Metabones Canon EF to MFT T Speed Booster SUPER16 0.58x for Blackmagic

Metabones Canon EF to BMPCC4K T Speed Booster XL 0.64x SKU: MB_SPEF-m43-BT9 The BMPCC4K Speed Booster ULTRA 0.71x and XL BMPCC4K Speed Booster ULTRA 0.64x are similar to the standard M43 Speed Booster adapters (MB_SPEF-m43-BT3 and MB_SPEF-m43-BT4) 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. Metabones Canon EF to BMPCC4K Speed Booster adapters are designed exclusively for Blackmagic Design Pocket Cinema Camera 4K (BMPCC4K). They cannot be attached to any other M43 cameras such as JVC, Olympus or Panasonic cameras. The 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.

Metabones Canon EF to MFT Speed Booster XL 0.64x SKU: MB_SPEF-m43-BT3 A new Micro-4/3 mount Speed Booster adapter designed exclusively for the Panasonic GH4 and other selected Micro Four Thirds cameras with a magnification of 0.64x. The Metabones Speed Booster XL 0.64x uses an advanced 6-element optical design to achieve extraordinary optical performance at apertures up to an incredible f/0.80, a new record for Micro Four Thirds format.  The new Speed Booster XL 0.64x reduces the full-frame crop factor of the Panasonic GH4 from 2.0x to 1.28x, thus effectively transforming these cameras into APS-H format. When the GH4 is used in Cinema 4k video mode the horizontal full frame crop factor is reduced from 2.34x to 1.50x, thus effectively transforming the GH4 into a super-35 format 4k cine camera. In addition, the speed of any attached lens is increased by 11/3 stops, with a maximum output aperture of f/0.80 when an f/1.2 lens is used. For example, a 50mm f/1.2 becomes a 32mm f/0.80, which is the fastest aperture available for full size Micro Four Thirds formatSupports Panasonic GH4, GH3, G3, G5, G6, G10, GF3, GF5, GF6, GX1, Olympus E-PL7Blackmagic Cinema Camera with Micro Four Thirds mount, Blackmagic Pocket Cinema Camera Speed Booster XL 0.64x Specifications Magnification:  0.64xCrop Factor for Full Micro Four Thirds format:  1.28xCrop Factor with GH4 in Cinema 4k (4096 x 2160) Video Mode:  1.5xMaximum Output Aperture:  f/0.80 (with f/1.2 lens attached)Rectilinear Distortion:  < 0.8%Lens Elements/Groups:  6/4Length Reduction:  6.2 mmCamera Mount:  Micro Four ThirdsImage Format:  17.3 mm x 13.0 mm (full Micro Four Thirds format)

VILTROX EF-M2 II Viltrox EF-M2 mount adapter is designed to allow Canon EF-mount series lens to be used on M43 camera. EF-M2 II features electronic contacts to maintain autofocus, auto-exposure, image stabilization capabilities, transfer Exif data and enable aperture adjustment from the camera body. This Viltrox adapter features 0.71x-magnification focal reducer, which helps to offset much of the crop factor of Micro Four Thirds cameras as well as concentrates the light in order to increase the effective aperture by one stop. Features Plus 0.71 based on the original focal length (equivalent focal length=focal length x0.71), which help enlarge 1 level aperture.Build-in 4groups, 4pcs optical glasses, AF(autofocus) and adjustable aperture,etc.Gold-plated electronic contact, Auto-focus functionIt can realize AF,adjustable aperture from camera body to lens's apertureMore durable metal materialCompatible for all the EF-lens Specification Compatible lenses: Canon EF series lensesCompatible cameras: M43 series camerasFocus mode: Auto focusFocal Lenth Multiplier: 0.71xOptical glasses: 4 groups, 4 glassesTripod Socket: Cu1/4"× 1Diameter and Length: Φ67mm x 25mm.Weight: Approx. 85 g (excluding cap)Front cap: Camera coverRear cap: Lens Dust cap

Metabones Canon EF to MFT T T ULTRA 0.71x Speed Booster Adapter SKU: MB_SPEF-M43-BT4 The new Metabones Speed Booster ULTRA 0.71x Adapter m43 uses an advanced 5-element 4-group optical design incorporating ultra-high index tantalum-based optical glass.  However, the new design is specifically optimized for the Micro Four Thirds sensor and filter stack, and as a result achieves an astonishing level of performance that sets a new standard for focal reducers. Like the revolutionary original Metabones Speed Booster® announced in January 2013, the Speed Booster ULTRA m43 has a magnification of 0.71x, and so it effectively reduces the crop factor of mirrorless Micro Four Thirds mount cameras from 2.0x to 1.4x.  However, the new ULTRA design makes very effective use of exotic materials at the furthest limit of glassmaking technology, and as a result is almost perfectly corrected for use with all fullframe SLR lenses regardless of aperture.  The Speed Booster ULTRA m43 will also work extremely well with many DX and APS-C format lenses provided the image circle of the lens is large enough.  Optical performance of the new Speed Boosters is so good that the MTF of any lens attached to it will be improved.  Even the latest generation of ultra-high performance SLR lenses such as the Zeiss Otus series can be improved by adding a Speed Booster ULTRA m43. New in Metabones Speed Booster ULTRA for Canon EF Mount to Micro Four Thirds is autofocus on Panasonic camera bodies, subject to certain limitations (see table above for details). We are pleased to report that Panasonic Micro Four Thirds camera bodies are capable of autofocusing accurately even if the maximum aperture of the Speed Booster and the lens combined is in the sub-f/1.0 range. Although our first and foremost priority is accuracy, we are able to make great strides in autofocus speed as well, which is significantly faster than a DSLR Four Thirds lens on a Panasonic Micro Four Thirds camera (with adapter), or our E-mount offerings on Sony cameras prior to Alpha 7R II.
