100倍光学变焦 数码相机？英文双语对照

一、100倍光学变焦 数码相机？

如果想用100倍数码变焦拍照片，成片质量肯定非常一般，说到底100倍数码变焦噱头大于实用。

数码变焦不是一个新鲜的技术概念，十多年前的卡片机、家用DV（数码摄像机）标配数码变焦，而且动不动就上百倍。现在家用DV基本都不提数码变焦，单反相机更是拒绝和数码变焦沾上关系，简单说数码变焦这个卖点被无情抛弃了。

二、10倍光学变焦数码相机？

数码相机依靠光学镜头结构来实现变焦。数码相机的光学变焦方式与传统35mm相机差不多，就是通过镜片移动来放大与缩小需要拍摄的景物，光学变焦倍数越大，能拍摄的景物就越远。

10倍的光学变焦的镜头的焦距范围一般是

36-360mm，也有28-280mm的。也就是说最大焦距为最小焦距的10倍。

三、120倍光学变焦数码相机？

不存在120倍光学变焦数码相机。

光学变焦的倍数的计算是镜头的最长焦段除以最广角段，比如17-200mm的镜头就是200除以17，约12倍变焦。如果光学倍焦倍数很大，可以在不改变拍摄距离的情况下以拍到人物的远景、全景、中景、近景、特写等画面。用到影视摄影上，还可得到连续变焦效果的画面。

一般来说，焦距在24mm~35mm之间的镜头属于“广角镜头”，它们具有较小的焦距和较宽的视角，可以收录更广阔的空间，因此常被业内誉为“大师镜头”。 

历史上焦距最长的镜头焦距2米，实际变焦也就3倍，重近20公斤。即使除以广角焦距24mm,倍数也不到100。没有这样的镜头。

四、数码相机最高光学变焦是几倍？

数码相机最高光学变焦可以达到50倍甚至更高。因为随着科技的不断进步，相机镜头的光学变焦越来越强大，同时也有一些相机厂商采用数字变焦技术来增强变焦效果，使得相机变焦倍数更高。通过光学变焦可以使得相机在拍摄时具有更大的视角覆盖面积，从而更好的捕捉场景中细节和纹理。值得注意的是，过高的变焦倍数也会影响相片的画面质量，所以在实际使用时需要根据需求来选择合适的相机。

五、佳能100倍光学变焦数码相机？

100倍光学变焦数码相机截止目前仅仅是个专利，尚未真正成为商业化的现实产品。

扩展资料

2013年，佳能公布了一款100倍变焦镜头的专利，这个专利应该是针对1/2.3英寸传感器的长焦机型而设计，焦距为3.5-350mm，等效焦距为20-200mm。

尼康已经有83倍变焦的P900了，佳能推出了100倍变焦也不是什么问题。

佳能100倍光学变焦专利，光圈为F3.3-7.1

虽然现在一英寸相机大行其道，但是1/2.3英寸还是有一定的生存空间的，有些不太在意画质的用户还是会追求大变焦比的旅行相机。

佳能这个专利预计很快就会商业化，应该会用在下一代的长焦相机上，可能会是SX70，就让我们拭目以待吧。

六、挑选数码相机，如何选择数字变焦和光学变焦？

光学变焦 依靠光学镜头结构来实现变焦，变焦方式与传统相机设计一样，取决于镜头的焦距，是通过摄像头的镜片移动来放大与缩小需要拍摄的景物。光学变焦倍数越大，能拍摄的景物就越远。光学变焦可以支持图像主体成像后，分辨率及画质不会改变，相对清晰。数码变焦 实际上是画面的电子放大，把原来CCD影像感应器上的一部份像素使用“插值”算法将画面放大。通过数码变焦，拍摄的景物放大了，但它的清晰度会有一定程度的下降，类似与VCD或DVD中的zoom功能，只能将原先的图像尺寸裁小，让图像在LCD屏幕上变得较大，但并不会使细节更清晰，相机的最大变焦不是数字变焦和光学变焦的乘积，是相加。W290是款普通的家用机。质量不错，只要伸缩镜头不出问题可以用很久。

