相机镜头上的所有字母，首字母缩写和数字代表什么？

A quick peek at the barrel of your camera’s lens reveals a jungle of letters, numbers, and acronyms. What exactly do they all mean and how can you translate the codes into useful information?

快速浏览一下相机镜头的镜筒，就会发现字母，数字和首字母缩写的丛林。它们到底意味着什么，您又如何将代码转换为有用的信息？

问题 (The Question)

Photography Exchange reader Mikal Sundberg is curious about the markings on his camera lens. He writes:

摄影交流读者Mikal Sundberg对他的相机镜头上的标记感到好奇。他写：

Then looking at a lens name there is a lot of acronyms in the name describing it’s features (often specific to the manufacturer).

然后，在查看镜头名称时，会在名称中有很多首字母缩写词来描述其功能(通常特定于制造商)。

Examples, Nikon: Nikon AF-S DX 16-85mm VR f/3.5-5.6G IF-ED Nikon AF-I 600mm f/4D IF-ED Nikon AF-S VR Micro-NIKKOR 105mm f/2.8G IF-ED

Examples, Canon: Canon EF 85mm f1.2L USM Mark II Canon 70-300mm f/4.5-f/5.6 DO IS

佳能示例：佳能EF 85mm f1.2L USM Mark II佳能70-300mm f / 4.5-f / 5.6 DO IS

Examples, Sigma: Sigma 150mm F2.8 EX APO DG HSM Macro Sigma 70-200mm F2.8 EX DG OS HSM Sigma 50-150mm F2.8 EX DC APO HSM II

例如Sigma： Sigma 150mm F2.8 EX APO DG HSM Macro Sigma 70-200mm F2.8 EX DG OS HSM Sigma 50-150mm F2.8 EX DC APO HSM II

How do I decipher the lens names from different manufacturers?

如何解密不同制造商的镜头名称？

So what kind of decoder ring do you need to make sense of the code?

那么，您需要哪种解码器环才能理解代码？

答案 (The Answers)

Photography Exchange contributor Jrista offers up a very comprehensive answer. We won’t judge you if you skim through his expansive write up until you find your specific brand of camera equipment.

摄影交流撰稿人Jrista提供了一个非常全面的答案。在您找到特定品牌的摄像设备之前，我们不会判断您是否浏览了他的大量文章。

镜头仅适用于缩框数码单反相机 (Lenses only for reduced frame DSLRs)

Most low to mid range DSLRs have a sensor that is smaller than a 35mm film frame – sometimes called “reduced frame” or “cropped sensor”. So using a “full frame” lens will mean lots of extra light around the sensor that isn’t used. You can makes lenses smaller and lighter by reducing the projected image size to fit the sensor size. However using these lenses on a full frame camera would result in the corners of the image being dark – and mostly these lenses won’t fit on a full frame camera.

大多数中低端数码单反相机都具有小于35mm胶卷镜框的传感器-有时称为“缩小镜框”或“裁剪传感器”。因此，使用“全画幅”镜头将意味着传感器周围有大量多余的光未被使用。通过缩小投影图像尺寸以适合传感器尺寸，可以使镜头更小，更轻。但是，在全画幅相机上使用这些镜头会导致图像的角落变暗-而且大多数这些镜头不适合在全画幅相机上使用。

The “less than full frame” codes are:

“小于全帧”代码是：

Canon: EF-S (EF for full frame)

佳能： EF-S (全画幅EF)

Nikon: DX (FX for full frame)

尼康： DX (FX为全画幅)

Pentax: DA (FA or D FA for full frame)

宾得： DA (全画幅为FA或D FA)

Sigma: DC (DG for full frame)

Sigma： DC (全画幅DG)

Sony/Minolta: DT

索尼/美能达： DT

Tamron: Di II (Di for full frame)

腾龙： Di II (Di为全画幅)

影像稳定/减震 (Image Stabilisation/Vibration Reduction)

Image Stabilisation is also called Optical Stabilisation, Optical Image Stabilisation, Optical Steady Shot, Vibration Compensation and Vibration Reduction. Does what it says on the tin basically. (Although note that some DSLR bodies have a form of vibration reduction in the body and so don’t need it in the lens).

