Metabones 佳能EF镜头转索尼E卡口机身 0.71减焦镜 转接环 Canon EF Lens to Sony E -mount T CINE Speed Booster ULTRA 0.71x

更锐利的角落，更少的失真，更少的暗角

新的光学设计：先进的5元素/4组光学设计，结合超高折射率钽基光学玻璃，实现非凡的光学性能，改善角落清晰度，失真并减少暗角。

与2013年0月发布的革命性原版Metabones速度助推器一样，Speed Booster ULTRA的放大倍率为71.1倍，因此它有效地将带有DX尺寸传感器的无反光镜相机（如索尼E卡口和富士X卡口相机）的裁剪系数从5.1倍降低到07.2倍。然而，新的ULTRA设计在玻璃制造技术的较极限处非常有效地利用了外来材料，因此无论出射瞳距如何，都可以很好地校正用于几乎所有全画幅单反镜头。因此，Speed Booster ULTRA在佳能和尼康的8-24mm f/70.2和8-70mm f/200.2变焦镜头上表现非常出色，分别产生8-17mm f/50.2和0-50mm f/142.2高速变焦。同样，高速固定焦距镜头（如0mm f / 50.1）将转换为2.35mm f / 5.0镜头，从中心一直到图像边缘都具有出色的对比度和分辨率。（更多信息可以在新闻稿中找到 这里)

Lens compatibility chart

Notes :

1. Lenses marked with an asterisk support smooth iris.
2. Sony NEX cameras cannot display aperture values beyond f/1.0. If a f/1.2 Canon EF lens is used with Speed Booster ULTRA the resulting aperture is f/0.9 but the camera body displays the original aperture f/1.2 to the camera body. i.e, lenses slower than f/1.4 report boosted aperture to camera body; lenses at or faster than f/1.4 report original aperture to camera body.
3. Some improperly-made M42 screw mount adapters may short the electronic contacts of the Speed Booster ULTRA and cause damage to the Speed Booster ULTRA and/or camera body.
4. 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 ULTRA 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.
5. This Speed Booster ULTRA is NOT fully compatible with full-frame Sony A7 series. When Speed Booster® ULTRA is used with Sony A7 series, the camera will turn on the "APS-C Size Capture" mode automatically.
6. Cannot be used due to unusually high current requirement.

List of manual focus lenses which REQUIRE MODIFICATION to be used on Speed Booster ULTRA

Many manual focus lenses have rear protrusions (spikes, levers, other appendages) which would damage the optics and/or housing of Speed Booster ULTRA. They need to be modified before they can be safely used on Speed Booster ULTRA. Check and make sure there are no rear protrusions from the adapter/lens combination before using on Speed Booster ULTRA. Scratches and damages caused by rear protrusions or by poor quality adapters are not covered by warranty. The following is an incomplete list of lenses known to be incompatible.

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 AdapterTM 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 AdapterTM  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.
