Fujifilm Photography News and Rumors

B&H Photo listed the Metabones Contax 645 Mount to G-mount and Metabones Canon FD to X-Mount Speed Booster ULTRA 0.71x. Both are special orders and the Canon FD adapter was announced a while ago, but the Contax 645 adapter is a pretty recent release. The specs are below:

Metabones Contax 645 Mount to G-mount

• Contax C645 Lens to Fujifilm G-mount camera
• Electronic control supported: Autofocus, Aperture control, and EXIF support,
• LED indicator shows communication status.
• PDAF camera support.
• IBIS of camera support.
• Aluminum alloy and brass construction with chromium plating.
• Satin surface finish.
• Detachable Arca-Type tripod foot compatible with Arca Swiss, Markins, and Photo Clam ball heads(clamp directly or attach to the quick-release plate by a 1/4″-20 screw).

Owners of legendary Carl Zeiss optics in Contax 645 Mount now have a trusted migration path to mirrorless cameras with Metabones® Contax 645 to Fujifilm GFX Smart Adapter and Metabones Contax 645 to Sony E-Mount Smart Adapter.

Get the ergonomic experience of the original Contax 645 camera by using the lens’ own aperture ring in aperture priority and manual exposure modes. Fully automatic exposure and shutter priority are also available. A customizable button on the E-Mount variant can be assigned to more than 50 different functions on many Sony cameras, including depth-of-field preview. A tripod foot compatible with Arca-Swiss-style quick release is included.

Metabones has a proven track record of firmware stability and timely firmware support. Firmware is user-upgradable via the Smart Adapters’ micro USB ports.

All Metabones Smart Adapters relay distance information from the lens to the camera body to enable 5-axis in-body image stabilization (IBIS). The Contax 645 Makro-Planar 4/120 lens does not report distance information and supports only 3-axis in-body image stabilization.

When Contax 645 was launched in 1999 it was the most technologically advanced medium format camera at the time, and the first interchangeable lens medium format system with autofocus motors built into the lenses. These legendary Carl Zeiss lenses are now leveraging the latest and greatest mirrorless camera features and poised to benefit from further technological advances in the future.

Metabones Canon FD to X-Mount Speed Booster ULTRA 0.71x

• Increase maximum aperture by 1 stop ;
• Increase MTF ;
• Makes lens 0.71x wider ;
• Aluminum Alloy and Brass Construction with Chromium Plating ;
• Satin Surface Finish ;
• Detachable Arca-Type tripod foot compatible with Arca Swiss, Markins, and Photo Clam ball heads(clamp directly or attach to quick release plate by a 1/4″-20 screw).

Speed Booster ULTRA
Sharper corners, less distortion, reduced vignetting 

New optical design:  advanced 5-element/4-group optical design incorporating ultra-high index tanatalum-based optical glass to achieve extraordinary optical performance with improved corner sharpness, distortion and reduced vignetting.

Like the revolutionary original Metabones Speed Booster announced in January 2013, the Speed Booster ULTRA has a magnification of 0.71x, and so it effectively reduces the crop factor of mirrorless cameras with DX-sized sensors, such as Sony E-mount and Fuji X-mount cameras, from 1.5x to 1.07x.  However, the new ULTRA design makes very effective use of exotic materials at the furthest limit of glassmaking technology, and as a result is well corrected for use with virtually all full-frame SLR lenses regardless of exit pupil distance. 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.
