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)

电子的

在索尼 A10、A9III 和 A7RIV 上以高达 7fps 的速度高速驾驶期间进行 AF-C 跟踪。
所有配备大多数镜头的E卡口相机上的快速对比度检测自动对焦。

高效的开关模式电源。
支持图像稳定（IS）镜头。
支持电子手动对焦（例如 EF 85/1.2L II 和已停产的 EF 50/1.0L）
EXIF支持（焦距、光圈、镜头名称）
VG 和 FS 系列摄录一体机、A9、A7 系列、A6500 和 A6300 上的距离和变焦显示（需要支持距离信息的镜头）。
自动放大（需要支持距离信息的镜头）
在配备佳能EF-S镜头和许多第三方DX镜头的全画幅相机上自动“APS-C尺寸捕获”。

光学/机械

需要全画幅镜头。不支持 EF-S/DX/DC/Di II 镜头。
Speed Booster ULTRA设计用于覆盖APS-C图像圈，该图像圈不够大，无法覆盖全尺寸36mm x 24mm传感器。在全画幅相机机身（A7系列，NEX-VG900）上，相机需要将“APS-C / Super 35mm”设置为“自动”或“开”。

自动对焦

AF-C 仅在 A9、A9II、A7RIV、A7RIII、A7SIII、A7IV、A7III、A7RII、A7II、A6600、A6500、A6400、A6300 和 A6100 上受支持。
连续视频自动对焦仅在高级模式下起作用，但性能可能不令人满意。
在索尼A9上，仅支持相位检测自动对焦。对比度检测自动对焦可能无法令人满意。
如果镜头加上任何EF增距镜或其他增距镜的较大光圈在增强前小于f / 8或在增强后小于f / 5.6，则自动对焦可能无法工作。
前几次自动对焦尝试用于校准镜头，因此可能无法成功锁定目标。再次半按快门释放按钮，自动对焦将成功锁定。
自动对焦可能难以锁定非常接近镜头较近对焦距离的拍摄对象。
自动对焦精度在很大程度上取决于镜头的设计和工作条件。具有隐藏问题的镜头在佳能数码单反相机上可能不明显，将导致索尼的自动对焦不准确和不可靠。我们看到的此类典型问题包括不平滑/不稳定的自动对焦机制（例如，间歇性地卡在某个对焦距离上），距离编码器故障/磨损或其他故障/磨损的内部传感器。

其他

不支持镜头校正，例如周边阴影、CA 和失真。
不支持使用佳能电影镜头（如CN-E 18-80mm T4.4）进行静态摄影。（功能正常，但比为静态摄影设计的镜头慢。
某些EF卡口镜头在光圈变化和自动对焦期间可能会发出可听见的噪音，在视频录制期间，相机的内置麦克风可能会拾取这些噪音。建议使用外部麦克风。然而，较近推出的一些佳能品牌镜头非常安静。
早期腾龙VC镜头，如AF 28-300/3.5-6.3 XR Di VC LD非球面[IF]微距（型号A20），AF 18-270/3.5-6.3 Di II VC LD非球面[IF]微距（型号B003），SP AF 17-50mm F/2.8 XR Di II VC LD ASPICAL [IF]（型号B005）可能无法在OIS和IBIS之间自由切换，因为它们可能无法报告IS活动状态。后来配备USD或PZD对焦电机的腾龙VC镜头就可以了。
某些售后电池手柄可能会导致光圈错误更改。这是售后电池手柄中的一个错误，但不是由Metabones速度助推器引起的。关闭售后电池手柄或使用原装索尼电池手柄。

Notes :

Lenses marked with an asterisk support smooth iris.
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.
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.
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.
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.
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.

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.
