世界最著名的三大数码相机镜头是什么？英文双语对照

一、世界最著名的三大数码相机镜头是什么？

1、卡尔蔡司镜头；　　卡尔蔡司镜头是来自德国的品牌，是目前为数不多的非日系厂商。卡尔·蔡司是一家历史相当悠久的光学仪器厂商，其出品的镜头在传统相机领域向来都是“高贵”的代名词，许多摄友以拥有卡尔·蔡司镜头为荣。　　

2、施奈德)镜头；　　作为德国知名的三大镜头制造公司之一，到现在已经有超过100年的历史，由于蔡司、徕卡的光环太耀眼的缘故，所以施奈德在外行人眼里变得默默无闻，在德国百年的光学传统工业里曾经出现过大量的优秀品牌，但在蔡司、徕卡的垄断下大多宣布退出，而施奈德靠着自己一流的设计还坚强的活着。　　

3、莱卡镜头；　　即leica。创立于1849年，由23岁的德国数学家卡尔．开尔纳(Carl Kellner)在威兹拉(Wetzlar)成立“光学协会”，开始镜头与显微镜的研发。目前是全世界最著名的镜头生产商之一。

二、数码相机大底？

相机搭载较大感光元件（俗称大底）。如果一款便携数码相机具备较大的感光元件和大光圈的话，无疑会具备较大的冲击力。此外，这些产品往往会搭配热靴接口，具备一定的拓展能力。有了这样的能力，不仅比较适合一般的摄影爱好者日常拍摄，还可以成为专业摄影师的备机。

　　较大感光元件尺寸会具备更好的高感光度性能、更好的画质表现。大光圈固定镜头的好处在于镜头可以尽量接近感光元件以获得更好的边缘成像，较大光圈结合光学防抖功能也令暗光拍摄不再成为难题。总的来说，大底大光圈便携相机为摄影爱好者提供了一个新的选择。

三、佳能大CCD大光圈数码相机有哪些？

1、佳能大光圈数码相机一个也没有；

2、所谓大光圈，包含两个含义，一是光圈最大孔径至少F2.8，二是成像弥散圆直径相当于全画幅传感器成像时F2.8的弥散圆直径。简单说，就是符合全画幅传感器使用F2.8及以上的镜头的成像标准时，才可以被称为大光圈；

3、数码相机的含义比较模糊，广义上数码成像的相机均可被称为数码相机，包含单反式、无反（微单）式、旁轴式、便携式等等，狭义上只是指不可换镜头的便携数码相机。一般情况下说的数码相机都按狭义理解，即指固定镜头的便携式相机；

4、在目前佳能固定镜头便携相机中，光圈最大的是F1.8（比如佳能G7X），虽然F1.8镜头的孔径查过全画幅今天头F2.8的孔径，其通光量符合大光圈的标准，但由于G7X是1英寸传感器，成像的弥散圆直径（虚化能力）相当于全画幅的F4.86，所以，G7X不符合大光圈的标准；

5、在目前佳能固定镜头便携相机中，传感器面积最大的的是半画幅（比如佳能G1XM3），但镜头光圈最大只有F2.8，镜头孔径虽然符合大光圈标准，但成像的弥散圆直径相当于全画幅的F4.48，也不符合大光圈的标准。

四、洛阳哪有大的数码相机卖场？

电脑城！

乘坐103到七里河下车！

有个世纪电脑城还有个赛博电脑城！

都是在哪里下车！分别在桥东头和桥西头！

八方电器里面卖的贵！要比电脑城里出手的柜上300-500之间！

店大欺人这是硬道理！电脑城便宜不是说是水货！你可以索要发票！电脑城里的买卖比较真实，想要行货水货根据自己和卖家的协商！不搞糊涂账！

五、数码相机十大品牌是哪些？

1 佳能Canon(1937年日本,领导品牌,市场占有率第一)2 尼康Nikon(十大数码相机品牌,1917年日本,领导品牌)3 索尼Sony(十大数码相机品牌,于1946年日本,世界品牌)4 三星Samsung(十大数码相机品牌,于1938年韩国)5 富士FUJIFILM(十大数码相机品牌,于1917年东京)6 松下Panasonic(十大数码相机品牌,于1918年日本)7 奥林巴斯OLYMPUS(十大数码相机品牌,于1919年日本)8 柯达Kodak(十大数码相机品牌,于1880年美国纽约)9 理光RICOH(十大数码相机品牌,于1936年日本东京)10 卡西欧CASIO(十大数码相机品牌,于1946年日本东京)

