<p>Metabones&amp;nbsp;MB_SPFD-E-BM2 (MB_SPFD_E_BM2,&amp;nbsp;MB/SPFD/E/BM2,&amp;nbsp;MB SPFD E BM2)&amp;nbsp;Canon FD to E-mount Speed Booster ULTRA 0.71x (Black Matt)
The Canon FD Lens to Sony E-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 Canon FD lens to be mounted to an APS-C format E-Mount camera and in doing so, increases the angle of view and increases the maximum aperture by approximately one f/stop.&amp;nbsp;
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 decreases. 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&#039; 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.&amp;nbsp;
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. This adapter has a detachable tripod foot that is compatible with Arca Swiss, Markins, and Photo Clam ball heads.
Although the lens will fit physically, automatic diaphragm (AE metering), or other auto functions are not retained using this speed booster. These speed boosters are only fully compatible with mirrorless cameras housing APS-C or smaller image sensors. They will physically fit the Sony full frame mirrorless cameras, but the camera must be set in Crop Mode to fully support the speed booster&#039;s functions.

Allows a full frame Canon FD lens to be mounted to an E-mount APS-C format camera and in doing so, increases the angle of view and increases the maximum aperture by one f/stop.
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.

<p>Metabones&amp;nbsp;MB_SPA-X-BM2 (MB_SPA_X_BM2,&amp;nbsp;MB/SPA/X/BM2,&amp;nbsp;MB SPA X BM2)&amp;nbsp;Sony Alpha to X-mount Speed Booster ULTRA 0.71x (Black Matt)
The Speed Booster Ultra 0.71x Adapter for Sony A-Mount Lens to Fujifilm X-Mount Camera from Metabones allows a full-frame Sony A-mount lens to be mounted onto a Fujifilm X-mount camera. While doing so, the adapter&#039;s optics help to maximize the connected lens&#039;s apparent angle of view while providing a 1-stop increase for the camera over the lens&#039;s aperture range.
If a lens intended for 35mm film or similarly sized full-frame camera sensors is connected to a camera with a Fuji X-mount APS-C-sized sensor, it would project an image larger than the Fuji X-mount APS-C 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 &quot;crop factor.&quot; The Speed Booster Ultra 0.71x Adapter for Sony A-Mount Lens to Fujifilm X-Mount Camera condenses the light from a lens designed for 35mm film or &quot;full frame&quot; camera sensors and projects it onto a Fuji X-mount APS-C sensor. This allows a Fuji X-mount APS-C 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&#039;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 3/8&quot; threads as well as compatibility with Arca-Swiss tripod heads.
The Speed Booster Ultra 0.71x Adapter for Sony A-Mount Lens to Fujifilm X-Mount Camera does not support electronic communication between an attached camera and lens. To help determine the amount of light that enters a Fujifilm X-mount camera when using this adapter and a Sony A-mount lens, an aperture dial is built into the Speed Booster Ultra 0.71x Adapter for Sony A-Mount Lens to Fujifilm X-Mount Camera.

Although the lens will fit physically, automatic diaphragm (AE metering), or other auto functions are not retained using this speed booster.&amp;nbsp; 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.

Allows a full frame ALPA lens to be mounted to an Fujifilm X-mount APS-C format camera and in doing so, increases the angle of view and increases the maximum aperture by one f/stop.
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.
Although the lens will fit physically, automatic diaphragm (AE metering), or other auto functions are not 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

The Leica R Lens to Blackmagic Cinema Camera Speed Booster from Metabones allows you to mount a Leica R lens on a Blackmagic Cinema Camera, while using custom optics to increase the angle of view and the maximum aperture of the lens.
The Speed Booster works by shrinking the image circle of your Leica R lens down to better fit the smaller sensor of the Blackmagic Cinema Camera. This has the effect of making the angle of view of the lens 0.64x wider or, in other terms, reducing the crop factor of the camera from 2.39x to 1.53x. This yields an angle of view similar to APS-C or Super 35 sized sensors.
When the Speed Booster concentrates the image circle from a lens, the brightness of the image is increased by 1 1/3 stops, with a maximum output aperture of f/0.9 when using a Leica R f/1.4 lens. In addition to lens speed and angle of view, the Speed Booster also increases the lens&#039; MTF, or how faithfully the lens transfers detail from the object to the camera sensor. These increases in MTF are seen in the corners as well as the center of the images. For added lens support, a removable Arca-type tripod foot is included.

Super telephotos such as the Telyt 560/5.6 may vignette at the corners.
