This is a basically brand new set of Anamorphic MFT mount lenses. They are very well made and am selling because I sold my 4k BMPCC cameras. All lenses are optically and mechanically perfect. Price is less than 1/2 of new. Enjoy creating true anamorphic imagery on your MFT mount camera with the Sirui 1.33x Anamorphic Lens Set. It features 24, 35, 50, and 75mm anamorphic lenses that cover MFT and APS-C sized-sensors, and which have a de-squeezed aspect ratio of 2.41:1. In addition to using the lenses to create wide-screen imagery on your sensor, the lenses help create recognizable anamorphic artifacts such as oval out-of-focus specular highlights and anamorphic streaks and flares often absent when using anamorphic adapters. Coatings on the lenses allow the lenses to flare without allowing the flares to overwhelm your image. This kit includes a case to carry the four lenses in. Sirui 24mm f/2.8 Anamorphic 1.33x Lens (MFT Mount) This 24mm f/2.8 Anamorphic 1.33x Lens from Sirui, in an MFT mount, brings a wide-angle feel to your anamorphic imagery, in addition to the extra width provided by the anamorphic process. Designed for MFT/APS-C cameras with an MFT mount, the lens increases the horizontal FOV by 33% compared with traditional 24mm APS-C lenses. After de-squeezing, the captured image is displayed in a 2.4:1 format in a 16:9 setting. Lightweight and portable, the f/2.8 lens is designed with an aluminum housing and features optics with multilayer nano coatings. Made with renowned Schott optical glass lens elements, it produces rectangular aspect ratios, long horizontal lens flares, and oval bokeh. One of the exciting features of this lens is the close focus distance of just under 2', allowing you to get close focus for creative effects. Focus scales marked in both feet and meters makes this well suited for users around the world, and the 72mm filter thread is a popular filter size for adding filters to your lens.
