Canon has designed a pair of RF-mount catadioptric telephoto lenses that it says successfully corrects for field curvature while still being small, lightweight, and have a large aperture: a 300mm f/2.3 and a 400mm f/5.
Tokina will make its SZ 300mm PRO Reflex f/7.1, SZ 600mm PRO Reflex f/8, and SZ 900mm PRO Reflex f/11 reflex lenses available on February 3, 2023.
Kenko Tokina has launched an IndieGoGo campaign for its three compact super-telephoto APS-C prime lenses: the 300mm f/7.1, 600mm f/8, and 900mm f/11.
Kenko Tokina has announced that the 500mm f/8 mirror lens that it teased last year is finally available and will be available for Canon EF, Sony E, Nikon F, Nikon Z, Fujifilm X, T-mount, and Micro Four Thirds.
