Overall, the TL500 has an attractive, functional design that I like. But I did run into a few frustrating accident-prone control locations. One is the jog dial on the grip that controls exposure compensation, shutter speed, aperture, and so on (depending upon mode). It's hard to differentiate the feel of the wheel from the grip. That means it's hard to find when you want it, but it's also hard to tell if you've accidentally pressed or turned it. I ended up accidentally shooting a group of photos with the exposure compensation bumped up because of it.
