Yongnuo has announced the YN50mm F1. 8S DA DSM, it’s newest autofocus ‘nifty/thrifty fifty’ lens for Sony E-mount APS-C camera systems. Yongnuo currently offers 50mm F1. 8 lenses for both Canon EF-mount and Nikon F-mount, but this new ‘nifty fifty’ is designed specifically for use with Sony’s a6000 series mirrorless cameras.
The lens is constructed of eight elements in seven groups, including one low-dispersion element to minimize aberrations. Yongnuo says the lens also features a seven-blade aperture diaphragm, gold-plated contacts with a metal bayonet mount and a ‘nanometer multi-layer coating’ to minimize ghosting and flares. The internal autofocus is driven by a digital stepping motor (DSM) and the lens offers an onboard Micro USB port for upgrading the firmware.
The lens doesn’t currently have a price or release date, but considering Yongnuo’s previous lenses sought to undercut the already-affordable ‘nifty fifty’ lenses on the market, you can count on this one coming in very cheap when it hits retailers’ shelves. The lens measures in at 58mm (2. 3") long, 64mm (2. 5") diameter and weighs roughly 146g (5. 15oz).
