Miete: Metabones Adapter von Canon EF zu M43 Speedbooster ULTRA 0.71x

Features and Benefits		Limitations
Optical Increase maximum aperture by 1 stop Increase MTF of any lens attached Makes lens 0.71x wider Patented 5-element/4-group optical design incorporating ultra-high index tantalum-based optical glass by Caldwell Photographic in the USA Supports 16:9 video with DX lenses. Electronic Autofocus Can be powered either by camera body or by third-party external 5V power source (not included) Iris/aperture controlled by the camera body Smooth iris support with the latest Canon (2009+), Tamron (SP series 2013+) and Sigma (2016+) lenses Image stabilization (IS) lens support Support for cameras with in-body image stabilization (IBIS), including Panasonic GX7, GX8, GX80/85 and Olympus cameras Electronic manual focusing (e.g. EF 85/1.2L II and discontinued EF 50/1.0L) EXIF (focal length, aperture, zoom range) Distance and zoom display on camcorders (requires lenses supporting distance information) Cinema EOS lens support (CN-E 18-80mm T4.4 L), including AF (requires external 5V power via micro USB port), auto iris and servo zoom Other Detachable tripod foot compatible with Arca Swiss, Markins and Photo Clam ball heads. The opening is flocked with felt material to reduce internal reflection. Compatible with all MFT mount cameras, including GH4, OM-D, Blackmagic Cinema Camera, Blackmagic Pocket Cinema Camera and JVC GY-LS300.		EF-S lenses require modification to fit or may remain incompatible even after modification (but third party DX lenses can be used without modification) Some EF-S and DX lenses may not have enough coverage of the entire image circle for stills after widening by 0.71x (but video will have enough coverage). No video AF for Olympus AF may not work if the maximum aperture of the lens plus any EF Extender or other teleconverter attached is smaller than f/8 before boost or smaller than f/5.6 after boost. AFC (continuous AF) and AFF (flexible AF) modes are not supported, except on Olympus OM-D E-M1. Panasonic video AF may hunt more than a native lens or have unsatisfactory performance. Some Tamron lenses may have unsatisfactory AF accuracy. No support for Focus Stacking and Focus Bracketing on Olympus. On Olympus, other than E-M1, you may move the single AF point among any of the 81, but you may not multi-point AF. There is no restriction on E-M1 and Panasonic. Very early Olympus models (e.g. E-PL1) have no autofocus support. EF-mount lenses are not silent but may make audible click noises during autofocus operation and iris changes which may be picked up by the built-in microphone of the camera. An external microphone is recommended for video. Use of Canon Cinema lenses such as CN-E 18-80mm T4.4L IS KAS S for still photography is not supported. Iris changes are in 1/8 stop steps which may be noticeable in video recordings. Programmed exposure mode and shutter priority exposure mode should not be used for video. This limitation does not apply to Cinema EOS lenses which permit fine resolution iris control, such as CN-E 18-80mm T4.4 L IS KAS S. No support for in-camera correction such as peripheral shading, CA and distortion Designed to cover a 24mm image circle, JVC GY-LS300 needs to have VSM configured to 86% (4k) when using a true Super 35 lens such as Canon CN-E 18-80mm T4.4L IS KAS S. Higher VSM settings is possible with full-frame lenses, but will be operating outside of the design parameters of the ULTRA optical formula. Many APS-C/DX lenses do not have adequate coverage at 86% (4k) and on JVC with ULTRA the use of full-frame or true Super 35 lenses is advised.

Description

Always Enhance and Never Degrade the Performance of the Attached Master Lens

Like the ULTRA series for Sony E-mount, the new Speed Booster ULTRA 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. (More information can be found in the press release here and whitepaper here)

Autofocus with an Optimum Balance of Accuracy, Speed, Consistency and Reliability

New in Speed Booster ULTRA 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.

Manual Focus Lens Compatibility

Some improperly-made M42 screw mount adapters may short the electronic contacts of the Speed Booster and cause damage to the Speed Booster 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 optics and/or housing of Speed Booster.They need to be modified before they can be safely used on Speed Booster. Check and make sure there are no rear protrusions from the adapter/lens combination before using on Speed Booster. Scratches and damages caused by rear protrusions on Speed Booster are not covered by warranty.
