Realize the full potential of your full-frame Canon EF-Mount glass on your APS-C and Super35 format Sony E-Mount cameras with this Metabones Canon EF to Sony E-Mount T Speed Booster ULTRA II 0.71x. Utilizing advanced optics, this adapter will increase the apparent angle of view of your full-frame lens by 0.71x, effectively combating the crop factor of an APS-C camera. This also increases the apparent sharpness of your image while also increasing the maximum aperture by 1 stop, making your full-frame lens look as if it were mounted on a full-frame camera.nnFurther improving on previous generations of Smart Adapters, this fifth-generation model now features a rubber gasket to protect the camera’s mount from dust and moisture, offers a status notification LED light to check operation modes, and provides a dedicated switch that controls in-body image stabilization of select cameras. Also, this version is compatible with the Sony PXW-FS7 Mark II video camera.nnThis adapter is equipped with numerous capabilities thanks to the use of a high-performance 32-bit processor. The features include support for both phase-detect and contrast-detect AF systems, as well as the ability to control the aperture from the camera body. Smooth iris effects are possible on select lenses, and 5-axis stabilization is available thanks to communication of distance information with supported lenses. Also, it features a programmable function button, enables electronic (focus-by-wire) manual focusing, transmits EXIF data to the camera, and works with in-lens image stabilization. Additionally, distance and zoom is displayed on certain camcorders and mirrorless cameras, auto magnify can be enabled, and it can automatically switch into APS-C mode, depending on the lens used.nnBeyond electronic communication, the adapter has many physical advantages as well, such as a black felt flocking on the inside of the adapter that prevents reflections. For larger lenses, there is a removable Arca-type compatible tripod foot with a 1/4″-20 thread on the base.
Allows users to adapt a full-frame Canon EF-Mount lens to an APS-C/Super35 Sony E-Mount camera, or a full-frame camera in APS-C mode.
Advanced 5-element in 4-group optical construction uses ultra-high index tantalum-based glass, increasing the angle of view of a full-frame lens by 0.71x, and the maximum aperture by one stop. This effectively compensates for the 1.5x crop factor of APS-C cameras and provides an image like that of a full-frame lens on a full-frame camera.
Electronic contacts permit transmission of data between the lens and camera enabling autofocus, auto exposure, image stabilization, aperture control from the camera body, saving EXIF information, and more.
