Metabones T Speed Booster ULTRA 0.71x Adapter- Kameraanschluss: Fujifilm X
- Lens adapter
- Focal length extension by 0.71x
- Increase of the maximum aperture by 1 f-stop
- advanced optical 5-element/4-group design made of ultra-high index tantalum-based optical glass
- suitable for Canon EF Lens on Fujifilm cameras with X bayonet
- Autofocus support with phase detection (PDAF)
- Adjustment of focal length and aperture in EXIF
- detachable AS tripod base
- Flocking against internal reflection
Like the revolutionary original Metabones Speed Booster® announced in January 2013, the Speed Booster ULTRA has a magnification of 0.71x, effectively reducing the crop factor of mirrorless cameras with DX-size (APS-C) sensors, such as Sony E-mount and Fuji X-mount cameras, from 1.5x to 1.07x. However, the new ULTRA design very effectively utilizes exotic materials at the extreme limits of glass manufacturing technology and is therefore well corrected for use with virtually all full frame SLR Lens regardless of exit pupil distance. For example, the Speed Booster ULTRA works exceptionally well with professional f/2.8 zoom lenses such as the 24-70mm f/2.8 and 70-200mm f/2.8 from Canon and Nikon to produce 17-50mm f/2.0 and 50-142mm f/2.0 high-speed zooms respectively. Similarly, fast fixed focal lengths such as a 50mm f/1.2 are converted into a 35.5mm f/0.9 Lens with excellent contrast and resolution from the center to the edges of the image.
