Pārveidojiet savu Pentax Q-mount kameru par daudz jaudīgāku un daudzpusīgāku sistēmu, uzstādot Nikon F objektīvus, izmantojot šo 0,5x ātruma pastiprinātāju no Metabones. Izmantojot piecus īpaši augsta indeksa tantala stikla elementus četrās grupās, lai palielinātu redzes leņķi 0,5 reizes, šis adapteris var pārveidot pielāgoto objektīvu iespējas, lai precīzāk atdarinātu to dabiskā formāta objektīvu veiktspēju.
Tas samazina adaptētā objektīva šķietamo kadrēšanas koeficientu un vienlaikus uzlabo asumu un palielina maksimālo apertūru par aptuveni 1 f/stūri. Turklāt šajā manuālajā modelī var uzstādīt Nikon G tipa objektīvus, un tam ir iebūvēts diafragmas gredzens ar 8 regulēšanas soļiem, kas ļauj mainīt objektīva diafragmu.
Lai pielāgošanas procesu padarītu vieglāku un drošāku, šajā adapterī objektīva stiprinājumam ir izmantota atsperu lapu konstrukcija. Turklāt tas ir izgatavots no misiņa ar hroma pārklājumu, kas nodrošina izturību. Turklāt adapterim ir melna matēta iekšpuse, lai novērstu atspīdumus, un tam ir noņemama ar Arca tipa statīvu saderīga statīva kājiņa, lai mazinātu slodzi uz kameras stiprinājumu.
“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 utilized with minimal pixel vignetting effects commonly seen in other cameras used with high-speed lenses.

Why Metabones®?
Since its inception, Metabones has been designing and manufacturing lens adapters recognized among professionals and enthusiasts as leaders in design and workmanship.
Contrary to the popular trend of other factories using an aluminum ring painted black on the camera-body-side, we instead take no short-cut but use precision-machined brass with chromium plating on both the camera-body and the lens sides of our adapters, in order to ensure smooth mounting, great appearance, and durability. The lens side of the adapter features a strong leaf-spring structure, strengthening the adapter-lens connection and ensuring tightness of the lens in order to reduce wear and prevent focus errors and optical alignment issues from appearing.
Metabones uses matte-black treatment to keep internal reflection to a minimum in order to maintain the maximum optical quality possible with the lens.
All Metabones Adapters follow this tradition of uncompromising precision, robust build quality and outstanding finish. Our new Smart AdapterTM series of products add industry-leading electronic interfacing technology from Canada, with true electronic control of the lens' aperture directly from the camera body.
Features
- Both camera-side and lens-side of the adapter are made of brass, precision-machined and plated with chromium.
- Satin surface finish - just like your OEM lens and camera mounts.
- Precise fit and solid connection - lens has no play, gap or wiggling when mounted on adapter and no adjustments are required to fit your lens.
- Designed to reach infinity focus while maintaining the correct registration distance required to maintain optical quality of CRC lenses or lenses with floating elements.
Our Smart AdapterTM series adapters have the following additional features
- True electronic integration of aperture diaphragm - let camera automatically choose aperture in P or S exposure modes, or dial in yourself on the camera body in A or M modes.
- EXIF data such as lens identification, focal length and aperture.
