镜头升级, 大师们帮我分析一下

自从开始用85mm1.4G，基本上不用70-200mm VR II了.  想卖了70-200mm 镜头, 升级到 200mm F2 VR.

根据Photozone所做的分析, 200mm F2 is much sharper than 70-200mm at 200mm at F2.8. 

用过200mm的大师们，请给说说 Pros and Cons (other than it is heavy). 

70-200m is my last zoom lens.  With a 35mm 1.8G on DX and 85mm 1.4G on FX, I have most of the shot coverred.  To shot sports, than I could use my 328.   

所有跟帖： 

• F2.8，70-200比200的sharpness差很多。至于焦段，各人习惯不同 -WayCool- ♂ (0 bytes) () 04/21/2012 postreply 12:48:22