七、数码相机没有光学变焦和自动对焦？

这个问题本身就有点问题。

其实任何照相机本身没有光学变焦能力，光学变焦的实现是取决于他所配的镜头。

卡片机说它有光学变焦是因为镜头不可拆下（硬要拆就坏了），是连为一体的，所以说某某相机有多少倍光学变焦。单反机一般镜头是可拆换的，甚至机身和镜头是分开买的，所以单反机（指机身）是没有光学变焦的。

八、光学变焦100倍数码相机排行？

1、索尼RX10，1英寸传感器，蔡司镜头，等效24-200焦段，恒定2,8光圈画质有保证，缺点是焦段不够长；

2、松下FZ1000，1英寸传感器，徕卡镜头，等效25-400焦段，画质很好，缺点是长焦端光圈掉的有点快；

3、富士XS1，2/3英寸传感器，富士龙镜头，等效24-624焦段，画质比较好，手动变焦快捷，缺点是傻大黑粗，重量体积像单反；

九、混合光学变焦与光学变焦区别？

区别如下：

　　1、混合光学变焦是整合手机光学变焦、以及数码变焦、以及多个镜头协同、其他画质强化算法的相机算法，用于提高手机相机变焦效果。是一个系统性工程，实际表现受限于各家相机算法、以及硬件。为了更好的营销，厂商会将画质可以较好的变焦倍数包装为混合变焦倍数。

　　2、光学变焦是依靠光线折射无损画质，可以把远处的细小物体拍得跟近处一样清晰，这也是广泛应用在单反及数码相机上的技术。光学变焦是通过镜头、物体和焦点三方的位置发生变化而产生的。当成像面在水平方向运动的时候，视角和焦距就会发生变化，更远的景物变得更清晰，让人感觉像物体递进的感觉。

       显而易见，要改变视角必然有两种办法，一种是改变镜头的焦距。用摄影的话来说，这就是光学变焦。通过改变变焦镜头中的各镜片的相对位置来改变镜头的焦距。另一种是数码变焦。数码变焦，实际上是画面的电子放大 , 把原来的 CCD影像感应器上的一部分像素使 用 “ 插值 “ 手段放大 。将CCD影像感应器上的部分影像放大到整个画面。 通过数码变焦,拍摄的景物放大了，但必然会损失影像的品质。实际上数码变焦并没有改变镜头的焦距，只是通过改变成像面对角线的角度来改变视角，从而产生了“相当于”镜头焦距变化的效果。

十、数码相机的光学变焦有什么作用么？

光学变焦的数码相机在远距离变焦时，人物或事物的空间感、层次感要比数码变焦的要更好一些，但是数码变焦的产品使用是要方便一些。

光学变焦光学变焦是通过镜头、物体和焦点三方的位置发生变化而产生的。

当成像面在水平方向运动的时候，视觉和焦距就会发生变化，更远的景物变得更清晰，让人感觉像物体递进的感觉。

要改变视角必然有两种办法，一种是改变镜头的焦距。用摄影的话来说，这就是光学变焦。通过改变变焦镜头中的各镜片的相对位置来改变镜头的焦距。 所以人们看到，一些镜头越长的数码相机，内部的镜片和感光器移动空间更大，所以变焦倍数也更大。

One, camera of number of 100 times optical scorch?

If want to pile up scorch to take a picture with 100 multiple, become a quality affirmation is very general, stunt of scorch of 100 times number is more than in the final analysis practical.

Digital scorch is not a new technical idea, DV of the card machine more than 10 years ago, family expenses (digital camera) mark matchs digital scorch, and go up easily hundredfold. Family expenses DV does not carry digital scorch basically now, sheet turns over camera is to reject to touch a concern with digital scorch more, say digital scorch sold a dot this to be abandoned by callosity simply.

