Regarded as one of the best telephoto primes for portraits, Sony's Sonnar T* 135mm f/1.8 ZA Lens boasts one of the fastest apertures available at this focal length as well as outstanding resolving power across the frame. Designed for full-frame A-mount cameras and featuring an f/1.8 along with a nine-blade circular diaphragm, this lens is able to capture photographs with exceptionally shallow depth of field. Also, it uses two extra-low dispersion elements in the optical design as well as Zeiss' outstanding T* anti-reflective coating to combat aberrations and minimize flare and ghosting, respectively, in order to create crisp, clean imagery.
For natural and intuitive handling, the lens is equipped with various technologies, including an Auto Clutch mechanism that prevents the focusing ring from rotating when autofocusing. It also offers a minimum focus distance of 2.4', enabling a magnification of 0.25x for close-up photos. Additionally, it is equipped with a focus hold button for rapid control over the lens during shooting.
