論 5D3

Rumor says the 5D3 spec is:

22MP
61 AF points
dual CF/SD cards
$3500

The question is: How reasonable is this rumor?

1. 22MP is reasonable.

2. 61 AF points? This is the most questionable part. Before the Nikon D800, I would not think so. But now, Nikon has a high pixel camera with pro level AF, so it is quite likely that Canon will upgrade the AF system on the 5D series. In fact, if 5D's AF system is less than 7D's, Canon users will be quite upset.

3. dual CF/DS cards. I think this is a waste of resource.

4. $3500? A little too high. 5D2 was only $2700.

ISO noise? It should be at least 2 stops better than 5D2. The 1DX with slightly lower pixel count seems to be 3 stops better at the pixel level based on the available ISO settings.

FPS? I think it should have 5-6 fps.
