The _Sony FE 135mm f/1.8 GM _is a new prime _lens_ for full-frame Sony mirrorless cameras that’s designed to deliver the ultimate bokeh. The mid telephoto prime lens features 13 elements in 10 groups including a recently developed, extremely precise XA (extreme aspherical) element that reduces aberration and increases resolution, as well as Super ED (extra-low dispersion) and ED elements.
It has a near-circular 11 blade diaphragm, the most ever used in an Alpha lens, which creates a very attractive blur to the out-of-focus areas of the image, Sony’s Nano AR Coating to reduce flare and ghosting, a fluorine coated front element, and it’s also dust and moisture resistant.
