Everyone keeps saying that the price of full frame sensor?s will go down. I say who cares! I like my 20D sensor, I don?t want a large sensor. I like the extra mm?s I get with my zoom! Also, they will surely come out with a small sensor that has 10 MP maybe even 15MP... And I bet that will happen fasters then the larger sensors coming down in price! I guess only time will tell?
