It all depends what is the intended purposes

Cannon EF 24-70 mm f 2.8L, 还有Canon EF 11-24 mm F4L are very good for landscape, I would guess.

For portraits, you want to get 85mm F1.2 or 200mm F2.

For sports, you want to get 300mm F2.8 or 400mm F2.8

For birding, you want to get 600mm F4 or 800mm F5.6

• 好！前面我该是写错了, 应该是14-24mm F2.8, 而不是11-24 F4。我用Nikon，镜头也大同小异？谢谢！ -arge- ♀ (6 bytes) () 07/04/2015 postreply 09:16:46

• 人像也未必要8512. 俺的室内人像80%是用70-200拍的。 -fantasticdream- ♂ (40 bytes) () 07/04/2015 postreply 21:15:00

• 多谢！有道理。先添24-70 和70-200 F2.8 的，起步应该够用了。 -arge- ♀ (0 bytes) () 07/05/2015 postreply 08:19:14
