The T Speed Booster Ultra 0.71x Adapter for Canon Full-Frame EF-Mount Lens to Micro Four Thirds-Mount Camera from Metabones allows a full-frame Canon EF-mount lens to be mounted onto a Micro Four Thirds-mount camera. While doing so, the adapter's optics help to maximize the connected lens's apparent angle of view while providing a 1-stop increase for the camera 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 a Micro Four Thirds-sized sensor, it would project an image larger than the Micro Four Thirds 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 T Speed Booster Ultra 0.71x Adapter for Canon Full-Frame EF-Mount Lens to Micro Four Thirds-Mount Camera condenses the light from a lens designed for 35mm film or "full frame" camera sensors and projects it onto a Micro Four Thirds sensor. This allows a Micro Four Thirds sensor to utilize more of the light gathered by a connected lens, which effectively reduces 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 alloy for durability while minimizing weight and its mounting rings are made with brass to further prevent wear-and-tear. Inside are five lens elements in four groups that are designed to provide optical clarity as well as color fidelity, and a detachable tripod foot is included that features 1/4"-20 threads as well as compatibility with Arca-Swiss tripod heads.

The T Speed Booster Ultra 0.71x Adapter for Canon Full-Frame EF-Mount Lens to Micro Four Thirds-Mount Camera supports electronic communication between an attached camera and lens. If the lens includes autofocus, image stabilization, as well as camera-controlled aperture functions, this adapter is intended to allow those features to be used. Also, if an attached lens is capable of generating EXIF metadata when used with a directly compatible camera, the T Speed Booster Ultra 0.71x Adapter for Canon Full-Frame EF-Mount Lens to Micro Four Thirds-Mount Camera is designed to allow that information to be saved along with image files generated with a combination of the lens, a compatible Micro Four Thirds-mount camera, and the adapter.

  • Allows a full-frame Canon EF-mount lens to be used with a Micro Four Thirds-mount camera
  • Maximizes apparent angle of view of combined camera and lens
  • Provides a 1-stop increase for the camera over the lens's aperture range
  • Integrated jog dial for incremental aperture adjustment and push-button access to lens's widest aperture setting when used with a compatible Panasonic camera
  • Five lens elements in four groups for optical clarity as well as color fidelity
  • Supports electronic communication between camera and lens to enable autofocus, image stabilization, on-camera aperture control, and EXIF metadata generation when possible
  • Internal coating minimizes reflections within the adapter barrel
  • Detachable, Arca-Swiss compatible tripod foot with 3/8" threads
  • Aluminum alloy components for weight reduction
  • Brass mounting rings prevent wear-and-tear
  • Locking mechanism for secure attachment of lens with push-button release

Closing it when you have a ring.
Color: Black, Color: Black
Its a nice box but the problem i have with it is the middle piece. It does not give enough room if you have a ring that sits high like a cocktail ring. And same if you have a pendant necklace in the necklace area. You have ro really force it closed and i worry that it will put pressure on the items. It would work better without that middle piece for earrings or maybe if it were half the size. Closes fine when its empty but the minute you put a ring in the ring spot that has any kind of height you have to squeeze it shut. Its a good little box that you can put in a safe. Thats why i use it. Just to put my good jewelry in it and then secure it properly in a small house safe. Also ive already had the backs of a few earring pop off when I've opened the earring flap because it all rubs together. .
