Opteka Fisheye Adapter

After hemming and hawing about a fisheye-type lens, I finally purchased an inexpensive fisheye adapter. The adapter screws on to an existing lens and will allow me to play a bit without a huge investment.

I purchased the Opteka 0.20x Fisheye adapter. I also purchased a 67mm to 52mm step down ring, which allows me to use my 18-70mm f/3.5-4.5 lens.


View of the glass on the adapter:


The 0.20x means the starting focal length is multiplied by 0.2 for the final focal length. Wider means more distortion, and I've shot all these photos at 18mm. I really like the effect and can't wait to experiment with it more.
