Metabones Canon EF to MFT T CINE Speed Booster XL 0.64x SKU: MB_SPEF-m43-BT6 The Speed Booster XL 0.64x is similar to the Blackmagic 0.64x BMCC Speed Booster (DISCONTINUED), but has been completely re-designed to meet the following requirements: The working distance has increased by 1mm to permit use on the Panasonic GH4 and a number of other Micro Four Thirds cameras without touching the flexible outer cover of the camera’s shutter mechanism. The optics are optimized for a standard Micro Four Thirds filter stack thickness of 4mm rather than the 2.4mm found in Blackmagic cameras. The image circle diameter has been increased to 21.63mm so that the full 17.3mm x 13mm Four Thirds format is covered.  This has been achieved while maintaining unusually high image quality over the 17.4mm image circle used by the Panasonic GH4 in its Cinema 4k video mode. Although the Speed Booster XL 0.64x has extra clearance compared to the 0.64x BMCC Speed Booster, there are still a number of Micro Four Thirds cameras that are not supported due to mechanical clearance issues.  This is summarized in the table below, which is color-coded so that Green means the camera is supported and Red means the camera is not supported.  Note that many of the Red-coded cameras actually do function, but there is a minor interference with the protective shutter cover.  Although slight contact with the shutter cover appears to have no effect on the functioning or cosmetics of either the camera or the Speed Booster we cannot support these combinations due to possible risk of damage. Autofocus with an Optimum Balance of Accuracy, Speed, Consistency and Reliability New in Speed Booster XL for Canon EF Mount to Micro Four Thirds is autofocus support, 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.

Metabones Canon EF to MFT T Smart Adapter SKU: MB_EF-m43-BT2 Starting from firmware V1.7, autofocus is enabled on Panasonic camera bodies, subject to certain limitations. The Panasonic Micro Four Thirds camera bodies are capable of autofocusing fast (large maximum aperture) lenses accurately. Although first and foremost priority is accuracy, Metabones is 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). Some improperly-made M42 screw mount adapters may short the electronic contacts of the Metabones Smart Adapter and cause damage to the Smart Adapter and/or camera body. Focus confirmation "chips" such as Dandelion are incompatible. Many manual focus lenses (e.g. OM 28/2.8, OM 50/1.8, Leica R 15/3.5) have rear protrusions (spikes, levers, other appendages) which would damage the housing of Smart Adapter. They need to be modified before they can be safely used on Smart Adapter. Check and make sure there are no rear protrusions from the adapter/lens combination before using on Smart Adapter.

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.

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)

Optical/mechanical Felt material flocked inside the opening to reduce internal reflection.Fits both EF and EF-S lenses. (Vignetting at corners may occur with certain EF-S lenses because they are designed to cover a 1.6x crop image circle but Sony APS-C has a 1.5x crop factor.) Autofocus AF-C is supported on A9, A7RIII, A7III, A7RII, A7II, A6500 and A6300 only, and only in Green mode.Continuous video AF is functional in Advanced mode, but performance may be unsatisfactory.On Sony A9, only phase-detection autofocus is supported. Contrast-detection autofocus does not work. See firmware release notes for details.AF may not work if the maximum aperture of the lens plus any EF Extender or other teleconverter attached is smaller than f/8.The first two autofocus attempts are used to calibrate the lens and as a result may not lock successfully on the target. Half-press the shutter release button again and autofocus will lock successfully.Autofocus may have difficultly locking onto subjects which are very close to the nearest focusing distance of the lens.Sony E-mount 1.4x TC (model SEL14TC) will fit and work but AF performance may be unsatisfactory and there may be significant vignetting with some telephoto lenses.Autofocus accuracy depends heavily on the design and working condition of the lens. Lenses with hidden problems which may not be apparent on Canon DSLRs will lead to inaccurate and unreliable autofocus on Sony. Typical problems of this kind that we have seen include an unsmooth/erratic autofocus mechanism (e.g. getting stuck intermittently at a certain focusing distance), a faulty/worn-out distance encoder or other faulty/worn-out internal sensors. Other No support for lens corrections such as peripheral shading, CA and distortion.Use of Canon Compact-Servo Cinema lenses such as CN-E 18-80mm T4.4 for still photography is not supported. (Functional, but slower than lenses designed for still photography.)Some EF-mount lenses may make audible noises during iris changes and autofocus, which may be picked up by the built-in microphone of the camera during video recording. Use of an external microphone is advised. Some of the recently-introduced Canon-brand lenses are very quiet, however.Early Tamron VC lenses such as the AF 28-300/3.5-6.3 XR Di VC LD Aspherical [IF] Macro (model A20), AF 18-270/3.5-6.3 Di II VC LD Aspherical [IF] MACRO (model B003), SP AF 17-50mm F/2.8 XR Di II VC LD Aspherical [IF] (model B005) may not be able to freely switch between OIS and IBIS because they may not report IS activity status. Later Tamron VC lenses equipped with USD or PZD focus motors are fine.Some aftermarket battery grips may cause the aperture to change erroneously. This is a bug in the aftermarket battery grip but NOT arising from the Metabones Smart Adapter. Turn off the aftermarket battery grip or use a genuine Sony battery grip.

