Description

This Canon EF to Micro Four Thirds T CINE Speed Booster ULTRA 0.71x is designed specifically to mount a full-frame Canon EF lens to a Micro Four Thirds camera – accommodating a Micro Four Thirds sensor and filter stack. It offers near-perfect clarity through any full-frame SLR lens. This adapter can also be fully utilized by most DX and APS-C lenses with the correct size image circle – supporting 16:9 video with DX lenses. Additionally, its magnification of 0.71x compensates for the 2.0x crop factor of mirrorless Micro Four Thirds cameras, converting it to 1.4x.

This Speed Booster adapter opens up aperture by 1-stop for an overall, larger intake of light. Meaning a Micro Four Thirds camera can capture a larger image with the attachment of a full-frame lens. These images will hold sharp, crystal clear clarity as light is channelled perfectly through the five optical elements divided into four groups. The lens construction, which consists of ultra-high index tantalum-based optical glass, will improve the MTF of any attached lens.

This adapter features precision-machined brass connection points and chromium plating for long-lasting durability. Its positive-lock lens mount will secure to your lens tightly, reducing the potential for wear while eliminating focus errors and optical alignment issues. Thanks to its detachable foot, this T CINE Speed Booster is capable of mounting to an Arca-Swiss, Photo Clam or Markins tripod head.

This adapter connects to lenses electronically, for autofocus, aperture, image stabilization, distance display and zoom display support. Communicated EXIF data such as the lens identification, focal length and aperture of each attached lens is stored for quick collaboration the next time it’s attached.

Discover the advantages of using a full frame lens on a Micro Four Thirds camera and save yourself a lot of money by ordering this Metabones Canon EF to Micro Four Thirds T CINE Speed Booster ULTRA  0.71x adapter.

JVC GY-LS300 needs to have VSM configured to 86% (4k) when using a true Super 35 lens (e.g. Canon CN-E 18-80mm T4.4L IS KAS S)

 

Higher VSM settings is possible with full-frame lenses, but will be operating outside of the design parameters of the ULTRA optical formula.

 

Many APS-C/DX lenses do not have adequate coverage at 86% (4k) and on JVC with ULTRA the use of full-frame or true Super 35 lenses is advised.

Unsupported In-camera correction (e.g. peripheral shading, CA and distortion)
