你冇理由唔知 FF= full frame 喎...
之前果支 600mm, 唔記得光圈係 f6.3 定 f6.8, 新果支 800mm 係 DX 鏡, 光圈又細左, 所以外型冇大到..
The old one should be 500 F6.3 in full frame. The price of it in Wing Shing is just HK$1800. However, the comment of it is not so good. For the new one, if the price is below HK$3000 that is OK for try try. |
