For BMPCC 4K camera with Full Frame Lenses + CINE Lock","description":"\u003cp\u003eThe BMPCC4K Speed Booster® ULTRA 0.71x and XL 0.64x are similar to the standard M43 Speed Booster adapters (MB_SPEF-m43-BT5 and MB_SPEF-m43-BT6) but the optics have been re-designed to optimize for the filter stack thickness of 2.4mm found in Blackmagic cameras rather than the 4mm of a standard Micro Four Thirds.\u003c\/p\u003e\n\n\n\n\u003cp\u003eIn addition to optimized optical design, the CINE version is equipped with an extremely robust cine-style positive locking mechanism to ensure that no play occurs during focusing. This is especially important when using EF lenses for cine work because even though they provide a very smooth focus movement.\u003c\/p\u003e\n\n\n\n\u003cp\u003eMetabones Canon EF to BMPCC4K Speed Booster\u003cem\u003e \u003c\/em\u003eadapters are designed exclusively for Blackmagic Design Pocket Cinema Camera 4K (BMPCC4K). \u003cem\u003eThey cannot be attached to any other M43 cameras such as JVC, Olympus or Panasonic cameras.\u003c\/em\u003e\u003c\/p\u003e\n\n\n\n\u003cp\u003eThe BMPCC4K Speed Booster XL 0.64x reduces the crop factor of the BMPCC 4K camera from 2.02x to 1.29x and produces the largest aperture optics currently available, with a maximum output aperture of f\/0.8.\u003c\/p\u003e\n\n\n\n\u003cp\u003eWhy Metabones?\u003c\/p\u003e\n\n\n\n\u003cp\u003eSince its inception, Metabones has been designing and manufacturing lens adapters recognized among professionals and enthusiasts as leaders in design and workmanship.\u003c\/p\u003e\n\n\n\n\u003cp\u003eContrary 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.\u003c\/p\u003e\n\n\n\n\u003cp\u003eMetabones uses matte-black treatment to keep internal reflection to a minimum in order to maintain the maximum optical quality possible with the lens.\u003cbr\u003e\n\nAll Metabones Adapters follow this tradition of uncompromising precision, robust build quality and outstanding finish.
