Maybe it wouldn't be cheaper then a FF sensor, but maybe that isn't what makes the FF camera's so expensive. It's also about building a system and when more current lenses can perform to their quality on a smaller sensor then a FF then that is where you win the most. I'm thinking off DA40mm, DA70mm, DA*60-250mm. Maybe even the FA series 31mm/43mm/77mm can perform better on a smaller sensor then FF and would make a lot off users very happy.
What about the new DA560mm/f5.6? Would that lens gain IQ from an APS-H over a FF sensor?
But why a custom made, low volume (thus expensive) APS-H sensor when there are FF sensors on the market?
It's risky to bet your future on such an odd format. That's exactly what Olympus did, with the 4/3: going with a slightly smaller sensor, which wasn't cheaper. They also tried to compensate through sheer optical quality. Guess what - 4/3 is dead now.
I would like a K-5 IIs-level (price and features) APS-H (with an excellent sensor) camera, if possible; but I'm afraid it's not. I believe it would rather compete with the entry level FFs, not much cheaper yet "inferior".
No, the DA 560mm (nor any other lens) will not gain any IQ by cropping it in camera (by using a smaller sensor), versus using the full image circle or cropping it in post.
Originally posted by Clavius Strange, as technically the APS-H should be better at wide angle then APS-C. And better at tele then FF. Glass is half empty, or full?
No, it won't be better at tele than FF - since you can crop the FF to APS-H (or smaller) sizes, if you wish.
Originally posted by Clavius LOL! Who says Pentax can't get a APS-H sized sensor cut from the Nokia 808-sensor wafer? (That would be 1080mp.)
If they would do that, they will get a non-functional piece of a wafer with N Nokia 808 sensors
You can't just cut the wafer as you wish.
