Metabones Pentax K to Q-mount Speed Booster Devil Q666 0.50x (MB_SPPK-Q-BM1)

The Metabones Pentax K to Qmount Speed Booster Devil Q666 0.50x exclusively for Pentax Q series cameras. With its 0.5x magnification and world-record f/0.666 maximum speed it is crazy wicked fast. So make a deal with the devil today and turn your Pentax Q with its back-illuminated sensor into a monster low-light machine unlike anything ever seen in photography. Attach an f/1.2 lens and stop down a little to see how Stanley Kubrick made do with f/0.7 for filming those famous candle-lit scenes in “Barry Lyndon”. Or open up all the way to f/0.666 and probe the darkness in a way that no photographer has ever been able to do until now.
