3d鏡頭 適配

Canon佳能

Mirrorless cameras aren’t the future, they’re the present. If you’re switching from an older DSLR, though, the obvious thing to do is just buy an adapter so you can keep using your old gear.

無反光鏡相機(jī)不是未來，而是現(xiàn)在。 不過，如果您要從舊的DSLR切換到，則顯而易見的事情就是購(gòu)買適配器，這樣您就可以繼續(xù)使用舊的設(shè)備。

鏡頭轉(zhuǎn)接器的優(yōu)點(diǎn) (The Advantages of a Lens Adapter)

The biggest advantage of lens adapters is pretty clear: they enable you to use your existing collection of lenses on your new camera. With many mirrorless cameras starting at over $1,000, anything that offsets the cost of switching is much appreciated. After all, mirrorless lenses cost as much as the new camera body.

鏡頭適配器的最大優(yōu)勢(shì)非常明顯：它們使您能夠在新相機(jī)上使用現(xiàn)有的鏡頭系列。 由于許多無反光鏡相機(jī)的起價(jià)都在1,000美元以上，因此能夠抵消轉(zhuǎn)換成本的任何事物都倍受贊賞。 畢竟，無反光鏡鏡頭的價(jià)格與新相機(jī)的價(jià)格一樣。

For most photographers, simultaneously switching systems and replacing all their DSLR lenses with their mirrorless equivalents would cost more than they can justify spending.

對(duì)于大多數(shù)攝影師而言，同時(shí)切換系統(tǒng)并用無反光鏡的同等品替代其所有DSLR鏡頭所花費(fèi)的成本超過其合理的花費(fèi)。

So, as the upside of a lens adapter is pretty clear, are there any downsides?

因此，由于鏡頭適配器的優(yōu)點(diǎn)很明顯，是否有缺點(diǎn)？

為什么需要鏡頭轉(zhuǎn)接器 (Why Lens Adapters Are Necessary)

Mirrorless cameras aren’t just DSLRs without the mirror—they’re a totally overhauled platform. Both Canon and Nikon took the opportunity to radically redesign their decades-old lens mounts, and with good reason. Canon debuted the EF mount in 1987, while Nikon’s F mount has been around since 1959.

無反光鏡相機(jī)不只是沒有反光鏡的數(shù)碼單反相機(jī)-它們是一個(gè)全面檢修的平臺(tái)。 佳能和尼康都趁機(jī)從根本上重新設(shè)計(jì)了它們已有數(shù)十年歷史的鏡頭卡口。 佳能于1987年推出了EF卡口，而尼康的F卡口自1959年以來就已面世。

Canon佳能

The most noticeable change is that the lens mounts are now bigger, and the rear lens elements sit closer to the image sensor. Of course, the actual mount connection has changed, too.

最明顯的變化是鏡頭座現(xiàn)在更大了，后鏡頭元件更靠近圖像傳感器。 當(dāng)然，實(shí)際的安裝連接也已更改。

This means lens adapters are necessary because the lens mounts on mirrorless cameras are entirely different from the DSLR mounts they succeed. Canon’s RF mount isn’t just an updated EF—it’s new.

這意味著鏡頭適配器是必需的，因?yàn)闊o反光鏡相機(jī)上的鏡頭座與成功的DSLR座完全不同。 佳能的RF卡口不僅是更新的EF，而且還是新的。

鏡頭轉(zhuǎn)接器增加了尺寸，重量和麻煩 (Lens Adapters Add Size, Weight, and Hassle)

Nikon尼康

Lens adapters add physical size and weight to your lenses. It’s not a huge amount, but if you’re buying a mirrorless camera because you want a smaller, lighter setup, this is something to consider. For example, Canon’s most basic EF-EOS R adapter adds an extra inch and four ounces to any lens you use. Nikon’s FTZ adapter adds a bit more weight and bulk because of its tripod mount.

鏡頭適配器可增加鏡頭的實(shí)際尺寸和重量。 這不是一個(gè)很大的數(shù)目，但是如果您要購(gòu)買無反光鏡相機(jī)是因?yàn)槟胍?#xff0c;更輕的設(shè)置，則需要考慮這一點(diǎn)。 例如，佳能最基本的EF-EOS R適配器為您使用的任何鏡頭增加了1英寸和4盎司。 尼康的FTZ適配器由于安裝在三腳架上而增加了重量和體積。

In addition to the size and weight penalty, a lens adapter is simply one more thing you have to remember to take with you on a shoot. If you forget it, you won’t be able to take any photos.

除了體積和重量上的損失外，鏡頭轉(zhuǎn)接器還只是拍攝時(shí)要記住的另一件事。 如果忘記了，將無法拍照。

相容性問題 (Compatibility Issues)

If you switch from a Canon DSLR to a Canon mirrorless camera, and also use a Canon lens adapter, things are pretty sweet. You should be able to use all your lenses happily. If not, though, things get a bit more complicated.

