This has the effect of making the angle of view of the lens 0.64x wider or, in other terms, reducing the crop factor of the camera from 2.39x to 1.53x. This yields an angle of view similar to APS-C or Super 35 sized sensors.\u003c\/p\u003e\n\u003cp\u003eWhen the Speed Booster concentrates the image circle from a lens, the brightness of the image is increased by 1 1\/3 stops, with a maximum output aperture of f\/0.9 when using a Leica R f\/1.4 lens. In addition to lens speed and angle of view, the Speed Booster also increases the lens' MTF, or how faithfully the lens transfers detail from the object to the camera sensor. These increases in MTF are seen in the corners as well as the center of the images. For added lens support, a removable Arca-type tripod foot is included.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSuper telephotos such as the Telyt 560\/5.6 may vignette at the corners.\u003c\/li\u003e\n\u003cli\u003eThe following lenses require modification in order to fit on the Speed Booster:\u003c\/li\u003e\n\u003cli\u003eSuper-Elmar-R 15mm\u003c\/li\u003e\n\u003cli\u003eElmarit R 28\/2.8\u003c\/li\u003e\n\u003cli\u003eElmarit R 35\/2.8\u003c\/li\u003e\n\u003cli\u003eSummicron R 50\/2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eMetabones Speed Booster adaptor- Leica R to BMCC Micro FourThirds (Black Matt) - With Tripod Foot (MB_SPLR-BMCC-BM1)\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFits Leica R Lens to BMCC MFT Mount\u003c\/li\u003e\n\u003cli\u003eReduces Crop Factor to 1.53x\u003c\/li\u003e\n\u003cli\u003eIncreases Maximum Aperture by 1 1\/3 Stop\u003c\/li\u003e\n\u003cli\u003eRemovable Arca-Type Tripod Mount\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Metabones","offers":[{"title":"Default Title","offer_id":43239776714919,"sku":"GC47-MB-082","price":1085.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/4083\/0375\/products\/MB-082.jpg?v=1679548996","url":"https:\/\/www.georges.com.au\/products\/metabones-speed-booster-adaptor-leica-r-to-bmcc-micro-fourthirds-black-matt-with-tripod-foot-mb_splr-bmcc-bm1","provider":"Georges Cameras","version":"1.0","type":"link"}
