Canon EF lens adapter to Sony E camera mount, advanced 5-element, 4-group optical design incorporating ultra-high index tantalum-based optical glass for optical performance with improved corner sharpness, distortion and reduced vignetting.


It has a magnification of 0.71x, effectively reducing the cropping factor of non-mirror cameras with DX-size sensors such as Sony E-mount and Fuji X-mount cameras from 1.5x to 1.07x.  It is well corrected for use with virtually all full frame SLR lenses, regardless of exit pupil distance. Thus, it works very well with professional-quality f/2.8 zoom lenses, such as Canon's and Nikon's 24-70 mm f/2.8 and 70-200 mm f/2.8 zooms, to produce high-speed zooms of 17-50 mm f/2.0 and 50-142 mm f/2.0, respectively.  Similarly, high-speed fixed focal length lenses, such as a 50mm f/1.2 lens, will be transformed into a 35.5mm f/0.9 lens with excellent contrast and resolution from the center to the edges of the image.


Robust construction and professional finish. Both the camera side and the lens side of the adapter are made of precisely machined, chrome-plated brass. Precise fit and solid connection with no slack, holes or jolts in the lens when mounted on the adapter and no adjustments are required to adapt it to your lens. Designed to achieve infinite focus while maintaining the correct registration distance needed to maintain the optical quality of CRC lenses or floating element lenses.

  • Dedicated switch controls in-body image stabilization (IBIS) on Sony cameras equipped with SteadyShot INSIDE
  • Compatible with Sony FS7 Mark II camera
  • Cinema EOS lens (CN-E) support, including power zoom, AF and auto iris
  • Rubber gasket protects E-mount connection from dust and moisture
  • Detachable tripod foot, compatible with Arca Swiss, Markins and Photo Clam ball heads
