When the Q was released I, as probably many others, was fascinated by the "cuteness-factor" plus the very small pixel pitch of 0.0015mm and I was impressed by the many functions, RICOH/PENTAX had managed to squeeze into this tiny body. Yet, I was also sure that I would never buy into this system with its tiny sensor and lack of a proper viewfinder.
But then came the Pentax Adapter Q for K-mount Lens, and with my interest in macro and astro photography I began playing with the thought, that maybe someday......
Suffice to say, I have now pulled some triggers and purchased:
•A used Q10 (like new - 4500 actuations) found at a very reasonable price in Germany, Maxema-shop
•A brand new Pentax Adapter Q for K-mount Lens adapter found at SRS Microsystems, UK - I think, I got their last one?
•A Q to C-mount adapter found on eBay.co.uk
•A C-mount to 1.25" draw tube adapter also found on eBay.co.uk
The latter two adapters converts my Q10 to a light-weight high resolution lunar and planetary camera for my vintage Vixen R100-L Newtonian reflector. So now, let the fun begin.
And boy, isn't it just fun to try out one's old and new lenses on a 1/2.3" sensor with 0.0015mm pixel size!!! Here are just some initial results, (click on images to see larger versions):
Barometer: Tamron Adaptall-2 24mm f/2.5 lens (Model 01B)
Metal Works next to my work place: Cosina Cosinon-W 35mm f/2.8
Gable Clock at Farum Train Station: smc Pentax-FA 1:1.4 50mm
Pincushion: smc Pentax-DFA 1:2.8 100mm WR macro lens
My blinds in evening sunshine: smc Pentax-DA 1:3.5-5.6 18-135mm WR @ 135mm
Quarter Moon: smc Pentax-DA* 1:2.8 200mm
Now, lunar images can be hard to evaluate, because they are mostly cropped. The above is the full (but downsized) Q10 frame and to put things in perspective, here's the same image cropped and downsized with a K-3 photo inserted taken with the same lens on the same night. The image below links to a non-resized 100% crop:

Sensor size is one thing. Pixel size is yet another important factor in some applications. And hereby over for now; my telescope needs to be dusted off......
