我两张都用的新头,手持. By looking at the first image, the lens already shows very good sharpness under the 手持, F4 and 1/10 second condition.
你用什么相机测的?D200
测35时距离是多少?about 35 feet. This
用这个头拍要虚化背景是不是有点难(光圈不够大)?是有点难.
你测试的五张卡贴的位置亮度不同,对结果有影响吗? Not at all. We are looking at the sharpness. Besides, I used single center focus.
