“The Devil’s Speed Booster”, 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.
With an advanced 6-element optical design, the Q666 packs lots of optical horsepower in a small package. Sharpness is excellent even at f/0.666, and is downright superb if you stop down to f/1.0. Distortion is very low, with a maximum value of, naturally, 0.666%.
And thanks to the back-illuminated sensor used in Pentax Q cameras, the full f/0.666 maximum aperture can be utilised with minimal pixel vignetting effects commonly seen in other cameras used with high-speed lenses.
