Ok, so apparently I was supposed to post the make and model of the new camera not just assume that you people would look at the EXIF data…
The camera is an Olympus E-PL1.
The lens is Panasonic’s 20mm fixed focal length micro-four thirds lens.
For kicks I took the comparison photos between my new camera and old: http://picasaweb.google.com/lh/photo/MkMiFwZSZbsGaEPk8tkSVg?feat=directlink
They are quite close to the same size (partly because I choose the pancake lens). There is a weight difference, though.
As to why I picked this camera/lens:
I wanted a camera that got distinctly better image quality than my old camera. Within the compacts, there didn’t seem to be anything that really was good enough. The DSLRs are all too big for ease of use while skiing and rock climbing. (I didn’t try to keep kayaking as a requirement because that eliminates all cameras.) So I was looking at the small end of the micro-four thirds system cameras — the Olympus E-PL1, Panasonic DMC-GF1 (or two if I wanted to wait until January) — the Sony NEX, and I think there might have been something else that was just announced a week or two ago. Of the E-PL1, the DMC-GF1, and the NEX, the E-PL1 had what appeared to be the best image quality even though the NEX actually has a bigger sensor. The image quality issues in the DMC-GF1 were consistent with other Panasonic cameras, so I didn’t expect the DMC-GF2 to be different.
As for the lens, having upscaled the camera, I basically went hunting for the smallest lens available that I thought I could work with. It has a 35mm equivalent focal length of 40mm. So it’s in a zoom range I use fairly often. As an added bonus (or minus on the pocket book), it is a higher quality lens than the kit lens. We are still considering getting a second lens with good zoom, but I want to see how I end up using the camera and if bulk will be an issue.
