This speed booster not only adapts the mount but also enhances the optical performance of the lens: it increases the maximum aperture by one stop (up to f\/0.9 in the best case), increases MTF (sharpness and contrast), and widens the angle of view by a factor of 0.71x, making the lens more wide-angle. All this is thanks to a patented optical design of 6 elements in 4 groups developed by Caldwell Photographic in the USA.\u003c\/p\u003e\u003cp\u003eThis second-hand accessory has been inspected and comes with the Camera Market warranty (6, 12, or 24 months), giving you peace of mind in your purchase. It is ideal for videographers looking to maximize brightness and image quality on their BMPCC4K without giving up the versatility of Canon EF lenses. Note that, being a product specific to the BMPCC4K, it is not compatible with other M43 cameras in a standard way. For detailed technical specifications, refer to the manufacturer's datasheet.\u003c\/p\u003e\u003cul\u003e\u003cli\u003eIncreases maximum aperture by 1 stop (up to f\/0.9)\u003c\/li\u003e\u003cli\u003eIncreases MTF (sharpness and contrast)\u003c\/li\u003e\u003cli\u003eMakes the lens 0.71x more wide-angle\u003c\/li\u003e\u003cli\u003ePatented optical design of 6 elements\/4 groups by Caldwell Photographic\u003c\/li\u003e\u003cli\u003eSpecific for Blackmagic Design BMPCC4K (M43 mount)\u003c\/li\u003e\u003cli\u003eIncludes Camera Market warranty (6\/12\/24 months) and technical inspection\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eIs it compatible with any Micro Four Thirds camera?\u003c\/h3\u003e\u003cp\u003eNo, this speed booster is specifically designed for the Blackmagic Design Pocket Cinema Camera 4K (BMPCC4K). Although the mount is M43, the optical design and fit are optimized for that camera, so its use on other M43 cameras is not recommended.\u003c\/p\u003e\u003ch3\u003eWhat advantages does the 0.71x factor provide?\u003c\/h3\u003e\u003cp\u003eThe 0.71x factor makes the lens more wide-angle, meaning it reduces the effective focal length. For example, a 50mm lens would behave like a 35.5mm. Additionally, by concentrating light, it increases the effective aperture by one stop, improving performance in low-light conditions.\u003c\/p\u003e\u003ch3\u003eDoes it affect image quality?\u003c\/h3\u003e\u003cp\u003eYes, positively. The patented optical design by Caldwell Photographic increases MTF (modulation transfer), which translates to greater sharpness and contrast in the image. It is a notable improvement compared to a simple adapter without optical elements.\u003c\/p\u003e\u003ch3\u003eWhat does the Camera Market warranty include?\u003c\/h3\u003e\u003cp\u003eThis second-hand product has been inspected and is covered by the Camera Market warranty, which you can choose between 6, 12, or 24 months. This protects you against possible malfunctions, offering you a safe purchase.\u003c\/p\u003e","brand":"Metabones","offers":[{"title":"Excelente","offer_id":58660852433228,"sku":"MPBGAP-metabones-canon-ef-to-bmpcc4k-t-","price":937.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0532\/6929\/9391\/files\/metabones-canon-ef-to-bmpcc4k-t-speed-booster-ultra-071x-1.jpg?v=1788360645","url":"https:\/\/cameramarket.us\/products\/metabones-canon-ef-to-bmpcc4k-t-speed-booster-ultra-0-71x-1","provider":"Camera Market","version":"1.0","type":"link"}