图像稳定也称为光学稳定，光学图像稳定，光学稳定拍摄，振动补偿和减震。基本上按锡说。 (尽管请注意，某些DSLR机身在机身上具有减震的形式，因此不需要在镜头中使用)。

快速安静的聚焦马达 (Fast and Quiet Focussing Motors)

The focussing motors in some lower end lenses can be quite noisy. The higher end lenses are able to focus more quickly (the movements can be more accurately controlled) and are quieter and use less battery. The acronym for it usually includes “Sonic”:

一些较低端镜头中的聚焦马达可能会非常嘈杂。较高端的镜头能够更快地对焦(可以更精确地控制运动)，并且更安静并且消耗更少的电池。它的首字母缩写通常包括“ Sonic”：

镜头功能(Lens Features)

There are a variety of lens features to reduce chromatic abberations (where different colours don’t exactly converge) and other imperfections in lens performance. In particular

镜头具有多种功能，可减少色差(不同的颜色不能完全融合)和镜头性能的其他缺陷。特别是

aspherical lens elements have a more complex surface profile that can reduce or eliminate spherical aberration and also reduce other optical aberrations compared to a simple lens.

与简单透镜相比，非球面透镜元件具有更复杂的表面轮廓，可以减少或消除球面像差，还可以减少其他光学像差。

low dispersion glass means that there is a relatively small difference in the amount different colours bend while going through the glass (technically the refractive index does not vary so much with wavelength), which reduces chromatic aberration.

低色散玻璃意味着穿过玻璃时不同颜色的弯曲量存在相对较小的差异(技术上折射率不会随波长变化太大)，从而降低了色差。

apochromatic lens elements are very good at reducing chromatic aberration – they are generally made up of three different materials stuck together.

复消色差透镜元件在降低色差方面非常出色–它们通常由粘在一起的三种不同材料组成。

镜片镀膜(Lens Coatings)

There are a variety of lens coatings used to reduce internal reflections and other possible problems. Internal reflections can end up producing ghost images or adding to lens flare. Not all lens manufacturers specify the lens coatings they use.

有多种用于减少内部反射和其他可能问题的镜片涂层。内部反射会最终产生重影或增加镜头光晕。并非所有镜片制造商都指定他们使用的镜片涂层。

巨集 (Macro)

Macro lenses can focus very close to the end of the lens, providing (at least) a 1:1 ratio between the size of the object and the size of the image on the sensor. In plain english, you can take very close up shots of flowers, insects and so on. They are just called Macro (or occasionally Micro), making life easy for once.

微距镜头可以非常靠近镜头的末端聚焦，从而在物体的尺寸和传感器上图像的尺寸之间提供(至少)1：1的比例。用普通的英语，您可以非常近距离地拍摄花朵，昆虫等的照片。它们被称为Macro (有时称为Micro )，使生活一次变得轻松。

专注 (Focusing)

This includes Internal/Inner Focusing (IF) and (Internal) Rear Focusing (RF or IRF). Both of these reduce the number of individual lenses moving inside the lens. They also mean that the front of the lens will not move in or out, or rotate, during focusing. The lack of rotation can be important if, say, you have a circular polarizing filter, or a graded ND filter fitted to the lens. And the front not moving in or out can be important if the lens is very close to the subject.

这包括内部/内部聚焦( IF )和(内部)后聚焦( RF或IRF )。这两者都减少了在透镜内部移动的单个透镜的数量。它们还意味着在聚焦过程中，镜头的前部不会移入或移出或旋转。例如，如果您在镜头上装有圆偏光滤镜或渐变ND滤镜，则不旋转的问题就很重要。如果镜头离拍摄对象很近，则正面不向内或向外移动可能很重要。

高端镜片 (High End Lenses)

Some manufacturers have a code to indicate their high end lenses:

一些制造商有一个代码来指示其高端镜片：

Canon: L Luxury

佳能： L Luxury

Pentax: * and Limited

宾得：*和限量

Sigma: EX Professional EXternal lens body finishing

适马： EX Professional外置镜头镜身

Sony: G Gold Series

索尼： G金系列

Tamron: SP Super Performance

腾龙： SP超级性能

杂(Miscellaneous)

Other codes might indicate the mount type (which will indicate whether it will fit your body), whether it will work with a Teleconverter or whether the lens needs the camera body to provide the motor for auto-focussing.

其他代码可能会指示安装类型(将指示其是否适合您的身体)，它是否可以与增距镜一起使用或镜头是否需要相机机身为自动对焦提供马达。

Note that I’m not an expert at this and am happy to integrate clarifications left in comments.
