Ultra-wide lenses are critical in underwater photography for getting close to your subject. Reducing the amount of water in front of our lens has a dramatic impact on color and clarity in the resulting images.
Fisheye lenses are by far the most popular choice for wide angle underwater photographers due to their exceptional sharpness behind a dome port. But one thing surface photographers fear when picking up a fisheye is distortion. We’ve seen the fisheye images of buildings where skyscrapers have scoliosis. You may be surprised that the distortion isn’t as bad as you think it will be… and that it just may look more natural than a rectilinear lens underwater!
Ambassador Bill Hawthorne set up an underwater scene in the Florida Springs to compare two of the best ultra-wide lenses on the market today: the Canon EF 8-15mm f/4L Fisheye and the rectilinear Canon RF 10-20mm f/4L IS STM. You may be surprised by the results!
Scroll down for image comparisons at both large and small apertures.

Conclusions
So which do you prefer? The classic EF 8-15mm still wins in our book in terms of angle of coverage, edge sharpness, and - incredibly - less apparent distortion around the edges of the frame. The inventor of the term “fisheye lens” was making a lens that could capture “how a fish sees,” so perhaps we shouldn’t be surprised that they can actually deliver a more natural look underwater depending on the scene and subject matter.
Thinking of trying a fisheye lens? Get 'em while they last!
