Mirrorless cameras are proving more and more popular. As they’ve developed in the last few years, they’ve become really useful in certain circumstances.
事实证明，无反光镜相机越来越受欢迎 。 随着它们在过去几年中的发展，它们在某些情况下已经变得非常有用。
One of the really interesting features of mirrorless cameras is, due to their design, you can use new and old lenses from different manufacturers with an appropriate adapter. This is thanks to the “flange distance” which is the distance between the lens mount and the film plane. Most DSLRs and SLRs have very similar flange distances (around 45mm) which means that any adapter would need to be unworkably thin. Mirrorless cameras, however, have a flange distance of about 20mm. This give manufacturers a lot of room to play with. So, let’s look at how to go about using any lens on your mirrorless camera.
无反光镜相机的真正有趣的功能之一是，由于其设计，您可以通过适当的适配器使用来自不同制造商的新旧镜头。 这要归功于“凸缘距离”，即镜头座与胶片平面之间的距离。 大多数数码单反相机和单反相机的法兰距离非常相似(约45毫米)，这意味着任何适配器都必须薄得无法工作。 但是，无反光镜相机的法兰距离约为20mm。 这为制造商提供了很大的发挥空间。 因此，让我们看看如何在无反光镜相机上使用任何镜头。
购买具有正确安装座的第三方镜头 (Buy Third Party Lenses With the Correct Mount)
The simplest way to use different lenses with your mirrorless camera doesn’t actually need any adapter: just buy lenses from third-party manufacturers that come with the correct mount. For example, Sony’s Alpha series of cameras use the E-mount. Sigma, Tokina, Voigtlander, and Zeiss all make a range of E-mount lenses that will just work with your camera.
在无反光镜相机上使用不同镜头的最简单方法实际上不需要任何适配器：只需从第三方制造商处购买 具有正确安装座的镜头 。 例如，索尼的Alpha系列相机使用E卡口。 Sigma，Tokina，Voigtlander和Zeiss都制造了一系列适用于您的相机的E卡口镜头。
One thing to watch out for; some of the lenses, like the Zeiss Loxia 35mm f/2, will be E-mount but manual focus. This means you won’t be able to use your camera’s autofocus features.
要提防的一件事； 某些镜头(例如Zeiss Loxia 35mm f / 2 )将进行E卡口但手动对焦。 这意味着您将无法使用相机的自动对焦功能。
Unfortunately, the range of third-party lenses that are available for mirrorless cameras still doesn’t come near the amount available to DSLRs.
不幸的是，可用于无反光镜相机的第三方镜头的范围仍然不及单反相机可用的数量。
为旧的手动对焦镜头购买便宜的转接器 (Buy a Cheap Adapter for Old Manual Focus Lenses)
Old manual focus lens with manual aperture controls are the easiest lenses to get working with your mirrorless camera. The adapters are really just dumb bits of metal (or plastic) that adjust the flange distance so that the lens can focus on the mirrorless camera’s film plane. You won’t have autofocus or electronic aperture control, but otherwise they’ll work just fine.
具有手动光圈控制功能的老式手动对焦镜头是与无反光镜相机一起使用时最容易使用的镜头。 适配器实际上只是傻瓜金属(或塑料)，它们可以调节法兰距离，以便镜头可以聚焦在无反光镜相机的胶片平面上。 您将没有自动对焦或电子光圈控制，但否则它们将正常工作。
This means that pretty much any lens made before 1985 (after that, camera manufacturers started really getting into electronic controls) is your best bet. You can also use Nikon and Pentax autofocus lenses that still have aperture rings, such as the Nikon AF FX NIKKOR 50mm f/1.8D, but again, you’ll have to use them without autofocus.
这意味着，在1985年之前制造的几乎所有镜头(此后，相机制造商开始真正涉足电子控制)都是您最好的选择。 您也可以使用仍然具有光圈环的尼康和宾得自动对焦镜头，例如Nikon AF FX NIKKOR 50mm f / 1.8D ，但同样，您必须在没有自动对焦的情况下使用它们。
The combination of adapters, lenses, and cameras is way too wide here for me to make any solid recommendations. Instead, you should try and find a well reviewed, inexpensive metal adapter that is compatible with the lens mount and the camera mount. For example, this $14.95 adapter from Fotodiox fits the bill perfectly for connecting the Nikon lens I mentioned earlier to a Sony Alpha camera.
