发帖数: 25662 | 22 1D上的f2.8的点支持某些f4的镜头使用其f2.8传感器可以试一下这样理解
中间突出那行f2.8有larger sensor pixels，于是更sensitive to light，同时have a
larger pitch。所以基线比f2.8短，比f5.6长，加上larger sensor pixels对f4下的v
ignetting有改善。所以还是能用到这部分的line sensors的。
至于为什么有些f4能用，有些不行，这个应该和镜头的main lens exit pupil设计有关
。只要把f4那组line sensor back project回到exit pupil上，有些f4镜头设计能包括
f4的back project，这些镜头就能触发f4的line sensors。 |

dynamic range is a ratio of gray luminance; it has no defined unit per se,
but it can be expressed in Ev, or f-stops.
