|Don’t ask why Yongnuo decided to showcase a full-frame E-mount lens on an APS-C camera body…our guess is as good as yours.|
Chinese accessory and lens manufacturer Yongnuo has announced the release of a new 35mm F2 autofocus lens for full-frame Sony cameras.
The new lens is constructed of nine elements in eight groups, including one low-dispersion element and one aspherical element. The lens also features what Yongnuo calls a ‘nano-multilayer coating,’ but doesn’t specify what elements this coating is applied to.
The 35mm F2 has an aperture range of F2-F16, uses a seven-blade aperture diaphragm and has a minimum focusing distance of ‘about’ 35cm (13.7”). Its autofocus is driven by a digitally-controlled stepping motor (DSM) and an onboard USB-C port will allow for firmware updates, should Yongnuo release any to improve function or compatibility.

While constructed mostly of plastic, the lens features metal bayonet mounts and uses gold-plated contacts, which transmit, in addition to data for autofocus and aperture control, EXIF data. Also present is a switch for turning on and off autofocus, as well as a Function (Fn) button that can be customized to perform a certain action or bring up a certain menu.
