愛普生第三方相機_值得購買第三方相機鏡頭嗎？

愛普生第三方相機

When people buy a Canon or Nikon camera, they often assume that they can only buy Canon or Nikon lenses. But that isn’t true. While Nikon lenses won’t work on your Canon camera, there are third-party lens manufacturers—such as Sigma, Tamron, Tokina, Samyang (also sold as Rokinon), Opteka, Yongnuo and Zeiss—that make lenses for Canon, Nikon, and sometimes Sony and other cameras. But are they any good?

人們購買佳能或尼康相機時，通常會認為只能購買佳能或尼康鏡頭。但這不是事實。雖然尼康鏡頭無法在佳能相機上使用，但仍有一些第三方鏡頭制造商(例如Sigma，騰龍，Tokina，三陽(也以Rokinon出售)，Opteka，Yongnuo和Zeiss)為佳能，尼康，有時還有Sony和其他相機。但是它們有什么好處嗎？

The short answer is that, yes, in some cases, third-party lenses are well worth buying. They can offer features that Canon or Nikon doesn’t offer, such as longer zoom lenses, faster apertures, or better bang for your buck. However, third-party lenses are not universally a good deal. Like most products, there are good ones, and incredibly cheap ones that we wouldn’t recommend.

簡短的答案是，是的，在某些情況下，值得購買第三方鏡頭。他們可以提供佳能或尼康沒有的功能，例如更長的變焦鏡頭，更快的光圈或更好的性價比。但是，第三方鏡頭并不是一件好事。像大多數產品一樣，有一些不錯的產品，而我們不推薦的那些價格非常便宜的產品。

好的鏡片很貴，沒關系的人 (Good Lenses Are Expensive, No Matter Who Makes Them)

The unfortunate reality is that no matter what, good lenses aren’t cheap. There are a lot of incredibly finely made optical parts that go into a lens. There’s often a lot of manual work as well which pushes the cost up further. This is true whether you’re buying a lens from Canon or Tamron.

不幸的現實是，無論如何，好的鏡頭并不便宜。鏡頭中有很多非常精細的光學部件。通常還有很多手動工作，這進一步推高了成本。無論您是從佳能還是騰龍購買鏡頭，都是如此。

This doesn’t mean that there aren’t price differences, though. For example, the 70-200mm f/2.8 is a very popular zoom lens. It’s perfect for a lot of different kinds of photography, from sports to portraiture. Canon’s own 70-200mm f/2.8L IS II retails for $1,949. Tamron offers a similar lens, the SP 70-200mm f/2.8 Di VC for $1,299. Sigma also makes a 70-200 f/2.8 for the same price.

不過，這并不意味著沒有價格差異。例如，70-200mm f / 2.8是非常受歡迎的變焦鏡頭。從運動到肖像攝影，它非常適合各種攝影。佳能自己的70-200mm f / 2.8L IS II零售價為1,949美元。騰龍也提供類似的鏡頭， SP 70-200mm f / 2.8 Di VC ，現價$ 1,299。 Sigma還以相同的價格生產了70-200 f / 2.8。

By going with the Tamron or Sigma, you’re saving $650, but you’re still spending a lot on the lens as a whole. You’re also giving up some image quality as you can see in the video review above. If you want the absolute best lens, you have to buy the Canon; but if price is more of an issue, then the third-party lenses start to look very tempting.

通過使用騰龍或西格瑪，您可以節省650美元，但從整體上看，您仍在鏡頭上花費很多。您還放棄了一些圖像質量，如上面的視頻評論所示。如果您想要絕對最好的鏡頭，則必須購買佳能。但是如果價格更成問題，那么第三方鏡頭就開始顯得很誘人。

This is repeated across lots of different categories. Canon’s EF 85mm f/1.4L IS is $1,599 and Nikon’s AF-S FX NIKKOR 85mm f/1.4G is $1,596, while the incredibly well regarded Sigma 85mm f/1.4 DG HSM Art is $1,199 for both Canon and Nikon. You’re not saving thousands of dollars, but you’re not saving an insignificant sum either.

在許多不同類別中重復此操作。佳能的EF 85mm f / 1.4L IS為1,599美元，尼康的AF-S FX尼克爾85mm f / 1.4G為1,596美元，而廣受好評的Sigma 85mm f / 1.4 DG HSM Art，佳能和尼康的價格均為1,199美元。您不會省下數千美元，但是您也不會省去微不足道的款項。

The odds are if you’re looking for a common enough lens, there will be an original manufacturer option as well as a few third-party ones. The good third-party lenses will still be expensive (expect to pay somewhere north of two thirds of the price of the manufacturer’s offering), but are probably better value for money. Do a bit of research to check that you don’t lose too much image quality, but otherwise, you’re pretty safe with a good third-party lens.

如果您正在尋找足夠通用的鏡頭，則可能會有原始制造商選項以及一些第三方選項。好的第三方鏡片仍然會很昂貴(期望支付制造商產品價格三分之二的價格)，但可能物有所值。做一些研究，以確保您不會損失太多的圖像質量，但是，否則，使用良好的第三方鏡頭是非常安全的。

第三方鏡頭為您提供更多選擇 (Third Party Lenses Give You More Options)

While Canon and Nikon both have very mature lens product lines, there are still a few gaps where, if you want a certain kind of lens, you need to go third-party. The case is even more obvious with Sony’s recent mirrorless camera range. While the cameras are awesome and incredibly popular, they just don’t have every lens you could possibly need. This means a lot of people turn to third-party manufactuers.

