This issue of sensor size, pixel count, pixel size,and their effects re: noise and sensitivity got my little brain racing. What if.... someone like Fuji built a full frame 4X5 digital back using the latest sensor technology, but instead of cramming a zillion pixels, limited it to, say, a reasonable 12 (HUGE)mega pixels? Would that not create not only the "quietest" camera in the world but also the fastest (due to incredibly high maximum ISO and the potential of an integrated electronic "shutter")? In theory it should not cost much, as making large pixels should be easier than tiny ones.Would this not hail the return of the  "press  camera"?!

Silly mental ramblings, I know.

Possibly because some of them take brilliant pictures..  Some have very
good image 'colour fidelity' - some have better UV and IR sensitivity than
the current crop of cameras, all good reasons..

..and then there's this

and thinking further, a 3Mp camera yeilds a print of 5x7 inch at full res
- to double this and go to 10 x 14" you need a 12.6Mp camera.  See, that's
a huge leap up to simply double the print size in linear length, so
stepping up from a 3 to a 4/5/6/8 Mp camera usually involves a substantial
investment for not a huge benefit in image size.  Why make a jump from a 3
megapixel camera to a 6 when all you get is a mere 30% linear length
increase in final image size  ?

an answer here perhaps

personally I feel the same as Ken does when he writes on the link at the
bottom of the page above "I use both digital and film cameras all the time.
They each serve a different purpose"
