这个D800一手实用评测提到的:"Oddly, the 28-300VR is actually rather
impressive at 300mm on the D800 – NOT something that could be said about
the lens on the D700. In fact, it performs much better on the D800 than it
did on my D700 – curious considering the demands of this sensor."
看来是有点magic在这个头里,这下这个狗变要翻身了。 |

看DXOmark 28-300的200-300间比70-300还强些。但是70-200那段不行。
实用起来感觉70-300成功率会高一些。对焦快,抗眩光好。
sensor密度大,对所有狗头都是提高,所以狗头在D800上比D700上好,不足为奇呀。
问题是牛头会更好呀,比如300/4。

狗头上了高分辨率,低ISO的时候,肯定是提升呀。
MTF要做乘法(其实是卷积),body提升里,画质自然提升呀。
