The Sigma has the look of the classic 15mm diagonal fisheye and the Canon nearly the field of view of the classic 100mm macro lenses. Here are some samples made with the 60mm macro lens yesterday morning.
All images are processed from three bracketed files, +/- 1 EV, with Canon's DPP software. Exposure information in the captions are for the normally exposed file. Bracketing is achieved in aperture priority mode by changing the shutter speed. So, the underexposed file will have a shutter speed half as long and the overexposed file will have a shutter speed twice as long as the normally exposed file.

Obviously, with shutter speeds as long as 6 seconds, a tripod and remote release was essential for the above images. Macro lenses are also good for other types of photography, however. This lens makes a particularly nice portrait lens, for instance, and can also be used for landscapes.
The image below was able to be successfully bracketed without a tripod due to faster shutter speeds because of the brightness of the scene and the 8 frames per second shooting speed of the 7D which limits camera movement between shots.
