但考虑到等效600mm只会在室外用到，似乎光圈5.6也可以接受
有没有都用过的人来说说，xzp+2x用来拍航展之类的高速移动目标对焦性能是否可以接
受？ |

主要是我觉得就算是1.4装在2.8上也只有4，拍不了低光了，那索性把倍数提高些。

不过贵

发帖数: 17914 | 5 I bought this converter and used it with my D700 and 70-200 2.8 vrii. I was
very unhappy with the image quality it produced. I ran the combo through
many tests and this combination failed. The loss of sharpness was so
dramatic that I did not think any of the images were usable. The auto focus
had to hunt often and the 3D tracking was limited with this combination. I
checked it through all f/stops and the sharpness was still poor even when
shot from a tripod with cable relase. I actually tested two of these and the
results were varied...but both were very bad. Eventually I tested this lens
with the TC-17eii and was much more happy. The images were drastically
better. Without going into details of the specific tests I ran all I can say
is that in my opinion this teleconverter is for fast long prime lenses. The
70-200mm vrii works much better with the TC-17eii and TC-14eii. Skip the TC
-20 if you ar eusing it with the 70-200mm. |

我老一向瞧不起1.4和1.7的，真求数头发直接上大炮，否则就2倍的，业余玩玩很爽了