Metabones Canon EF Lens to Sony E Mount T CINE Speed Booster ULTRA 0.71x SKU: MB_SPEF-E-BT3 New optical design:  advanced 5-element/4-group optical design incorporating ultra-high index tantalum-based optical glass to achieve extraordinary optical performance with improved corner sharpness, distortion and reduced vignetting. Speed Booster ULTRA has a magnification of 0.71x, and so it effectively reduces the crop factor of mirrorless cameras with DX-sized sensors, such as Sony E-mount and Fuji X-mount cameras, from 1.5x to 1.07x.  However, the new ULTRA design makes very effective use of exotic materials at the furthest limit of glassmaking technology, and as a result is well corrected for use with virtually all fullframe SLR lenses regardless of exit pupil distance. Thus, the Metabones Speed Booster ULTRA 0.71x performs extremely well with professional-grade f/2.8 zoom lenses such as the 24-70mm f/2.8 and 70-200mm f/2.8 zooms by Canon and Nikon to produce 17-50mm f/2.0 and 50-142mm f/2.0 high-speed zooms, respectively.  Similarly, high-speed fixed focal length lenses such as a 50mm f/1.2 will be transformed into a 35.5mm f/0.9 lens with excellent contrast and resolution from the center all the way to the edges of the image Optical/Mechanical Increase maximum aperture by 1 stop.Increase MTF.Makes lens 0.71x wider.Advanced 5-element/4-group optical design incorporating ultra-high index tantalum-based optical glass by Caldwell Photographic in the USA (patent pending).A new positive-lock EF lens mount.

Metabones Hasselblad V to Fujifilm G CINE Speed Booster ULTRA 0.71x SKU: MB_SPHV-FG-BM1 The new Speed Booster Ultra 0.71x is an ideal match for 6x6 Hasselblad V lenses since they can now be fully utilized as they were originally designed when mounted to the Fuji GFX. Unlike 35mm format lenses used on the Fuji GFX via glassless adapters, Hasselblad V lenses adapted to the GFX via the Speed Booster Ultra are completely free of disturbing vignetting and other corner issues. In addition to increasing the field of view and lens speed, the new Speed Booster Ultra achieves superb performance by being carefully matched to the unique optical characteristics of the Hasselblad V lenses. All of the Hasselblad V lenses were analyzed for exit pupil size and location, and this was fully taken into account in the new Speed Booster Ultra for the Fuji GFX. This approach dictated the use of extremely large lens elements throughout in order to avoid vignetting and maintain high-quality imagery into the corners, but the results speak for themselves. Like all Metabones Speed Boosters, the Hasselblad-V to GFX Speed Booster Ultra is optimized to fully account for the camera’s filter stack located near the sensor surface. This is especially critical when using high-speed optics like the 110mm f/2, which becomes a high-performance 78mm f/1.4. In addition to superb optical performance, the Hasselblad-V to GFX Speed Booster Ultra 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 Hasselblad V lenses for cine work because even though they provide a very smooth focus movement, they tend to require more torque than lesser lenses. The new Ultra also includes a very sturdy 360-degree rotation collar and extra length Arca Swiss style tripod mounting plate. MB_SPHV-FG-BM1 Features Design for adapting Hasselblad V-mount Lens to Fuji GFX (G-mount) cameras.Makes lens 0.71x wider. Crop Factor for Fuji GFX format relative to 6x6 film format: 1.03x.Increase maximum aperture by 1 stop.Increase MTF.Patented 6-element/4-group optical design incorporating ultra-high index tantalum-based optical glass by Caldwell Photographic in the USA.Positive-lock V lens mount (patent granted).Lens Compatibility: Any Hasselblad V Mount lens.
