One effect I like with the Lensbaby Fisheye optic is how it can turn a back alley wall of graffiti into an image that looks like one of the marbles I used to play with as a young boy.
Nikon D7100, Lensbaby Muse with Fisheye optic
This week my Lensbaby Fisheye optic arrived. Inserted in my Lensbaby muse assembly, it requires focussing by squeezing on the bellows, making for a bit of a challenge, but it is a lot of fun! This morning I tried it out at Sugar Beach here in Toronto ( a surrealistic location if you ask me), and I love what the exaggerated perspective does at this location!
