Originally posted by Lampo Hmmm, with 24 MP you will need quite an expensive lens to really use the potential of that sensor. I am not convinced an entry-level buyer will do that, most people buy a DSLR with two kit lenses and that is it. Another potential flaw is the big memory card needed, although with jpeg that will not be the biggest problem.
My daughter has the NEX-7, and she filled 2 16GB cards with RAW files in a couple of days recently, but they're not expensive anymore, so the bigger problem is actually hard disk and backup space.
About the expensive lens: Not so sure about that, even the Sony 18-55 lens is sharp enough in the center area to allow for some serious cropping with the 24mp sensor.
