Originally posted by Wheatfield I have compared (largish 13x19 inch) prints made with the K3 to prints made with the K1, and yes, there is a very obvious difference. The larger format renders things very differently. Granted, I didn't use the same lenses, my comparison would have been done using the K3 with the FA 31/1.8, and the K1 with the A50/1.2.
I wonder how much of that is down to having a greater resolution for the field of view at the same reproduction size, though... The K-1 has a 36MP sensor vs the K-3 with its 24MP sensor. For the same field of view on each camera, the K-1 is capturing more detail because of the sensor resolution - agreed? But if you look at, say, the Nikon D750 with its larger-real-estate 24MP sensor, at base ISO the detail captured (judging by DPR's studio comparison tool) near the frame centre (where most lenses do OK) is comparable to the smaller-real-estate-sensor K-3. This largely mirrors my own findings, where shots from my 24MP Hasselblad HV and Sony A7II are more-or-less equivalent in detail to my K-3 for the same field of view and reproduction sizes. At least, that's my perception, after several years of use... I haven't carried out clinical tests to confirm.
Not trying to argue the point with you, Bill... I'm just raising the possibility that resolution might be a significant factor too, rather than simply real-estate.
Originally posted by Wheatfield If the more real estate argument doesn't hold true in the digital age, why are we still using cameras rather than cell phones when we want top quality?
I think the point here is, a cell phone camera sensor is typically tiny when compared to any enthusiast or professional format. The difference between, say, APS-C and full frame is considerably less. There's a difference, for sure... but it's nothing like as big. This is why, for instance, some folks opine that the K-1 is close enough to the 645Z - with its larger sensor - that clear justification for the 645Z might be difficult for some users...
