Today I tried something that I've never succeeded at doing right: multiple exposures! It was not something I tried often with film, and for good reason: my cameras never made it easy to do. With the K-7 it was two or three buttons and done. I then cropped it in-camera as well, which I'd never done on a dSLR but had managed with my Casio P505. The result was easy, and quite nice. My wife had been doing some math problems earlier, so I shot her book then her in the kitchen; a quick crop boiled it down to essentials.
Once again, I'm impressed with this camera's abilities.
