Caldwell Photographic and Metabones have announced the Speed Booster Q666, also known as “The Devil’s Speed Booster”, exclusively for Pentax Q series cameras.
The unusual nickname apparently stems from the fact that the new adapter boasts a record-breaking f/0. 666 aperture and a 0. 5x magnification. Like all Metabones Speed Boosters, the Speed Booster Q666 is optimised to fully account for the camera’s filter stack located near the sensor surface. This is especially critical at the maximum aperture of f/0. 666. As a result, a huge range of optics, from vintage film lenses to the latest digital designs, will function flawlessly when adapted to any Pentax Q camera. Planned lens mounts for the Speed Booster Q666 include a Pentax-K version and a Nikon F/G version with what Metabones claim to be "the most advanced Nikon G aperture adjustment mechanism in the industry. " The Speed Booster Q666 is available from the Metabones website and its worldwide dealer network for $489.
