I've been shopping around for a Digital SLR (I'm retiring my 35 mm Pentax Z1P). One salesman stated to me there is no difference between 6 megapixel and 8 megapixel. You only see a diff. between 6mp and 10 mp. The largest print I've made is 16 X 20 inches and a 12 X 36 inches. Using a cheap 5 megapixel Samsung compact camera. The 12 X 36 was actually three photo's mergered together to make the panoramic shot. Does anyone have experience with printing up larger prints from digital cameras.
