佳能大CCD大光圈数码相机有哪些？英文双语对照

一、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。

二、光圈多大算大光圈？

通常来说，大光圈指的是f/2.8或更大的光圈。不过，这也与不同的相机、镜头和拍摄环境有关。在低光环境下，f/4或f/5.6也可以被认为是大光圈。

三、大光圈文案？

四、大光圈手机？

OPPOR9S就是采用的是难得的F1.7大光圈设计，这是国内最大的光圈。

光圈越大，进光量越多，夜拍更清晰，一般选购手机的时候要选择光圈比较大的手机，R9s还支持双核对焦功能，对焦快，照片不易糊。 OPPO R9s前置支持手势拍照和背景虚化功能：多人自拍从此变得很轻松，无需艰难的触碰拍照键，只需对准前置摄像头张开手掌，即可激活相机的2秒快门倒计时，顺利完成多人自拍；R9s还能将照片背景进行虚化，更突出人物主体，画面更加精美。

五、2.8的光圈大还是1.4的光圈大？

2.8的光圈大同1.4的光圈相比，2.8的光圈近距离更亮，但是穿透性没有1.4的强

六、摄影中数码相机的光圈怎么解释？

光圈是一个用来控制光线透过镜头，进入机身内感光面的光量的装置，它通常是在镜头内。表达光圈大小我们是用f值。 对于已经制造好的镜头，我们不可能随意改变镜头的直径，但是我们可以通过在镜头内部加入多边形或者圆形，并且面积可变的孔状光栅来达到控制镜头通光量，这个装置就叫做光圈。 完整的光圈值系列如下： f1.0，f1.4，f2.0，f2.8，f4.0，f5.6，f8.0，f11，f16，f22，f32，f44，f64。F后面的数值越小，光圈越大。光圈的作用在于决定镜头的进光量，光圈越大，进光量越多;反之，则越小。简单的说就是，在快门不变的情况下，光圈越大，进光量越多，画面比较亮;光圈越小，画面比较暗

七、大光圈和小光圈的区别？

一、本质不同

在相机上，大光圈是指把光圈调到数字小的位置，像是f/1.4、f/2.8、f/4等等，数字越小，光圈越大；而数字越大，光圈便越小，即是窗会变小，能吸入的光线不多。其实，数字和光圈大小是刚好相反的，摄影者定要留意这一点。

二、效果不同

1、使用小光圈的效果

小光圈(f/14)可以令太阳光芒更突出，而且保持前后景于景深范围内。如果用上小光圈，像f/11、f/16、f/22等，会造成以下的效果：

（1）减少光线进入，让摄影者可以放慢快门，捕捉时间；

（2）让光点变成散射状，即是光芒；

（3）景深变深，对焦主体以外的背景或前景不容易变模糊，可以保持清晰。

利用三脚架拍摄夜景时一般会用上f/8-11的小光圈，令景物保持于景深范围内，而这数值很多时候也是镜头成像的光圈。一般来说，在拍摄风景、有三脚架辅助的夜景、光芒，想保持前后景清晰，或是于阳光普照/ 光源 充足的情况下，摄影者可以用上小光圈。

2、使用大光圈的效果

用上大光圈，像f/1.4、f/1.8、f/2.8等等，会造成以下的效果：

（1）于同一快门时间下，大光圈可以让更多光线进入相机，从而令曝光增加，相片变亮；

（2）凝固时间：因为进入的光线增加，快门可以变更快，令飞快移动的物件可以“凝固”下来；

（3）景深变浅：这也许是大光圈其中一个很有用的用处，可以让对焦的主体从背景突显出来。

在拍摄人像、浅景深、或是于暗黑环境下手持拍摄，摄影者需要用上大光圈。

八、大光圈和小光圈的特点？

大光圈的特点：1. 具有明亮的景深，能够突出被摄物体并使其背景模糊。2. 具有良好的低光能力，能够在低光条件下拍摄清晰的照片。3. 适合拍摄人像、艺术照、夜景等。小光圈的特点：1. 具有更深的景深，能够清晰呈现整个画面。2. 具有更高的前后景分辨力，适合拍摄风景、建筑等。3. 可以用于长时间曝光拍摄，如星轨、流水等。

九、f1.8光圈算是大光圈还是小光圈？

大光圈。

数值越大光圈越小。反之亦然。

f/1.8光圈是一个变焦镜头的属性，意思是最大光圈F1.8-2.8。

光圈是一个用来控制光线透过镜头，进入机身内感光面的光量的装置，它通常是在镜头内。表达光圈大小我们是用f值。

对于已经制造好的镜头，我们不可能随意改变镜头的直径，但是我们可以通过在镜头内部加入多边形或者圆型，并且面积可变的孔状光栅来达到控制镜头通光量，这个装置就叫做光圈。

简单来说，我们把相机镜头前由多片金属叶片互叠组成的可变孔径的光栅叫做光圈。高端数码相机除了提供全自动（Auto）模式，通常还会有光圈优先（Aperture Priority）、快门优先（Shutter Priority）两种选项，让你在某些场合可以先决定某光圈值或某快门值，然后分别搭配适合的快门或光圈，以呈现画面不同的景深（锐利度）或效果。

