Glad it's working out for you, love the lizard shot, it's like he's a king and wearing a cape.
I'm coming up on 1000 shots on mine, and really liking it.
My wife is liking the kit 18-55/full auto/green mode mostly at this point, and I'm really liking the SMC-A 70-210mm F/4 and the 50mm f/1.7 SMC-A. It would be great if the K5 were able to detect/record the focal length on the older lenses, just to show where most of my images wind up being shot. I've been pleasantly surprised at how well the K5 with the 70-210 has taken some nice sunset and low light outdoor shots, but can see something like the 55-300 in our future, as I've been 'banging both ends' within the same hour with the 70-210mm, wanting just a bit wider/shorter focal length, as well as more zoom. It's a tough call, without unlimited LBA funds - I may wind up going to something like a faster wide to normal lens to replace the kit lens, then saving some $$ for a faster zoom with more reach.
Either way, I'm pretty happy with the pictures taken to date, and glad you're enjoying yours!
