Love the fisheye effect? Turn to the Canon EF 15mm fisheye lens, which offers an ultra-wide 180-degree angle of view for capturing scenes well beyond your natural field of vision. As with all fisheye lenses, the 15mm provides a ton of unique and interesting effects, with a minimum focusing distance of 8 inches giving new meaning to close-up shots. Best of all, the lens is tack-sharp throughout its entire focus range. The lens--which includes a fixed petal-type hood and a built-in rear filter holder that holds up to three gel filters at once--carries a one-year warranty.
