the speed is really slow... USM/HSM really helps.

EF 75-300mm f/4.0-5.6 III USM
伊支以我記得
成像係最好
之前考慮過30V搭佢\n但係最後揀左FZ20 XD

咁我想問埋75-300mm F4.0-5.6 III USM 同 70-200mm F4L 成像相差得係唔係好遠呢??

同埋50mm F1.4 同 1.8 用係20D到 邊支比較好?
