優點:
1. Good Quality for this price ($12xx water goods)
2. Good looking (feel better Sigma 70-300)
3. Light and easy to handle
缺點:
1. Focus speed very slow (I used Nikon D80 & D200).
2. Macro only at 180-300.
3. Waste time to change Macro=>Normal.
評價:
1. Cheap lens but with good PQ (only $12xx, so worth it).
2. I used 70-300vr and 70-300ED before. I feel the PQ are in between them. Also the appearance is quite professional.
3. But the speed of focusing is a big problem.
4. Still recommend if shooting object not moving fast and in day time (not good to use in dim situtaion).
