I've read through a bunch of articles about going FF, and everyone has said "You lose the telephoto end by going to an a900" and I have to stop and think if that's actually true. We all know the APS-C is just a cropped FF, so does anyone know what the resulting resolution would be if you cropped a FF 24MP image down to the coverage area of the APS-C? It's gotta be pretty close to 12MP, I would think, but I'm not thinking clearly enough right now to try it. :D

As far as i know it will be around 10-11 MP it will be lower than the a700 but if you think that already 10 MP is more than enough then is OK.

I thought about it many times. Most of the test they made with a900~Nikon D3~Canon EOS 5D~Nikon D700 the a900 was always more noise at high ISO.

OK if i drop down the MP in FF i will get what you actually get with the other competitors with 12 MP FF.

My opinion is if you want to shoot hight ISO reduse the resolution and then you are in the same boat like the others

I figured it would be somewhere around there. 10MP is still perfectly usable, so I don't really see too much cause for concern about "loosing the telephoto." I don't typically shoot above ISO 400, and on occasion 800, so the high ISO noise isn't really an issue for me.
