I have an APS-C setup with the 7D and 10-22 and 17-55 2.8. I have considered moving to FF with the recent reduction in prices of the 5DII and the 6D being announced, but here's the dilemma:
1. I am quite happy with the IQ of the 7D up to ISO 1600, but the noise above that is bad. So indoor photography without flash suffers. That is the main reason for my FF considerations.
2. I am aware that if I move to FF, I will have to trade my EF-S lenses for FF equivalents. My lenses will hold their value and I can get the 24-105 and 17-40 without losing any money (cannot afford the 24-70 II). But while the 24-105 is very good lens, I am not so sure about the 17-40. I didn't like the copy I owned (and I used it on a 5DII as well). And, I cannot afford the 16-35 II. Additionally, if I use f/4 after moving to FF- what do I gain over using f/2.8 in APS-C?
3. I did like using the 5DII for the short time I had it and the images were very nice, especially since I almost exclusively use the center AF point, but I do use the high-speed mode a lot on my 7D and I will certainly miss it (and again, cannot afford the 5DIII).
So given these circumstances, is there something I would gain by going FF with a 5DII/6D with a 24-105/17-40 (that offsets my loss of fps) or should I wait until I can afford the 5DIII/24-70II/16-35II? I am sure many of you have gone this route- your advice will be greatly appreciated.
