So thanks to Ross, I have just taken ownership of a Pentax Q10. It's so dinky! I was very surprised at how small it was (I shouldn't have been if I had done my research better); it looked much bigger in the photos.
While the K-50 is my main camera, I wanted something smaller as in the summer time I like to head out on long scenic walks and the 50 is a bit too cumbersome to carry a long way. I also wanted something that I could have full control over (manual controls, etc, etc.), and also shoot in raw.
The Q10 also has the advantage of being more discreet, which will come in handy when shooting in crowded places. This camera ticks the above boxes even if it isn't the latest in gadgetry.
I haven't had much of a chance to play with it yet but the few inside shots I took this evening turned out okay, so I'm happy. I've just begun another photography course so will have a chance to play with it this weekend while I complete my assignment
PS: thanks Ross