2, camera of number of 10 times optical scorch?

Digital camera relies on structure of optical camera lens to realize scorch. The optical scorch means of digital camera and traditional 35mm camera are about the same, come through lens shift namely enlarge and the scenery that narrow need films, optical scorch multiple is bigger, the scenery that can film is further.

The focal length limits of the camera lens of the optical scorch of 10 times is commonly

36-360mm, also have 28-280mm. That is to say 10 times what the biggest focus is the smallest focal length.

3, camera of number of 120 times optical scorch?

120 times more nonexistent camera of optical scorch number.

The diploid computation of optical scorch is camera lens is the longest anxious paragraph divide with the most extensive role paragraph, for instance the camera lens of 17-200mm is 200 divide with 17, make an appointment with 12 times scorch. If times more optical anxious multiple is very big, can not changing the picture such as the distant view that films the person reachs with patting below the circumstance of the distance, panoramic, medium shot, close shot, close-up. Use to photography of movie and TV, return the picture of effect of attainable successive scorch.

Generally speaking, focal length is belonged to in the camera lens between 24mm~35mm " wide-angle lens " , they have lesser focal length and wider perspective, can collect vaster space, accordingly constant by course of study inside praise for " Great Master camera lens " .

The camera lens focal distance with the longest focal distance on the history 2 meters, actual scorch also with respect to 3 times, weigh nearly 20 kilograms. Although divide with 24mm of extensive role focal length, multiple also is less than 100. Without such camera lens.

4, is digital camera highest and optical is scorch severalfold?

Highest and optical scorch can achieve digital camera 50 times taller even. Because of the ceaseless progress as science and technology, the optical scorch of camera camera lens is more and more powerful, at the same time also manufacturer of a few camera uses digital scorch technology to enhance scorch result, make camera scorch multiple higher. Can make through optical scorch camera has bigger perspective to cover an area when film, thereby the finer detail in catching setting and grain. Notable is, exorbitant scorch multiple also can affect the picture quality of photo, need to choose equal watch for an opportunity according to demand when be used actually so.

5, beautiful can camera of number of 100 times optical scorch?

Camera of number of 100 times optical scorch ends is a patent merely at present, have not make commercialized real product truly.

Patulous data

2013, beautiful can announce the patent of camera lens of a 100 times scorch, this patent should be to be aimed at 1/2.3 inch the long anxious type of sensor and design, focal length is 3.5-350mm, equivalent focal length is 20-200mm.

Ni Kang has had 83 the P900 of times scorch, beautiful can roll out 100 times scorch also is not what problem.

Beautiful can 100 times optical scorch is patent, aperture is F3.3-7.1

Although a inch of camera is popular now, but 1/2.3 inch still have certain vivosphere, some not quite the user that cares about a picture to pledge or the viatic watch for an opportunity that can seek big scorch to compare.

Beautiful can this patent predicts to be able to be commercialized very quickly, should meet on the long anxious watch for an opportunity that is used in next generation, may be SX70, let our wait and see what happens.

6, choose digital camera, how to choose digital scorch and optical scorch?

Optical scorch relies on structure of optical camera lens to realize scorch, scorch means and traditional camera design are same, depend on the focal length of camera lens, be through photographing the lens that resembles a head shift comes enlarge and the scenery that narrow need films. Optical scorch multiple is bigger, the scenery that can film is further. Optical scorch can support image principal part to become after resembling, resolution and picture won't be changed character, relatively clear. Digital scorch is the electronic enlarge of the picture actually, use original CCD on video inductor like element partially " interpolation " enlarge of algorithm general picture. Pass digital scorch, filmed scenery magnified, but the fall that its definition can have fixed rate, similar with the Zoom function in VCD or DVD, can reduce original image size only small, let image become bigger on LCD screen, but can not make details clearer, the biggest scorch of camera is not the product of digital scorch and optical scorch, it is addition. W290 is an average family expenses machine. Quality is good, want adjustable camera lens not to give a problem to be able to be used only very long.

