The Leica R Lens to FUJIFILM X-Mount Camera Speed Booster ULTRA from Metabones improves upon the original Metabones Speed Booster with a 5 element/4 group optical design that incorporates ultra-high refractive index tantalum-based glass for improved sharpness and reduced distortion and vignetting. The Speed Booster ULTRA allows a full frame Leica R lens to be mounted to an APS-C format X-Mount camera and in doing so, increases the angle of view and increases the maximum aperture by approximately one f/stop.

Metabones ULTRA Overview

The Leica R Lens to FUJIFILM X-Mount Camera Speed Booster ULTRA from Metabones improves upon the original Metabones Speed Booster with a 5 element/4 group optical design that incorporates ultra-high refractive index tantalum-based glass for improved sharpness and reduced distortion and vignetting. The Speed Booster ULTRA allows a full frame Leica R lens to be mounted to an APS-C format X-Mount camera and in doing so, increases the angle of view and increases the maximum aperture by approximately one f/stop. 

When a lens intended for full frame sensors or 35mm film is mounted to a camera with an APS-C sized sensor, it transmits a larger area of light than the smaller sensor was built to accept and therefore the effective angle of view of the lens increases. The Speed Booster condenses light from the lens and projects it onto the APS-C sensor allowing the sensor to utilize all of the lens' light and effectively reduces the crop factor of and APS-C E-Mount camera from 1.5x to 1.07x, producing a full-frame angle of view with an APS-C sensor. A corresponding increase in the maximum aperture of one f/stop makes the lens more effective in low-light situations and able to create a shallow depth of field. 

Although the lens will fit physically, automatic diaphragm (AE metering), or other auto functions are not retained using this speed booster.  Metabones Speed Boosters are quality made, using precision-machined brass with chromium plating on both the camera body and the lens side of the booster in order to ensure smooth mounting, quality aesthetic, and durability. A matte black interior reduces internal reflections and a black satin finish external surface matches with most camera bodies and lenses. This adapter has a tripod foot that is compatible with Arca Swiss, Markins, and Photo Clam ball heads, and can be removed if needed with an included hex key.

The Speed Booster ULTRA design incorporates ultra-high index tantalum-based optical glass for enhanced optical performance with improved corner sharpness and reduced distortion and vignetting. This glass technology and optical design perform extremely well with professional-grade f/2.8 zoom lenses and high-speed fixed focal length lenses such as a 50mm f/1.2 which will perform as a 35.5mm f/0.9 lens with high contrast and resolution from the center to the edges of the image.
Precise fit and solid connection - lens has no play, gap or wiggling when mounted on speed booster and no adjustments are required to fit your lens. Both the camera-side and the lens-side of the speed booster are made of brass which is precision-machined and chrome-plated.
The Speed Booster uses matte-black treatment to keep internal reflection to a minimum in order to maintain the maximum optical quality possible with the lens. The exterior features a black satin surface finish.
Designed to reach infinity focus while maintaining the correct registration distance required to maintain optical quality of CRC lenses or lenses with floating elements.
The speed booster features a detachable tripod foot which is compatible with Arca Swiss, Markins, Photo Clam ball heads. The booster may attach to a quick release plate or tripod using a 1/4"-20 screw.
Although the lens will fit physically, automatic diaphragm (AE metering), or other auto functions will not be retained using this speed booster.
Two hex keys included with the product, one to detach the tripod foot and another to tighten a mounting screw

question

When it says that certain Leica R lenses need to be modified to be used on this, what does that mean?
Asked by: Anonymous
There is a small metal lip that needs to be removed (with a metal saw/file) on the back of some Leica lenses (listed on the Metabones web site), otherwise it will hit the SpeedBooster's glass element. There is a risk of damaging the lens when removing this lip, so I asked a repair shop to do it for me. I don't think the lip has a mechanical function, but it prevents the back element of the lens to be scratched if you lay the lens on a table. So you will have to be extra careful how you handle the lens after you remove the lip.
