One serious problem with ‘fisheye’ photos is the difficulty of keeping unwanted elements out of the eventual image. Since I’ve had this lens, I have taken numerous closeup pictures of fingers, thumbs, and camera straps, but I am now getting the hang of it.
The lens is still fun at the moment. The Lloyd’s Building seemed to be crying out for attention when on a recent walk in London. The only unwanted element in this one was a car parked in the lower right. The clone tool fixed this!