7, is digital camera mixed without optical scorch be opposite automatically anxious?

This problem itself has bit of problem.

Actually any camera itself do not have optical scorch ability, the implementation of optical scorch is to depend on the scene that he mixes.

Because camera lens is not detachable,card machine says it has optical scorch is below (extortionary tear open bad) , it is an organic whole repeatedly, say such-and-such camera has how many times optical scorch so. Sheet is turned over aircraft is general camera lens is detachable change, even airframe and camera lens are bought apart, so sheet is turned over machine (point to airframe) do not have optical scorch.

8, do 100 multiple pile up optical scorch camera seniority?

1, Suo Ni RX10, 1 inch of sensor, cai department camera lens, equivalent 24-200 is anxious paragraph, constant 2, 8 aperture picture has character assure, defect is anxious paragraph not quite long;

2, the FZ1000 below the pine, 1 inch of sensor, lai blocks scene, equivalent 25-400 is anxious paragraph, the picture is qualitative very good, defect is long Jiao Duanguang those who encircle is a bit fast;

3, Fuji XS1, 2/3 inch sensor, fuji dragon camera lens, equivalent 24-624 is anxious paragraph, the picture has been compared character, the hand moves scorch quick, defect is foolish big black thick, weight volume is turned over like sheet;

9, mixture optics scorch and optical scorch distinction?

Distinction is as follows:

1, mixing optical scorch is optics of integrated mobile phone scorch, and digital scorch, and many camera lens cooperate with, the camera of algorithm of other picture qualitative aggrandizement is algorithmic, use at improving result of scorch of mobile phone camera. It is project of a systematization, actual performance suffers be confined to each camera algorithm, and hardware. For better sale, it is OK that works chamber of commerce pledges the picture pledges the picture better scorch multiple is packed to mix scorch multiple.

2, optical scorch is support picture of radial reflection nondestructive is qualitative, can pat the fine wisp of far as clearly as vicinity, this also is the technology that uses extensively in sheet to reach digital camera to go up instead. The position that adopts camera lens, object and focal tripartite produces change and optical scorch arises. Regard as when resembling a face moving in horizontal way, perspective and focal length can produce change, farther scenery becomes clearer, feeling letting a person resembles the feeling that the object goes forward one by one.

     Clearly, want to change a perspective to have two kinds of idea necessarily, one kind is the focus that changes camera lens. For the word that uses photography, this is optical scorch. Through changing scorch camera lens the relative position of medium each lens changes the focus of camera lens. Another kind is digital scorch. Digital scorch, it is the electronic enlarge of the picture actually, the one part that gets on original CCD video inductor is used like element " interpolation " method enlarge. the share on CCD video inductor video enlarge reachs whole picture. Pass digital scorch, filmed scenery magnified, but the character with inevitable meeting video loss. Actually digital scorch did not change the focus of camera lens, the point of view that just resembles face diagonal through be being changed will change a perspective, arose thereby " be equivalent to " the effect that camera lens focus changes.

10, what effect does the optical scorch of digital camera have?

The digital camera of optical scorch is in remote when scorch, the dimensional feeling of character or thing, administrative levels feeling wants those who compare digital scorch betterer, but the product of digital scorch is used is to should go to the lavatory a few.

The position that adopts camera lens, object and focal tripartite produces change and scorch of optical scorch optics arises.

Regard as when resembling a face moving in horizontal way, vision and focal length can produce change, farther scenery becomes clearer, feeling letting a person resembles the feeling that the object goes forward one by one.

Want to change a perspective to have two kinds of idea necessarily, one kind is the focus that changes camera lens. For the word that uses photography, this is optical scorch. Through changing scorch camera lens the relative position of medium each lens changes the focus of camera lens. So people sees, a few camera lens exceed long digital watch for an opportunity, in-house lens and sensitization implement mobile space is larger, scorch multiple is so bigger also.
