Realistically, in terms of details and image quality is there a big jump when going from a 12MP sensor to a 21MP sensor? Any comments from those who have?
These are my personal findings from what I have seen and judged with my own eyes.....
......a 12mp camera such as my own D300's sweet spot print is about A4 at 300dpi
......tested out the D3x Nikon against the Nikon D300 and found linear enlargement at quality only around 30%.....so from 12mp to 24mp at the price it aint worth it...by at quality I mean around 300dpi
.....from a D300 to a 31mp camera linear enlargement at quality is 15cm to the sides extra, so about 45cm approx......
......to get double the linear enlargement at quality compared to a 12mp camera you're talking a 50mp camera.....
a 6x6 Hasselblad etc 120 roll at quality you're looking at around an A4 size before you start to curse the grain.....
a 5" x 4" at quality you're looking at around 635mm at quality
I'm currently shooting some fashion for a retail shop and producing 1m tall prints from a D300 which look great....so remember the viewing distance is a factor in all this.....
