Originally posted by audiobomber Here's an example, comparing the Nikkor 50mm f1.8G on a 12mp APS-C D90 body, a 16mp APS-C D7000 body and a 16mp FF D3X body:
Not exactly a clear-cut comparison - since all of those cameras have Bayer AA filters. Also the last time I looked the Nikon D3X had a 24.5Mp sensor. The only two cameras that would be reasonably fair to compare would be the D90 and D700 - which Dxo points out to there being a 1Mp difference in image quality,
1 frigging megapixel which is a rather trivial amount of improvement with the same lens
- let me put it into perspective: when comparing the K5IIs and K5II you will see a bigger difference than 1Mp. Though having said that there are many other areas that improve by using a FX format sensor: shallower DOF, better low light capability, bigger viewfinder, lenses are easier to design...etc,etc, so on and so forth. i'm all for pentax making a FX format DSLR, but I don't think they should abandon APS-C format either.
