Photos taken with a Canon 15mm fisheye lens. This lens can capture a 180 degree angle of view from corner to corner on a camera with a full-frame sensor. Many photographers are of the opinion that a fisheye lens is not a serious lens. I think that I would have to agree with them. I got this lens to play with, and in doing so I hope to better understand when it would be appropriate to use this lens. In the mean time I hope you will bear with me as I experiment.
