Considering its pairing with mirrorless cameras, TAMRON pursued a compact size that allows handheld shooting while developing the 150-500mm F5-6.7. With a length of 209.6mm (8.3 in) and maximum diameter of 93mm, the 150-500mm F5-6.7 is astonishingly compact for a 500mm-class ultra-telephoto zoom lens built for use on full-frame mirrorless cameras. Even when extended to the 500mm telephoto end, the lens has a suppressed length of around 283mm (11.1 in). Another distinctive feature is that the arc of rotation of the zoom ring is small—only 75°—which enables swift adjustment to the desired focal length with minimal movement.
