Picked up earlier in the week from the parcel drop-off (newspaper kiosk down the street from work): a Canon EF 50mm f/1.4 lens. This is intended for a full-frame camera, so on my APS-C camera it's the equivalent of an 80mm or 85mm lens, but with the added advantage that (if I've understood correctly) there should be even less vignetting than with a lens designed for an APS-C camera.
Here are some pictures I already posted on another forum a couple of days ago, with it mounted with a 13mm extension ring on a Canon EOS 100D.
No image retouching, just resized to 15% and saved at 75% JPEG quality. The first three are at f/1.4, the last at f/2.8. Open the two images side by side, and you see that there is a slightly greater depth of field in the last one.
