Very cool, compact little anamorphic lens. It has nice flares and a very nice aesthetic without any hassle of a normal anamoprhic. This one is for the sony e mount cameras, I have personally used it on a sony a7r2, (it covers a super 35 sensor) in crop mode and it is a great pairing. I will supply a uv filter ( for protection ) and a (nd.6) for convenience. Here is the company description........... Give your movies a cinematic feel with an anamorphic lens! Classic films such as Blade Runner, Alien and Gladiator all have one thing in common. In addition to film producer Ridley Scott, they also have a technique that brings them together - an anamorphic lens. This has previously been a somewhat complicated and above all expensive solution, but with Sirui's Anamorphic Lens 1.33x it will be both easier and cheaper than before to give your films a truly cinematic feel. - Give your videos that classic movie look - Creates an aspect ratio of 2.4:1 - Horizontal flares that give a Sci-Fi feel - Nice oval shape bokeh similar to the one in movies - Fits micro 4/3 mount - 13 pieces of lens elements in 9 groups *Make cinematic films with your own camera* With the Siriu 35mm f/1.8 anamorphic lens, you have the opportunity to film with the same effects you see in blockbusters. The oval and soft bokeh in the background is created by just one anamorphic lens. Another effect you get with this lens is the characteristic horizontal flares recognizable from famous Sci-Fi films. *Get the magical 2.4:1 ratio in the movie* The Siriu 35mm f/1.8 anamorphic lens expands your horizontal field of view by 33% compared to a traditional lens. In post-processing, you will then "de-squeeza" your film or images, giving you the cinematic aspect ratio of 2.4:1. It is this post-processing that gives your bokeh that oval look so that the round shapes are drawn out. Compatible with sony E mount.
