Originally posted by Tanzer It might make more sense for someone to develop a focal length reducer to go from K-mount to Q-mount, given that K-mount lenses are so cheap and plentiful. On the other hand, K-mount bodies are still in production and relatively cheap compared to other bodies in the industry/market, and the Q sensor/body doesn't bring anything new to the table, so I can't see why anyone would actually buy such a beast. Those who buy the Pentax K-to-Q adapter are doing it for the 5x crop factor.
Perhaps for video. Smaller sensors generally support faster frame rates and less rolling shutter. And a focal length reduction of 5x would collect so much more light than the Q 01 prime.
The pixel density of the Q added with the degradation of the converter would probably no result in too nice results.
My guess....
Normal viewing would probably be ok though