六、单反数码相机内存多少大够用了？

单反数码相机内都有RAW格式，建议内存大一点，目前主流是4G，200元左右，也不贵一般RAW格式是14M左右，有的单反还提供一次快门同时记录一张RAW和一张JPG的功能，占用的空间就更大了，20M左右，1G等于1024M，按自己的需求除一下看看具体要多大的卡吧！！！

七、数码相机为什么叫数码相机？

顾名思义，数码相机它摄影获得的成果是数字信息，它与胶卷相机区别在于，胶卷相机拍摄曝光是胶片涂层的化学反应，胶卷获影像(需冲洗)；而数码相机拍摄曝光过程是感光元件光电转换过程、获得的是数字信号信息存入内存卡里，数码相机最大好处是不需要使用胶卷这种耗材。

八、维修数码相机，怎样给数码相机放电？

镍镉电池需要放电后充电,否则容易有记忆效用.

镍氢电池虽然记忆效用比较轻,也最好采用用光充足的使用策略.一般在使用一段时间后,采用充分放电充分充电一次,来激活电池的最大容量.

锂电的记忆效用可以忽略不计,所以充电前不必放电.

有的针对镍镉电池专用的充电器,本身带放电功能,放完电后自动转为充电状态.

如果想用数码相机多用电来完成电池放电过程,对数码相机来说是无谓磨损,得不偿失,还是不使用这种方法为好.

建议把电池放到电动玩具或者用使用电池的各种电器里使用,最好是工作电流比较大的那些电器,那样放电时间可短些.

九、卡片数码相机？

照相机是记录静态图片的光学仪器，根据记录介质分为传统的胶片相机、拍立得相机（波拉片）和数码相机（记录为数字化图片文件）。

数码相机作为照相机的一大类，又根据镜头配置分为可更换镜头的和不可更换镜头的相机。

可更换镜头数码相机又分为可更换单镜头反光取景器数码相机（俗称数码单反）和可更换单镜头电子取景器数码相机（俗称单电，索尼将微型机身的单电称为微单，以便与其酷似单反外形但使用电子取景器的单电相机相区别）。

不可更换镜头数码相机又分为超薄数码相机即俗称的卡片机，还有一类拥有超大变焦比（30倍以上）镜头的大变焦数码相机，因为等效焦距可达到600-1200mm，又简称为长焦数码相机（其实其多数也拥有24mm的广角）。这类相机镜头硕大，其实不能称之为卡片机了，其外形酷似单反，又称为类单反相机。

数码单反

单电相机

卡片机

类单反相机

十、YASHICA数码相机？

《雅西卡》、日本二、三流的相机厂商，这个一台数码LOMO相机，随便玩玩。

有一个概念问题必须搞清楚：变焦和对焦是两回事，更没有自动变焦一说，只有自动对焦！！！

这是一台数码傻瓜机，没有变焦镜头，只是一个定焦镜头，更没有自动对焦系统，只有手动对焦 ，太傻瓜了，不值得买！

One, what is camera lens of the world's famousest camera of 3 large numbers?

1, camera lens of Ka Ercai department; Ka Ercai manages camera lens is the brand that comes from Germany, it is the manufacturer of the department that be not day with not at present much amount to. Cai Si of · blocking Er is the telescope manufacturer with a quite long history, the camera lens that its manufacture is in all along of traditional camera domain is " high " pronominal, a lot of photographing friend blocks Er · Cai to manage camera lens is flourish with having. 　　

