小弟打算upgrade 5d mkII
但覺得支16-35II 買得o黎唔值成皮野
請問咁多位C兄
支 Tamrom 17-35 F2.8-4 除對焦速度外
PQ 會唔會爭好遠?
因為個差價可以入支百微L

picture quality 16-35 II is not much better than 17-40. If u shoot RAW and use DPP to correct the CA, the quality of 17-40 on 5D mark 2 is quite acceptable, u can also save at least 5K for other lenses

How about the one of Tamron 17-35mm? At least I can have F2.8 aperture at the wide end.

17-40mm has pretty bad distortion from 17-24mm. The color is also not as solid as 16-35mm or 14mm.

Can 24mm f/1.4 compare with this len ?

Canon Wide Lens is her weakness........IMHO

[王迦南]

FF鏡最Ultra Wide應該係佢喇！

[h0001244]

I think Sigma has more advance technology in making ultra wide angle lens.

when there are Canon 17-35 Nikon 17-35 Tokina 17-35, Sigma got 15-30 alread.
when there are Canon 16-35, Nikon 14-24, Sigma got 12-24 already though it's not F2.8 lens
