The adapter's optics help to maximise the connected lens's apparent angle of view while providing a one-stop increase for the camera over the lens's aperture range. A full-frame Canon EF-mount lens is designed to project an image that is larger than a Canon EF-M mount camera's APS-C sensor. Ordinarily, that sensor would only be able capture the centre portion of the projected image, creating an in-camera \"crop factor.\" Inside this adapter, five optical elements in four groups condenses the light from the full-frame lens and effectively reduces the crop factor. This also makes available to the sensor an additional one stop of light throughout the lens's aperture range.\u003c\/p\u003e\n\u003cp\u003eThe Metabones Canon EF to EOS M T Speed Booster ULTRA  0.71x - With Tripod Foot (MB_SPEF-EFM-BT1) is constructed from aluminium alloy for durability while minimising weight and its mounting rings are made with brass to further prevent wear-and-tear. An internal, matte black coating prevents the appearance of reflections within the adapter barrel, and to help reduce stress on the camera mount when placed on a tripod, the adapter includes a detachable Arca-type compatible tripod foot with 1\/4\"-20 threads.\u003c\/p\u003e\n\u003cp\u003eThe Metabones Canon EF to EOS M T Speed Booster ULTRA  0.71x - With Tripod Foot (MB_SPEF-EFM-BT1) supports electronic communication between an attached camera and lens. If the lens includes autofocus, image stabilisation, as well as camera-controlled aperture functions, this adapter is intended to allow use of those features. Also, if an attached lens is capable of generating EXIF metadata when used with a directly compatible camera, this adapter is designed to transfer that information, so it can be saved along with image files generated the combined Canon EF-mount lens and Canon EF-M mount camera.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eAllows a full-frame Canon EF-mount lens to be used on a Canon EF-M mount camera\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSupports electronic communication between camera and lens to enable autofocus, image stabilisation, on-camera aperture control, and EXIF metadata generation when possible\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e0.71x magnification maximises angle of view of combined camera and lens\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eProvides a 1-stop increase for the camera over the lens's aperture range\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eFive lens elements in four groups for optical clarity as well as color fidelity\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eInternal, black matte coating minimises the appearance of reflections within the adapter barrel\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAluminum alloy components for weight reduction\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eBrass mounting rings prevent wear-and-tear\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDetachable Arca-type tripod foot with 1\/4\"-20 threads can be used to reduces stress on a connected camera's mount\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eLocking mechanism for secure attachment of lens with push-button release\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eCanon EF Lens to Canon EF-M Body\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eFull-Frame Lens to EF-M Camera Body\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e0.71x APS-C Crop Factor Compensation\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1-Stop Increase in Lens Apertures\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSupports In-Camera Aperture Control\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTransfers Lens EXIF Metadata to Camera\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAnti-Reflective Matte Black Interior\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eBrass Mounting Rings\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRemovable, Arca-Type Tripod Foot\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1\/4\"-20 Tripod Foot Accessory Threads\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e What's in the Box\u003c\/h3\u003e\n\u003cul data-selenium=\"includesInTheBoxList\" class=\"list__cXkStmX9s\"\u003e\n\u003cli data-selenium=\"includesInTheBoxItem\" class=\"item_u6ujeLWy3W\"\u003e\n\u003cp\u003e\u003cspan\u003eMetabones T Speed Booster Ultra 0.71x Adapter for Canon Full-Frame EF-Mount Lens to Canon EF-M Mount Camera\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-selenium=\"includesInTheBoxItem\" class=\"item_u6ujeLWy3W\"\u003e\n\u003cp\u003e\u003cspan\u003eFront Cap\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-selenium=\"includesInTheBoxItem\" class=\"item_u6ujeLWy3W\"\u003e\n\u003cp\u003e\u003cspan\u003eRear Cap\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-selenium=\"includesInTheBoxItem\" class=\"item_u6ujeLWy3W\"\u003e\n\u003cp\u003e\u003cspan\u003eTripod Foot Key\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Metabones","offers":[{"title":"Default Title","offer_id":43239773995175,"sku":"GC47-MB-177","price":1180.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/4083\/0375\/products\/MB-177_3.jpg?v=1679475549","url":"https:\/\/www.georges.com.au\/products\/metabones-canon-ef-to-eos-m-t-speed-booster-ultra-0-71x-with-tripod-foot-mb_spef-efm-bt1","provider":"Georges Cameras","version":"1.0","type":"link"}