2, Shinaide) camera lens; Regard Germany as one of production companies of well-known 3 big shot, had had history of more than 100 years to now, as a result of the cause with the too Cai Si, dazzling aureola that Lai blocks, so Shinaide becomes in outer pedestrian eye unknown to public, in Germany many outstanding brand once had appeared in the optical and traditional industry of hundred years, but announce to exit mostly below the forestall that gets stuck in Cai Si, Lai, and Shinaide is recumbent what oneself top-ranking design returns adamancy is living. 　　

3, Lai blocks scene; Namely Leica. Found 1849, block Er by German mathematician of 23 years old. Accept opening Er (Carl Kellner) is pulled in power at present (Wetzlar) holds water " optical association " , begin the research and development of camera lens and microscope. It is one of business of camera lens production with the famousest whole world at present.

2, digital camera large base?

Camera carries larger sensitive element (common weighs large base) . If camera of a portable number has larger sensitive element and big aperture, undoubted meeting has bigger wallop. In addition, these products often can match hot boots interface, it is certain to have extend capacity. Had such capacity, suit general photography lover to film daily quite not only, return the equipment machine that can make professional cameraman.

Dimension of larger sensitive element can have better high speed performance, better picture to be behaved character. The benefit that big aperture secures camera lens depends on camera lens can be close to sensitive component to be become in order to gain nicer edge as far as possible picture, optics of bigger aperture union is prevented shake a function to also make dark light films become difficult problem no longer. As a whole, big De Daguang encircled portable camera to offer a new alternative for photography lover.

3, does camera of number of big aperture of can big CCD have fine what?

1, camera of number of can big aperture also does not have beautiful;

2, alleged big aperture, include two implications, it is aperture the biggest aperture at least F2.8, 2 it is the dispersion round diameter that is equivalent to full frame sensor becoming the F2.8 when resembling into round like dispersion diameter. Say simply, of the camera lens that accords with full frame sensor to use F2.8 and above namely into when resembling a standard, just can be called big aperture;

3, the meaning of digital camera is more ambiguous, the number on broad sense all can be said into the camera that resemble amount to piles up camera, include sheet to return form, without instead (small sheet) type, by axial type, portable etc, the portable number camera that cannot change camera lens just points to on narrow sense. The digital watch for an opportunity that says usually understands by narrow sense, point to the portable camera of fixed camera lens namely;

4, in at present beautiful can secure camera lens in portable camera, aperture is the biggest is F1.8 (for instance beautiful can G7X) , although the aperture of F1.8 camera lens has checked full frame today the aperture of head F2.8, its connect smooth quantity to accord with the standard of big aperture, but because G7X is 1 inch of sensor, into the dispersion round diameter that resemble (empty influences ability) the F4.86 that is equivalent to full frame, so, g7X does not accord with the standard of big aperture;

5, in at present beautiful can secure camera lens in portable camera, sensor area is the largest is half picture (for instance beautiful can G1XM3) , but camera lens aperture has F2.8 only greatly most, although camera lens aperture accords with big aperture standard, but the F4.48 that is equivalent to full frame into the dispersion round diameter that resemble, also do not accord with the standard of big aperture.

4, which have Luoyang does great digital watch for an opportunity sell?

Computer city!

Take 103 get off to 7 lis of rivers!

A century computer city still has a city of the computer that surpass gain!

It is where to be to get off! Be in respectively the bridge east head and bridge on the west first!

What all directions sells inside electric equipment is expensive! Between the 300-500 on the ark that should compare the skill in computer city!

Person of inn big bully this is good sense! Computer city petty gain is not saying is commodities from abnormal channel! You can ask for bill! The business in computer city is realer, want him basis of travel goods commodities from abnormal channel to talk things over with what sell the home! Do not do muddleheaded Zhang!

5, digital camera what are 10 old brands?

