Review: Laowa 20mm f/4 shift lens. Also - how to use a shift lens.

Detailed review of the Laowa 20mm f/4 shift lens by Keith Cooper. The lens is available in a range of mount options Canon EF and RF, Nikon F and Z, Sony E, Pentax, L, and Fuji G - the RF version is tested here, but the optics are the same for all mounts. The lens is a fully manual shift [only] lens, so no tilt. Keith discusses the lens, how it performs, and has a run through of the many ways lens shift (aka rise and fall) can be used. There is a more detailed written review of the lens, which includes many more sample images at: https://www.northlight-images.co.uk/r...
