請問以下邊枝鏡好？

Canon EF 100mm f2.8 Macro USM
Sigma MACRO 150mm F2.8 EX DG HSM

Thanks

I don't have any personal experience with the Sigma. Well obviously it has more working distance than the Canon, but it only stops down to f22 so you may struggle to get the necessary depth of field.

May I suggest the Tokina 100 Macro? It seems to be sharper than the Canon 100 Macro. Handling is not quite as good, it extends when you focus closer, but its still decently build, a fairly good AF for a macro and a whole lot cheaper.

睇你影靜態(死物)定大自然啦

同是 1:1 ,
150mm 自然景深壓縮更厲害, 上面亦有網友提出 f stop 問題, 快門要長,另外 150mm 的"手震效應" 亦會明顯d, 值得注意.

100mm 的唔好處亦係要走近D, 影大自然唔夠 150 咁保險

如果計光學質素, 包括顏色對比等, canon 係比 sigma 高半籌.

正廠，20D +Canon EF 100mm f2.8 Macro USM 的對焦速度係唔洗等！！

二支鏡未用過唔知質素,但

長鏡重D,工作距離遠D
影移動物体容易D
但容易手振

短鏡輕D灵活
好多時影marco要蹲低向上或打斜影或要單手持机

此外影marco要細光圈
還有 sigma 150 好似有全時手動(?)非常有用
但對焦有D猷疑 ( 在 nikon 上)
