5D iii
The smaller-sized images out of the 5D Mark III are spectacular. They are
much, much sharper and cleaner than images from cameras on which that is
their native resolution. When you start with over 20MP, it looks pretty good
if you use all those to make 11MP or 5MP.
Why? Because they use less, or no, Bayer interpolation. No digital camera
really resolves its rated resolution; they cheat and interpolate up, so at
100% at its rated resolution, no digital camera image is as sharp as a true
scan from film.
At the 5MP setting, you have 100% R, G and B pixels, exactly as if you were
using a Sigma Foveon sensor. If Sigma was selling this, they'd sell the 5MP
(S) setting as if it were 15MP (also a lie).
What this means is that the lower resolution settings actually pack away lot
more detail than you think. The S (5MP) setting of the 5D Mark III is a lot
sharper than any 5MP camera.
是这样的么？5MP 才是 5D iii 的native sensor size？

不全对也不全错把。实际每个像素只能对一种颜色感光。如果是出彩色图，每个像素上
另两种颜色都是插值算出来的。
