Metabones MB_NFG-FG-BM1 Nikon G Lens to Fuji G Mount Adapter

Metabones MB_NFG-FG-BM1 (MB-NFG-FG-BM1, MB/NFG-FG-BM1, MB/NFG/FG/BM1, MBNFGFGBM1) Nikon G Lens to Fuji G Mount Adapter The Metabones Lens Adapter for Nikon F-Mount, G-Type Lens to FUJIFILM G-Mount GFX Camera does not support electronic communication between an attached camera and lens. To help determine the amount of light that enters a FUJIFILM G-mount GFX camera and a Nikon F-mount, G-type lens, an eight-stop aperture dial is built into this lens adapter. The aperture dial is designed to provide aperture control with full-stop increments for Nikon G-type lenses that do not have an aperture ring. Nikon AI or many post-Nikon AI lenses can have their aperture settings widened or narrowed using their built-in aperture control rings if preferred. When an image is taken with this Metabones Lens Adapter for Nikon F-Mount, G-Type Lens to FUJIFILM G-Mount GFX Camera, a matte black internal coating minimizes the potential for reflections inside the adapter barrel, which could otherwise result in unwanted glare within the image. To help prevent stress on the camera mount if the supported camera and lens combination is to be placed on a tripod, this lens adapter includes a detachable tripod foot that features 1/4"-20 threads as well as compatibility with Arca-type tripod heads. If a Nikon F-mount, G-type lens intended for 35mm film or similarly-sized full-frame camera sensors, as well as a Nikon F-mount, G-type lens for APS-C sized sensors is connected to a FUJIFILM G-mount GFX camera, it can project an image smaller than the camera's sensor was built to accept.

Metabones MB_SPOM-E-BM3 Olympus OM to E-Mount Speed Booster ULTRA 0.71x - Black Matte

Metabones MB_SPOM-E-BM3 (MB-SPOM-E-BM3, MB/SPOM-E-BM3, MB/SPOM/E/BM3, MBSPOMEBM3) Olympus OM to E-Mount Speed Booster ULTRA 0.71x - Black Matte The Olympus OM Lens to Sony E-Mount Camera Speed Booster ULTRA (Version 3) 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 Olympus OM 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. 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' light and effectively reducing 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. 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's functions. Allows a full frame Olympus OM 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 the 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, 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.

Thus, the Speed Booster ULTRA performs extremely well with professional-grade f/2.8 zoom lenses such as the 24-70mm f/2.8 and 70-200mm f/2.8 zooms by Canon and Nikon to produce 17-50mm f/2.0 and 50-142mm f/2.0 high-speed zooms, respectively.  Similarly, high-speed fixed focal length lenses such as a 50mm f/1.2 will be transformed into a 35.5mm f/0.9 lens with excellent contrast and resolution from the center all the way to the edges of the image.

Metabones MB_SPMD-E-BM2 (MB_SPMD_E_BM2, MB/SPMD/E/BM2, MB SPMD E BM2) Minolta MD to E-mount Speed Booster ULTRA  0.71x (Black Matt) The Metabones Minolta MD Lens to Sony E-Mount Camera ULTRA Speed Booster 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 Minolta MD 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. 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. 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's functions.
