Sigma 8mm lens on Canon 5DII, Seacam housing
Today we are wrapping up my Digital Master class in Key Largo. Great diving all week and a wonderful bunch of students to dive with. My daughter Alexa even came out on the boat for a few days, and you'll see her in the UW photos posted here.
One of the very nice things about this class is that the diving is so easy, and there are soooo many fish, that it is easy to experiment and still be productive. Earlier in the week I tried out the new Canon 17mm tilt-shift lens, and today I shot some circular fisheyes with the Sigma 8mm.
Of course, for it to be truly circular, it needs to be a full frame digital camera. It was designed for film cameras after all, so a cropped sensor camera doesn't do a good job. But, mounted on my Canon 5DII, it provided an interesting perspective. I had to take the removable sunshades off the Seacam superdome, so the shade would not vignette, but that is a 2 minute fix. Just remove 6 allen screws.
