Legendary Zeiss Planar 50mm f/1.4 for Contax/Yashica mount with T* coating — a definitive fifty.
The Carl Zeiss Planar 50mm f/1.4 AEJ is the flagship standard lens for the Contax/Yashica SLR mount system. The AEJ designation indicates it was manufactured by Kyocera in Japan to Carl Zeiss optical specifications, combining Zeiss design excellence with Japanese manufacturing precision to deliver an outstanding fast standard lens.
Optical quality is exceptional with the Planar double-Gauss design delivering the three-dimensional rendering and microcontrast that Zeiss lenses are celebrated for. Wide open at f/1.4, the lens produces beautiful bokeh with smooth transitions. The T* multi-coating provides outstanding flare resistance and rich, saturated colour rendition.
Build quality is superb with an all-metal barrel, beautifully damped focusing ring, and the precise mechanical quality that defines Contax/Yashica-mount Zeiss lenses. The lens feels luxurious to operate, with a tactile quality that reflects the premium positioning of the Contax system within the photography marketplace.
Highly sought after on the used market, the Zeiss Planar 50mm f/1.4 C/Y is considered one of the finest 50mm lenses ever made. It adapts beautifully to modern mirrorless cameras where the Zeiss rendering qualities shine. For photographers valuing optical character and build quality above autofocus convenience, it remains a definitive choice.
