i currently am still using my Pentax K20D, and while I've been thinking about getting a new body recently, perhaps even full-frame, I decided for now just to get a new walk around weather sealed lens. Most of my glass is legacy and not weather sealed, and I find I haven't been shooting as much recently due to that while on my travels. Am getting it through B&H.
