Zeiss is rumored to announce a new 135mm f/1.8 lens for Sony A-mount cameras at the Photokina 2014, replacing the current model with the addition of SSM focus system.
One of the A-mount lenses that is receiving a lot of positive reviews from photographers is the Zeiss Sonnar T* 135mm f/1.8 model. Sony A-mount camera owners are praising the sharpness and the overall image quality of this product, so one could say that a replacement is not necessary. However, inside sources are claiming that a new Zeiss 135mm f/1.8 SSM lens will be unveiled at the Photokina 2014.
New Zeiss 135mm f/1.8 SSM lens for Sony A-mount cameras coming at Photokina 2014
A lot of lenses are expected to be introduced by Sony and Zeiss for A-mount and E-mount cameras at the world’s largest digital imaging event. The show will open its doors in mid-September in Germany and should also allow users to see the FE 16-35mm f/4 ZA OSS in action, after being announced by Sony at the beginning of May
The only major change when compared to the current Zeiss Sonnar T* 135mm f/1.8 version consists of the addition of a SSM system. SSM stands for SuperSonic Motor and it represents a silent ultrasonic motor that is built into the lens.
SSM focusing should be smoother and more silent when compared to the SAM system that stands for Smooth Autofocus Motor, which is a cheaper focus system.
It is said that the new Zeiss 135mm f/1.8 SSM lens will not undergo any optical design changes when compared to the current Zeiss Sonnar T* 135mm f/1.8 ZA lens. Nevertheless, we should wait for the Photokina 2014 before betting all our money on this rumor, so take it with a pinch of salt.
