Introduction
Fisheye lenses offer the widest field of view among all lenses. A non-circular fisheye provides a 180° diagonal field of view, something no rectilinear lens can remotely achieve (a 14mm lens gives you 114°, a 10mm lens 130°, and a 9mm 135°). Fisheye lenses are especially useful when you want to capture as much as possible in tight, confined spaces or wide, open areas. They also offer a unique and exciting perspective that can be creatively exploited without restrictions.
If used skillfully, fisheye lenses can produce images that look relatively normal in many scenarios, though not all. The TTArtisan 7.5mm is a non-circular fisheye lens designed for APS-C cameras, but it can also be mounted on full-frame cameras, where it produces circular fisheye images (180° both diagonally, horizontally, and vertically). Let’s take a closer look!
I tested the lenses on a 46 Mp Nikon Z7ii (Sample images were taken with a Nikon Zf , Nikon Z6, and Sony A7 III)
