1. Is anybody aware of the stronger AA filter?
2. Or the fact that raw files at high ISO are not that different - according to DPreview samples -between 5D2 and 5D3? Are all of you shooting jpgs only and are so impressed with 5D3?
In order to not be misunderstood: I am interested in 5D3 too. I am just having second thoughts ...
The Raw files have a huge difference at ISO 12800 and higher, but at ISO 1600 are similar. I bought mine to be able to use 12600 and higher ISO, and my 5D MK II is a total mess at ISO 12600.
It all depends on the definition of High ISO.
For some, the difference in AF speed and accuracy means little, however the auto ISO in manual is very useful. It could be better, but its still a big plus over the MK II.
There is absolutely nothing wrong with the 5D Mark II, but you can look for reasons to keep it or get one, or you can look for reasons to buy a 5D Mark III. It really depends on your mindset, but its hard to go far wrong.
I took 300+images of a Monster Truck that a friend drives a couple of weeks ago with my 5D Mark II. It worked fine. Then I boxed it up and sold it. I doubt that the Mark III would have done any better.