佳能和尼康都有非常成熟的鏡頭產品線，但是如果您想要某種鏡頭，則仍然需要一些第三方。索尼最近的無反光鏡相機系列的情況更加明顯。雖然這些相機超贊且令人難以置信，但它們只是沒有您可能需要的所有鏡頭。這意味著很多人轉向第三方制造商。

Let’s look at an example. For good astrophotography, you want a wide angle lens with a wide aperture. One thing you don’t need, however, is autofocus; it just doesn’t work at night.

讓我們來看一個例子。為了獲得良好的天文攝影，您需要具有大光圈的廣角鏡頭。但是，您不需要的一件事就是自動對焦。只是晚上不工作。

For these reasons, Rokinon makes some of the most popular astrophotography lenses. Their 24mm f/1.4 is just $549.00. It doesn’t have autofocus, so it’s not great for anything other than astrophotography or landscape photography, but it’s a wide angle lens with a really wide aperture. Canon’s equivalent lens, the EF 24mm f/1.4L II, since it has autofocus, is a lot more versatile; but at $1,549 it’s almost three times the price for no real improvement in image quality. Sure, you can do some street photography, but if you’re just interested in shooting the Milky Way, that isn’t a selling point.

由于這些原因，Rokinon制造了一些最受歡迎的天文攝影鏡頭。他們的24mm f / 1.4僅售549.00美元。它沒有自動對焦功能，因此除了用于天文攝影或風景攝影之外，其他功能都不是什么好選擇，但是它是具有非常大光圈的廣角鏡頭。佳能的等效鏡頭EF 24mm f / 1.4L II具有自動對焦功能，因此用途更加廣泛。但價格為1,549美元，幾乎是真正提高圖像質量的價格的三倍。當然，您可以做一些街頭攝影，但是，如果您只是想拍攝銀河系，那不是賣點。

If you’re prepared to give up on certain features like autofocus or image stabilization, or buy a prime lens rather than a zoom lens, third-party manufacturers give you a lot more options. For astrophotographers, Rokinon has wide angle, wide aperture manual focus lenses available with focal lengths of 8mm, 14mm, 16mm, 24mm, and 35mm. You just can’t beat that kind of choice.

如果您準備放棄某些功能(例如自動對焦或圖像穩定)，或者購買定焦鏡頭而不是變焦鏡頭，那么第三方制造商將為您提供更多選擇。對于天文攝影師，Rokinon提供廣角，大光圈手動對焦鏡頭，焦距分別為8mm，14mm，16mm，24mm和35mm。您就是無法擊敗這種選擇。

當心廉價鏡片 (Watch Out for the Cheap Lenses)

While so far, I’ve been focusing on the positive side of third-party lenses, there is also utter crap out there. Take this Opteka 500mm f/8 lens with a built in 2x teleconverter; it costs just $89.95. Crazy, right? What a deal!

到目前為止，我一直專注于第三方鏡頭的積極方面，但也有很多廢話。這款帶內置2倍增距鏡的Opteka 500mm f / 8鏡頭；只需$ 89.95。瘋狂吧？太好了！

Except…no. The reason the lens is so cheap is because Opteka cut some serious corners. Not only are the image and build quality poor, but the maximum aperture of f/8 just isn’t wide enough to get the sort of shutter speeds you need to use such a long telephoto lens. Also, since it’s a manual focus lens, you won’t be able to react quickly to any situations, which makes it useless for sports or wildlife photography—the two situations where photographers normally use long telephoto lenses. About the only thing this lens is good for is taking bad photos of the moon. Even at less than $90, it’s a ripoff.

除了……不。鏡頭如此便宜的原因是因為Opteka犯了一些嚴重的錯誤。不僅圖像和結構質量差，而且f / 8的最大光圈還不夠寬，無法獲得使用這么長的長焦鏡頭所需的快門速度。另外，由于它是手動對焦鏡頭，您將無法對任何情況做出快速React，這使它在體育或野生動物攝影中無用，這是攝影師通常使用長焦鏡頭的兩種情況。這種鏡頭唯一的好處就是對月球拍攝不好的照片。即使價格不到90美元，這也是一個騙子。

Similarly, you can get a Yongnuo 50mm f/1.8 for $49.99. That’s super cheap and it’s not an awful lens, but a genuine Canon EF 50mm f/1.8 is only $125. And for the extra $75, you get much better build, optical, and autofocus quality.

同樣，您可以以49.99美元的價格購買Yongnuo 50mm f / 1.8 。那是超級便宜，而且不是可怕的鏡頭，但是真正的佳能EF 50mm f / 1.8僅售125美元。額外支付75美元，您將獲得更好的構建，光學和自動對焦質量。

When it comes down to it, good third-party lenses offer you more options at competitive (although still expensive) prices; bad third-party lenses aren’t worth the cost of shipping.

歸根結底，優質的第三方鏡頭可為您提供更具競爭力(盡管仍然很昂貴)的價格的更多選擇。劣質的第三方鏡片不值運費。

As long as you buy from a reputable third-party manufacturer like Sigma, Tamron, Tokina, Samyang/Rokinon, or Zeiss, you’re not likely to go too far wrong. On the other hand, if you buy from the likes of Opteka or Yongnuo, you’re probably going to be disappointed. In all cases, the best thing to do is research the lens you want to buy before spending any money.

只要您從Sigma，Tamron，Tokina，Samyang / Rokinon或Zeiss等著名的第三方制造商那里購買產品，您就不會出錯。另一方面，如果您從Opteka或Yongnuo等商店購買商品，您可能會感到失望。在所有情況下，最好的辦法是在花任何錢之前先研究要購買的鏡頭。
