Yongnuo has announced its first lens for the Sony mirrorless cameras. The Chinese budget accessory specialist already products a number of highly-affordable prime lenses for Nikon and Canon DSLRs... but now has produced a 50mm f/1.8 'nifty fifty' lens for use on Sony E-mount APS-C-format cameras.
The Yongnuo YN50mm F1.8S DA DSM is designed to be used with the popular Sony A6000 mirrorless camera, and other more recent Alpha A6*** series models. As such the effective focal length becomes a 75mm, creating a lens that will be ideal for portraiture.
Unlike other low-cost options, the Yongnuo prime offers autofocus operation, using a digital stepping motor (DSM) that promises "fast start and stop response, high focusing accuracy and quieter focusing action".
The lens is constructed from eight elements in seven groups, with a seven-bladed diaphragm, and weighs just 146g (5.1 ounces).
