Hi,
I have always produced a print. This, from the film days, where I didn't want to shoot positive and stick the slides into a projector.
135 small format didn't make as nice an 8x10 to hang on the wall or stick in a coffee table book as 645 medium format did.
Same was true for digital. The APS-C sensor cameras didn't do as well as the APS-H ones. Meaning 2-3 MP v 6 MP. Later I wanted larger than 8x10 and moved to MF again as that offered 16 MP for a better 11x14 print. Keep in mind there are always pixels lost from the shooting aspect ratio to the printed one.
Once I picked up a Nikon Df, with those 16 MP, I passed on most of the other cameras. I figured I could do just fine with the printer I had feeding it from the Df. Until I wanted to print larger once again. Now at 16x20. So I looked around and chose a 40 MP MF.
But that's back to a Kodak CCD and limitations over the newer CMOS from Sony. Now I can say that for where I am now with printing, a 50 MP would do well. Seemingly. However, I don't care for the aliasing it has. And that means looking at the 100 MP sensor instead.
So, that's it in a nutshell.