1 beautiful can Canon(1937 year Japan, leader brand, the market is had rate the first) 2 Ni Kang Nikon(brand of camera of 10 large numbers, 1917 Japan, leader brand) 3 Suo Ni Sony(brand of camera of 10 large numbers, 1946 Japan, world brand) 4 SamSung Samsung(brand of camera of 10 large numbers, 1938 Korea) 5 Fuji FUJIFILM(brand of camera of 10 large numbers, 1917 Tokyo) the Panasonic(below 6 pines brand of camera of 10 large numbers, 1918 Japan) OLYMPUS(of 7 Ao Lin Ba Si brand of camera of 10 large numbers, 1919 Japan) 8 Kodak Kodak(brand of camera of 10 large numbers, 1880 American new York) 9 manage smooth RICOH(brand of camera of 10 large numbers, 1936 Japanese Tokyo) CASIO(of 10 calories of Western Europe brand of camera of 10 large numbers, 1946 Japanese Tokyo)

6, more or less does sheet turn over digital camera memory to be used quite greatly?

Sheet has RAW pattern inside digital camera instead, proposal memory is a bit older, at present the mainstream is 4G, 200 yuan or so, format of not expensive also general RAW is 14M left and right sides, some sheet still offer shutter to record a piece of RAW and a piece of function of JPG at the same time instead, the space that take up is larger, 20M left and right sides, 1G is equal to 1024M, the demand that presses oneself looks except specific want how old card! ! !

7, why does digital camera call a number camera?

Just as its name implies, the gain that its photography scores digital camera is digital information, it and film camera distinction depend on, film camera films exposure is the chemical reaction of film coating, film is obtained video (need to rinse) ; And digital camera films exposure process is transition of sensitive component photoelectricity, those who obtain is digital signal information stock memory Carrie, digital watch for an opportunity is the greatest advantage is not to need to use film material of this kind of bad news.

8, maintenance number camera, how to give digital camera discharge?

After need discharges, nickel cadmium cell charges, have memorial effectiveness easily otherwise.

Although nickel hydrogen batteries remembers effectiveness lighter, also had better use the use strategy with enough consumed. After using period of time commonly, use sufficient discharge to charge adequately, will activation of batteries most high capacity.

The memorial effectiveness of lithium report is negligible not plan, before charging so, need not discharge.

Some is aimed at charger of appropriative of nickel cadmium cell, itself takes discharge function, put electric hind to turn automatically to charge condition.

If want to use digital watch for an opportunity multi-purpose report will complete batteries discharge process, it is meaningless to digital camera wear away, the loss outweights the gain, still do not use this kind of method had better.

Suggest to be used in all sorts of electric equipment that put batteries to dynamoelectric toy to perhaps use use cell, had better be those electric equipment with working older electric current, discharge in that way time but some shorter.

9, card number camera?

Camera is the telescope that records static picture, the film camera that is a tradition according to recording medium to divide, pat stand camera (Paula piece) with digital camera (the record is digitlization picture file) .

Digital camera serves as a kind big of camera, it is according to cent of camera lens configuration again can change of camera lens and cannot change the camera of camera lens.

Can change camera of camera lens number is divided again to can change camera of number of single shot reflex viewfinder (common says digital sheet is turned over) and can change camera of number of viewfinder of single shot electron (common weighs only report, the only report of airframe of miniature of Suo Ni general calls small sheet, so that be exactly like sheet with its,return an external form but the photograph of only report camera of use electron viewfinder is distinguished) .

Cannot change camera of camera lens number is divided again for ultrathin number camera namely the card chance that common weighs, still one kind is had exceed big scorch to compare (30 times above) the camera of big scorch number of camera lens, because equivalent focal length can achieve 600-1200mm, abbreviation is camera of long anxious number (the wide part that actually its majority also owns 24mm) . Camera lens of this kind of camera is huge, cannot say actually be card machine, its appearance is exactly like sheet to turn over, call kind of sheet to turn over camera again.

Digital sheet is turned over

Only report camera

Card machine

Kind sheet turns over camera

10, YASHICA number camera?

" Yaxika " , Japan 2, small-time camera manufacturer, camera of LOMO of this a number, play casually.

Problem of a concept must make clear Hunan: Scorch and right anxious it is two different matters, do not have automatic scorch to say more, be opposite automatically only anxious! ! !

This is a number goofy machine, without scorch camera lens, it is one focuses camera lens only, do not have more be opposite automatically anxious system, only the hand is moved right anxious, too goofy, undeserved buy!
