Sonnar* T* 135 mm f/1.8 ZA
Telephoto Prime Lens for A-mount Cameras
The Sonnar* T* 135 mm f/1.8 Zeiss lens from Sony is designed as a medium telephoto prime for full-frame A-mount cameras, especially suitable for portraiture given its 135 mm focal length. Used on a APS-C camera, this lens provides an full-frame equivalent focal length of 202.5 mm. The bright f/1.8 maximum aperture enables working in low light and works hand in hand with the 9-blade circular aperture to benefit shallow depth of field techniques, providing sharp foregrounds that are contrastedby smooth and pleasant bokehs. The 11 elements in 8 groups optical design includes two ED (Extra-low Dispersion) elements to effectively suppress chromatic aberration for sharp and consistent contrast throught the aperture range. Application of the ZEISS* T* coating to the glass elements contributes to colour accuracy and contrast by suppressing reflections and reducing flare and ghosting. Additionally, the built-in SteadyShot Image Stabilisation system minimises camera shake appearance for handheld operation in a variety of shooting situations.
