Limitations
	Metabones PL T CINE Speed Booster^® adapters are designed exclusively for the Zeiss CP.2, CZ.2, and CP.3 lenses. Important Notes: Do not attempt to mount the lenses not under the Lens Comparability List to the adapter - physical damage may occur. Using the PL lens OTHER THAN the CP.2/ CP.3 lens, the lens's rear element CANNOT protrude from the flange more than 14.5mm. (note.1)

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 full-frame 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)

New professional Mount-Rod Support Kit is also available (not included), which is compatible with all Metabones adapters with tripod foot.

Why Metabones®?

Since its inception, Metabones has been designing and manufacturing lens adapters recognized among professionals and enthusiasts as leaders in design and workmanship.

Contrary 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.

Metabones uses matte-black treatment to keep internal reflection to a minimum in order to maintain the maximum optical quality possible with the lens.

All Metabones Adapters follow this tradition of uncompromising precision, robust build quality and outstanding finish. Our new Smart Adapter^TM series of products add industry-leading electronic interfacing technology from Canada, with true electronic control of the lens' aperture directly from the camera body.

Features

Both camera-side and lens-side of the adapter are made of brass, precision-machined and plated with chromium.
Satin surface finish - just like your OEM lens and camera mounts.
Precise fit and solid connection - lens has no play, gap or wiggling when mounted on adapter and no adjustments are required to fit your lens.
Designed to reach infinity focus while maintaining the correct registration distance required to maintain optical quality of CRC lenses or lenses with floating elements.

Our Smart Adapter^TM series adapters have the following additional features

True electronic integration of aperture diaphragm - let camera automatically choose aperture in P or S exposure modes, or dial in yourself on the camera body in A or M modes.
EXIF data such as lens identification, focal length and aperture.