如果您從佳能數(shù)碼單反相機(jī)切換到佳能無反光鏡相機(jī)，并且還使用佳能鏡頭適配器，一切都會(huì)非常好。 您應(yīng)該能夠愉快地使用所有鏡頭。 如果不是這樣，事情會(huì)變得更加復(fù)雜。

Even if you switch from a Nikon DSLR to a Nikon mirrorless camera, and use a Nikon lens adapter, there are some compatibility issues. Most newer lenses should be fine, as they have built-in autofocus motors. However, because the adapter doesn’t have one, Nikon’s AF and AF-D lenses are manual focus only.

即使從尼康DSLR切換到尼康無反光鏡相機(jī)并使用尼康鏡頭轉(zhuǎn)接器，也存在一些兼容性問題。 大多數(shù)較新的鏡頭都應(yīng)該不錯(cuò)，因?yàn)樗鼈兙哂袃?nèi)置的自動(dòng)對(duì)焦馬達(dá)。 但是，由于該適配器沒有一個(gè)，因此尼康的AF和AF-D鏡頭僅是手動(dòng)對(duì)焦。

With some older lenses, there’s also no automatic aperture control, which means no electronic metering, automatic exposure modes, or EXIF data.

對(duì)于某些較舊的鏡頭，也沒有自動(dòng)光圈控制，這意味著沒有電子測(cè)光，自動(dòng)曝光模式或EXIF數(shù)據(jù)。

And that’s even if you stay with the same brand. If you want to mount a Nikon DSLR lens to a Canon mirrorless camera, you’ll need a pricey adapter to get even a fully manual experience.

即使您使用同一品牌，也是如此。 如果要將尼康DSLR鏡頭安裝到佳能無反光鏡相機(jī)上，則需要昂貴的適配器才能獲得完全手動(dòng)的體驗(yàn)。

With Canon, though, there are EF-to-other-brand adapters available for pretty much every platform. Photographer?Ken Rockwell even claimed he’s had better results using Canon’s DSLR lenses instead of Nikon’s on his Nikon mirrorless.

但是，有了佳能，幾乎每個(gè)平臺(tái)都可以使用EF至其他品牌的適配器。 攝影師肯·洛克威爾(Ken Rockwell)甚至聲稱，使用佳能的DSLR鏡頭比使用尼康無反光鏡的尼康鏡頭效果更好。

Put simply, though, just because an adapter exists doesn’t mean you’ll have an easy (or pleasant) time switching—especially if you’re mixing brands. Generally, cheaper adapters will give you only manual control. They can also prevent features like image stabilization from working.

簡(jiǎn)而言之，僅因?yàn)榇嬖谶m配器并不意味著您將有一個(gè)輕松(或愉快的)時(shí)間切換-特別是如果您混合使用品牌。 通常，便宜的適配器只會(huì)給您手動(dòng)控制。 它們還可以防止圖像穩(wěn)定等功能起作用。

Make sure you research the specific trade-offs you’ll have to accept before committing to a new system.

在提交新系統(tǒng)之前，請(qǐng)確保您研究了必須接受的具體折衷方案。

自動(dòng)對(duì)焦可能會(huì)變慢 (Autofocus Might Be Slower)

DSLRs and mirrorless cameras autofocus?a bit differently. DSLRs have dedicated focus sensors, while mirrorless cameras generally rely on sensors built into the imaging sensor. Naturally, mirrorless lenses are designed to work with the focus on mirrorless cameras, while DSLR lenses are designed to work with DSLRs.

單反相機(jī)和無反光鏡相機(jī)的自動(dòng)對(duì)焦有些不同。 DSLR具有專用的聚焦傳感器，而無反光鏡相機(jī)通常依賴于內(nèi)置在成像傳感器中的傳感器。 自然地，無反光鏡鏡頭旨在與無反光鏡相機(jī)對(duì)焦，而單反相機(jī)鏡頭則設(shè)計(jì)用于與單反相機(jī)。

This means if you’re using a lens with an adapter, you might notice it autofocuses slower than it did on your DSLR or with an equivalent mirrorless lens. This is especially noticeable when you’re trying to focus on fast-moving subjects or action shots.

這意味著，如果您使用帶適配器的鏡頭，可能會(huì)發(fā)現(xiàn)它的自動(dòng)對(duì)焦速度比DSLR或等效的無反光鏡鏡頭慢。 當(dāng)您嘗試聚焦于快速移動(dòng)的主體或動(dòng)作鏡頭時(shí)，這一點(diǎn)尤其明顯。

Of course, it’s always ideal if you can replace your DSLR lenses with the equivalent mirrorless lenses for your new mirrorless camera. Unless you’ve got a lot of cash to burn, though, a lens adapter can definitely be a worthwhile trade-off.

當(dāng)然，如果可以用與新無反光鏡相機(jī)相當(dāng)?shù)臒o反光鏡鏡頭替換DSLR鏡頭，那將永遠(yuǎn)是理想的選擇。 但是，除非您有大量現(xiàn)金可以消耗，否則鏡頭轉(zhuǎn)接器絕對(duì)是一個(gè)值得權(quán)衡的選擇。
