Canon70-700mm F4IS 和F2.8 None IS的比较.

因为Canon70-700mm F2.8 IS比None IS的锐度要差.所以我买了None IS的.

用几次感到重了一点.最近换了Canon70-700mm F4IS.

放在三角架上拍两组对比.距离分别是4 和12 FEET.

我的结果是:

  1. 在200 mm, F4的锐度略好于F2.8.
  2. 两者的色调明显不同.F4的比较通透(老话说是比较煞)
  3. IS的确有用.
  4. 背景的虚化有点区别.我个人完全可以接受.

200mm F2.8, 12 feet.

200mm F4, 12 feet.

 

70mm F2.8, 4 feet.

 

70mm F4, 4 feet.

 

200mm F2.8, 4 feet.

 

200mm F4, 4 feet.
