Mitakon Zhongyi Lens Turbo Adapter V2 for Full-Frame Canon EF Mount Lens to Fujifilm X Mount APS-C Camera

The Mitakon Zhongyi Lens Turbo Adapter V2 for Full-Frame Canon EF Mount Lens to Fujifilm X Mount APS-C Camera from Mitakon Zhongyi allows a full-frame Canon EF mount lens to be mounted onto a Fujifilm X mount camera. While doing so, the adapter approximates the lens’s angle of view as if it were placed directly on a camera with a full-frame sensor while providing a 1-stop increase over the lens’s aperture range.

If a lens intended for 35mm film or similarly-sized “full-frame” camera sensors is connected to a camera with an APS-C sized sensor, it would project an image larger than the smaller sensor was built to accept. Able to capture only the center portion of the projected image, the effective angle of view of the lens would be narrowed, creating an in-camera “crop factor”. The Lens Turbo Adapter V2 for full-frame Canon EF Mount Lens to Fujifilm X Mount APS-C Camera condenses the light from a lens designed for 35mm film or “full-frame” camera sensors and projects it onto the APS-C sensor. This allows the APS-C sensor to utilize more of the light gathered by the lens, which effectively eliminates the crop factor while making available to the sensor an additional 1 stop of light for each of the lens’s f/stop settings.

This adapter is constructed from aluminum and plastic for durability while minimizing weight and its mounting rings are made of stainless steel to further prevent wear-and-tear. Inside are four lens elements, one of which is an extra-low dispersion element that helps to reduce chromatic aberrations.

When using the Lens Turbo Adapter V2 for full-frame Canon EF Mount Lens to Fujifilm X Mount APS-C Camera, a lens placed on it is kept securely attached via a push-button, side-locking knob. This adapter does not support electronic communication between an attached camera and lens. When removed from a compatible Canon camera, the aperture diaphragm on a Canon EF lens is designed to open to its widest setting. A Canon EF lens may be effectively used with its aperture diaphragm fully open along with this adapter and a Fujifilm X mount APS-C camera. Otherwise, an aperture value on a Canon EF lens may be set by first placing the lens on a Canon EOS camera and then pressing the camera’s depth of field preview button while removing the lens prior to placing it on the adapter.

This adapter may not fit all Canon EF mount lenses due to the degree with which rear optics may extend past the lens mount. Lenses with rear optics that extend more than 3mm past the lens mount are not recommended for use with the Lens Turbo Adapter V2 for full-frame Canon EF Mount Lens to Fujifilm X Mount APS-C Camera, and Blackmagic cinema cameras are incompatible as well.
