KIPON BAVEYES EF-MFT AF 0.7x mounts Canon EOS EF and EF-S lens, and third-party Sigma, Tamron EF mount lenses onto M4\/3 Micro Four Thirds mirrorless camera especially OM-D series bodies. This adapter, designed by German optics research institution IB\/E OPTICS, can mount full frame lenses onto APS-C frame camera bodies.There are four pieces of optical customized multiple layer coating glasses within the adapter.<\/p>\n
With the optical focal reduction adapter, when the full frame lens is mounted onto the APS-C frame camera body, the crop factor is negated and you can get a full view filed though the lens. This solves the issue of edge cracking in photos caused by adapter without optical glasses and allows for sharper images. The image will also be much brighter due to an increased concentration of light, equal to one stop more aperture value for a typical lens for the same aperture value. This increase is more obvious when the lens aperture value is less than 2.<\/p>\n
This adapter has an additional feature of autofocus with accurate and quick focus for a steady performance. The adapter is equipped with electronic contact and built-in circuit board with chip, besides auto-focus and stability function, it also can transmit precise EXIF information to the camera body.<\/p>\n
