I think I'm pretty close to buying a k-x and pretty excited about a new camera after taking so many pictures with a Fuji S5100 (4 MP bought in 2004). I've taken a lot of great pictures but it's time to learn how to take even better pictures.
I have a 1 month trip thru SE Asia planned this winter that will take the road less traveled (in addition to seeing the big sites like Angkor Wat and halong bay). But the big trip I have planned is Nepal and Tibet in Spring 2012. I'm planning on doing at least 2 long treks in Nepal and the AA batteries are essential for this imo. The nice selection of primes is also nice for backpacking.
Lens roadmap
DA15mm - the dream since I always want to get wider (going to need to save for this one)
maybe some manual focus lenses between 28mm and 70mm
possibly no zooms other than the kit lens
the DA40mm seems like a good value and companion to the DA15mm
But I won't be buying lenses in a hurry. I still have a lot to learn.
