請問以下邊支Macro len 用在Canon 30D效果最好而日後又想用在FF上？

1. Canon EF 100 F2.8 USM
2. Tamron SP AF90 F2.8Di (not for FF)
3. Sigma AF 70 F2.8 EX DG
4. Sigma AF APO 150 F2.8 EX DG HSM

Thanks!!

#1, 150mm too long for 30D, very difficult to focus.
for 100mm, it is also quite difficult to to focussing. However, it is a good range for FF. Can be used as portrait lens.

The lens quality of 100mm is also good. (almost up to L lens')
Another point to be considered: Will you take insects or flowers? If you take insects, you cannot stand too close to insects, then you need a tele lens. (100mm + 30D --> 160mm already)
