For those who shoot a lot of telephoto but little wide angle the APS sized chip has an advantage with it's smaller AOV. 6 MP is proving adequate for many consumers. Assuming that a FF sensor will have significantly more MP then an APS sized chip, the APS sized chip would have faster write time to the media card and would store more images at any given resolution. The full frame would have a higher resolution and better enlargeability all other things being equal. It strikes me as not dissimilar to buying a car. I can get the model with a 4 cyl or 6 cyl. The 4 will give me better gas mileage, the 6 better performance. I make the decision based on my needs. Butch
