EF-E II AF Speed Booster adapter for Canon EF optics on Sony E-Mount

This Viltrox Autofocus SpeedBooster EF-EII adapter allows you to mount a Canon EF Full Frame lens on a Sony E-Mount camera. In doing this, the adapter optics helps maximize the apparent field angle of the connected lens, at the same time providing an increase of a stop for the camera on the lens opening range. If a 35 mm film-intended lens or full-frame camera sensors similar is connected to a sony camera with attack and, it will project a larger image than the camera's APS-C sensor has been designed to accept. Able to capture only the central part of the projected image, the actual field angle of the lens would be reduced, creating a "crop factor" in the camera. This adapter condenses the light from a lens designed for 35 mm films or "Full Frame" cameras and projects it on the APS-C sensor of a Sony E-Mount camera. This allows the APS-C sensor to use more light collection from a connected lens, which effectively reduces the clipping factor making a stop of additional light to the sensor for each of the target's f / stop settings. If a compatible lens includes the Autofocus and the camera-controlled opening functions, this adapter allows you to use these functions. Furthermore, if a lens mounted is able to generate EXIF metadata when used with a directly compatible camera, this adapter is designed to allow saving such information together with the image files generated with a lens combination, a Sony camera compatible with attack And and the adapter. This adapter is built with four lens elements in four groups designed to provide optical clarity and color loyalty, and the lower part of its detachable tripod foot is equipped with 1/4 "-20 accessories thread, allowing the Direct connection to tripods or quick release plates with 1/4" -20 connections. To facilitate firmware update, this adapter also includes a micro-USB port. For Sony cameras compatible with attack and which have phase detection autofocus and contrast, a lever switch to enable autofocus settings with a Canon EF-Mount lens connected is positioned along the side of this adapter. To properly apply a desired auto focus setting, the selection of the lever switch must be made before placing the adapter on the camera. This adapter is compatible with Sony Nex-5C, C3, 5N, F3, 5R, 6, 7, FS700, VG20 and VG900 Sony Alpha A5000-A5100 Sony Alpha A6000- A6600
