Hi jeff, I`m really not sure mate, the technology appears to be moving at an incredible rate, I`m sure the old Nikon film camras didnt move this fast, you can now pick up a sigma 14MPS for £600, its not just about MPS of course but it helps, I predict we`ll see 20 plus MPS in the next 10 years as standard, I think whatever you buy jeff alway be [repared to maybe have to change it a few years down the line.
