With this camera we have two options for what they will deliver as entry level:
1. Cheaper than 5D2 and worse than 5D2 (same AF, cheaper/rebel like build).
2. Same price as 5D2 and slightly improved in some areas and worse in others to balance it out (do not expect a good AF system, it might be improved but I would expect equal to but probably less than 7D quality - the cannot canibalise the sales of the 5D3).
Can someone tell me as a potential purchaser of the t4i when and if it comes out what benefits there would be to waiting for the entry level full frame
Advantages of FF: Better image quality, ISO is cleaner and better at the same levels.
Disadvantages: Can't use EF-S lenses. Less "reach" for getting more pixels in the centre of your lens (which is good for wildlife/sport).
