Canon uses CMOS instead of CCD.
应从几方面来看:
1。350D, 400D,20D, 30D 对镜头的边角成像要求不高。而5D对镜头的边角成像要求较高。所以同样的镜头(如果边角不太好的话)效果是不一样的。有些在30D上表现很好的镜头在5D上就显得吃力了。
2。Pixel density.
5D pixel size = 864 mm2 / 12.8 million pixels = 68 mm2 per million 5D pixels
30D pixel size = 425 mm2 / 8.2 million pixels = 52 mm2 per million 30D pixels
so for the same size area the 30D has higher pixel density, somewhat of higher resolution.
但是有着higher pixel density compact DC的image quality并不如DSLR due to smaller pixel size.
3。Sensor size (and the pixel size).
Sensor size and the pixel size are key factors in terms of noise and dynamic range. Larger pixel size will be very good for noise control and dynamic range (more details). 5D显然在noise control and dynamic range胜出。
