Sony SEL55F18Z Sonnar T* FE 55mm f/2.8 ZA Lens

The Sony Sonnar T* FE 55mm f/1.8 ZA Lens is a prime, normal focal length lens featuring a very fast and bright f/1.8 maximum aperture to support working in dimly-lit conditions and for greater control over focus for shallow depth of field imagery. The sophisticated Sonnar optical design enables high resolution and sharpness with optimized low-light shooting capabilities. A Carl Zeiss T* anti-reflective coating has also been applied to lens elements to reduce lens flare and ghosting for improved contrast and color fidelity.

Additionally, a dust- and moisture-resistant construction ensures this lens' use in tough environmental conditions.
