Sony SEL 55mm f/1.8 T* ZA Sonnar full-frame prime lens combines fast f/1.8 aperture with Carl Zeiss optical quality. Suitable for portraits, events, nature, and night shooting. High-performance Zeiss optics deliver excellent resolution, while a dust- and moisture-resistant body supports outdoor use. ZEISS T* coating reduces internal reflections to minimize flare and ghosting. A 9-blade circular diaphragm provides natural bokeh. Aspherical elements maintain contrast wide open and reduce distortion. Internal focusing keeps the barrel from extending, improves AF response, and reduces minimum focusing distance. Note: on APS-C cameras, the 35mm-equivalent focal length is 82.5 mm. Included: Sony SEL 55mm f/1.8 ZA Sonnar lens, front and rear caps, 49 mm UV filter, lens hood, transport pouch.
