This fisheye is really interesting. I really have not seen much work with it. I was skeptical about a good use for it. Ken Rockwell has said that wideangle lenses are not for "getting it all in" but to place the person who sees the photo right in the shot. You have really done that here. I have been to Yosemite but it was before I had my Nikon 12-24mm. I got to get back there. This is a great pic. Thanks for posting it for us to see.
