Carl Zeiss Sonnar T 135mm f1.8 telephoto with wide aperture for amazingly bright telephoto shots.
Superb sharpness with Sony Super SteadyShot system.

35mm focal length, 52.5mm equivalent focal length on APS-C cameras, 56mm equivalent focal length on Canon APS-C cameras.
Equipped with technology including a Hyper Sonic Motor (HSM), floating internal focusing system, SLD and FLD Glass elements..
HSM ensures quiet, high speed, accurate autofocusing while the floating focusing system allows for superior optical performance with subjects at a closer shooting distance..
SLD glass elements along with the FLD glass elements, which are equal to fluorite, help correct both axial and chromatic aberration..
COMPATIBILITY: Can be used on all Nikon APS-C and full frame cameras including D7500, D7200, D7100, D5600, D5500, D5300, D5200, D5100, D5000, D3400, D3300, D3200, D3100. D3000, Df, D5, D4, D3, D850, D810, D800, D750, D700, D610, D500, D90, D60 and D40..

Nano Crystal Coating System (NCS) for increased light transmission and reduced internal reflections.
Fast F2.0 maximum Aperture + close-focusing to 9.5 inches = maximum versatility in all shooting conditions.
