周末在家试试镜头 85mm 1.4G Vs. 135mm F2 DC Vs. 105mm F2.8

下雨天，不能收理院子.  没什么事.  正好同事借给我一只135毫米DC镜头.  测试颜色和背景虚化. 

相机D700 on 三脚架，SB-800 TTL + 白色伞.   没有后期处理- direct conversion to Jpeg

1) 85mm 1.4G at F1.4

2)85mm @ F2

3)85mm @F2.8

4)135mm @ F2

5)135mm @ F2.8

6)105mm @ F4 - This is the max aperture at macro situation

7)two SB 800 85mm 1.4 @ f1.4

This is not scientific at all.  But the 135mm DC is giving a very nice Bokeh at F2.  Can't wait to shoot some models with it.  Also, some bokeh could be enhanced by adding a well soften light to the background. 

There are so much to learn.  Your comments will be greatly appreciated.
