I recently despaired of getting another camera for my wife, despite my certainty that a yellow K-01 would prove irresistible. We have similar Lumix G1s so that would be the vehicle that allows us to shoot 'identical' images, so she would learn to see what I see on the same subject. The G1 is a great camera with some nice features, and it's an ideal learning tool, but my wife's health is such that even micro-43 is pretty bulky for her use.
Talented too, by the way. Its backlit 12Mpx sensor can do quite well to iso1600 or a bit more, and it has raw abilities for personalized processing for sharpness, noise and everything (unlike jpg with its fine but compressed images that don't decompress the same twice). I really liked the Fuji F550 (until it hit the pavement, hard) for its 1/2" sensor with raw shooting, so part of this will be familiar to me. Many things, actually - the menu system is almost a mirror copy of the larger Pentaxi in my collection, so my learning curve will likely be quite short!
So the Pentax Trifecta is complete - do not hold your breath for the Grand Slam, as the $10k± 645D will not be in my financial league for the foreseeable future. Plus it's kinda big.
Oh hey, did I mention the adapter to allow K-mount lenses to work with the Q?
That DA40 pancake lens just mutated into a 230mm telephoto... so they tell me.