适配器，镜头和相机的组合在这里太宽了，我无法提出任何可靠的建议。 取而代之的是，您应该尝试找到一种经过全面检查的廉价金属适配器，该适配器与镜头座和相机座兼容。 例如， 这款来自Fotodiox的$ 14.95适配器非常适合将我之前提到的尼康镜头连接到Sony Alpha相机。
购买用于现代镜片的“智能”转接器 (Buy a “Smart” Adapter for Modern Lenses)
If you want to use modern autofocus lenses with electronic controls with your mirrorless cameras, then a dumb bit of metal just won’t cut it. Instead, you need to look for adapters that also connect the electronics in the lens and camera body.
如果您想在无反光镜相机上使用带有电子控制功能的现代自动对焦镜头，那么笨拙的金属将无法切割。 相反，您需要寻找还可以连接镜头和相机机身中电子元件的适配器。
There are a wide range of smart adapters available, but the most popular combination is connecting Canon’s EF-mount lenses to Sony’s E-mount mirrorless cameras. If you’re considering buying a mirrorless system and want to have the most options, that’s the way to go. At the low end, you can get a Fotodiox Pro Fusion Adapter for $99.95, while at the high end there is the Metabones Canon EF Lens to Sony E Mount Smart Adapter (Fifth Generation) for $399. Both adapters do largely the same thing, although the Metabones adapter has a few extra features to give you more control over how the lens and camera work together.
有各种各样的智能适配器可用，但是最受欢迎的组合是将佳能的EF卡口镜头连接到索尼的E卡口无反光镜相机。 如果您正在考虑购买无反光镜系统并希望拥有最多的选择，那就是您的最佳选择。 在低端，您可以以99.95美元的价格获得Fotodiox Pro Fusion适配器 ，而在高端，则是399美元的Metabones佳能EF镜头至Sony E卡口智能适配器(第五代) 。 尽管Metabones适配器具有一些额外的功能，使您可以更好地控制镜头和相机的协作方式，但这两个适配器在很大程度上都具有相同的功能。
For every other combination, I’d recommend you look for a Fotodiox adapter if you’re budget conscious or a Metabones adapter if you want something closer to the top end. If you can’t find one, then the best advice I can give is do a bit of research and buy the best reviewed adapter at the price you want to pay. Expect to pay between $100 and $500 for most set ups.
对于其他所有组合，如果您有预算意识，建议您选择Fotodiox适配器；如果您想要更接近高端的产品，则建议使用Metabones适配器。 如果找不到，那么我能提供的最佳建议是进行一些研究，然后以您希望支付的价格购买经过最佳评估的适配器。 预计大多数设置的费用在$ 100到$ 500之间。
关于加速器的注意事项 (A Note on Speed Boosters)
As well as straight up adapters, if you’re researching how to connect different lenses to mirrorless cameras you’ll run into “Speed Boosters”. As well as connecting the lens to the camera, they also increase its maximum aperture. There are, however, several downsides.
与直插式适配器一样，如果您正在研究如何将不同的镜头连接到无反光镜相机，则会遇到“ Speed Boosters”。 除了将镜头连接到相机外，它们还增加了其最大光圈。 但是，有几个缺点。
First, speed boosters are a lot more expensive than regular adapters. The Metabones Canon EF to Sony E-Mount Speed Booster (Fifth Generation) costs $649, a full $250 more than the regular adapter.
首先，速度提升器比常规适配器昂贵得多。 佳能EF到索尼E-Mount Speed Booster(第五代)的售价为649美元，比普通适配器高出250美元。
Second, speed boosters only work with crop sensor (APS-C) and Micro 4/3 mirrorless cameras. If you have a full-frame mirrorless camera you will need to use it in APS-C compatibility mode which digitally reduces the size of the sensor’s capture area.
其次，速度提升器仅与农作物传感器(APS-C)和Micro 4/3无反光镜相机一起使用。 如果您拥有全画幅无反光镜相机 ，则需要在APS-C兼容模式下使用它，以数字方式缩小传感器捕获区域的大小。
If you have an APS-C or Micro 4/3 mirrorless camera, and don’t mind the extra expense, go ahead and consider getting a speed booster adapter for a little more low light performance. On the other hand, if you have (or you’re planning to upgrade to) a full-frame mirrorless camera, or the price seems a little silly, just get a regular adapter.
如果您拥有APS-C或Micro 4/3微型无反光镜相机，并且不介意支付额外费用，请继续考虑使用速度增强器适配器，以获得更微弱的照明性能。 另一方面，如果您拥有(或打算升级至)全画幅无反光镜相机，或者价格似乎有些可笑，则只需购买常规适配器即可。