十、什么是大光圈和小光圈？

大光圈和小光圈是指镜头的光圈大小。

在摄影中，光圈指的是镜头的光圈孔径大小，它决定了相机传感器上接收到的光线的数量。光圈的大小用“F数”来表示，F数越小，光圈越大，传入相机的光线也就越多；F数越大，光圈越小，传入相机的光线就越少。

大光圈通常指F数较小的镜头，这样的镜头能够传入更多的光线，因此在光线较暗的环境下，大光圈镜头能够更好地拍摄出明亮的照片。大光圈的另一个优点是能够产生浅景深的效果，即将主体与背景分离出来，突出主体。

小光圈通常指F数较大的镜头，这样的镜头透过的光线相对较少，因此能够得到更广阔的景深，即使前景和背景都能保持清晰，适合拍摄风景、建筑等场景。

在选择镜头时，大光圈和小光圈的选择需要根据实际拍摄需要和场景要求进行选择。

One, 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.

2, is aperture how old calculate big aperture?

Normally for, what big aperture points to is F/2.8 or bigger aperture. Nevertheless, this also is mixed with distinct watch for an opportunity, camera lens film the environment is concerned. Below low luminous environment, f/4 or F/5.6 also can be considered as big aperture.

3, table of big aperture article?

Big aperture, take instantaneous magic power.

In the light in waving, we record the good moment of the life with big aperture.

It is the blackart of photography, let each pieces of photograph be full of artistic lasting appeal.

Big aperture, make a picture brighter, clearer, have depth more.

It is the fountainhead of creativity, let your photography work extraordinary.

No matter be to film scenery, character still is still life, big aperture can bring outstanding result for you.

It is the edge tool that you record good memory, let each instant become unforgettable.

Big aperture, the brigade of the photography that lets you is more wonderful!

4, big aperture mobile phone?

What OPPOR9S uses namely is design of god-given F1.7 big aperture, this is country's biggest aperture.

Aperture is bigger, the capacity that receive light is more, night is patted clearer, mobile phone of general choose and buy when should choose aperture to compare old mobile phone, r9s still supports double check anxious function, right anxious fast, the photograph is papered not easily. The buy before OPPO R9s supports gesticulation to take a picture to change a function with setting empty: Much person is patted oneself become very relaxed from now on, need not hard lay a finger on takes a picture key, the buy before needing to aim only is photographed stretch the palm like the head, can activation the 2 seconds shutter of camera times, finish smoothly much person is patted oneself; R9s still can have photograph background empty is changed, main body of more prominent figure, the picture is more elegant.

5, is the aperture of 2.8 still the aperture of 1.4 greatly big?

The aperture photograph of 1.4 compares the aperture Great Harmony of 2.8, the aperture close quarters of 2.8 is brighter, but penetrability is done not have of 1.4 strong

6, how does the aperture of camera of the number in photography explain?

Aperture is one uses control light to pass through camera lens, enter the plant of the smooth quantity of sensitive face inside airframe, it is to be inside camera lens normally. Expressive aperture size we are to use F value. Good to been make shot, we change the diameter of camera lens impossibly at will, but we can be passed polygon is joined in camera lens interior or circle, and the aperture shape grating with alterable area comes achieve control camera lens know smooth amount, this device is called aperture. Complete aperture is worth series to be as follows: F1.0, f1.4, f2.0, f2.8, f4.0, f5.6, f8.0, f11, f16, f22, f32, f44, f64. The numerical value at the back of F is less, aperture is bigger. The action of aperture depends on deciding the capacity receiving light of camera lens, aperture is bigger, the quantity that receive light jumps over much; conversely, smaller. Say simply even if, in shutter changeless circumstance falls, aperture is bigger, the capacity that receive light is more, brighter; aperture jumps over the picture small, the picture is dismaller

7, big aperture and the distinction of small aperture?

One, differ constitutionally

On camera, big aperture is to point to an aperture to move the position with small number, resembling is F/1.4, F/2.8, F/4 is waited a moment, the number is smaller, aperture is bigger; And the number is larger, aperture is jumped over small, it is a window namely meeting decrescent, can inspiratory light is not much. Actually, number and aperture size are just contrary, the person that photograph wants surely advertent this.

Camera small aperture

2, the effect is distinct

1, the effect that uses small aperture

Small aperture (F/14) can make sun's rays awn more outstanding, and the background before maintaining within limits of depth of field. If use small aperture, wait like F/11, F/16, F/22, can cause the following effect:

(1) reduce the light to enter, the person that let photography is OK rein in shutter, take time;

(2) let spot turn scattering into shape, it is a ray namely;

(3) depth of field becomes deep, not allow to blur changeably to the setting beyond anxious main body or foreground, can keep clear.

Use tripod to film general meeting uses the small aperture of F/8-11 when night scene, your scenery maintains within limits of depth of field, and this numeric very much time also is camera lens into the aperture that resemble. Generally speaking, filming scenery, have tripod additional night scene, ray, the background before wanting to maintain is clear, or it is Yu Yangguang illuminate all things / below the condition with sufficient illuminant, the person that photograph can use small aperture.

Camera big aperture and the distinction of small aperture

2, the effect that uses big aperture

Use big aperture, wait a moment like F/1.4, F/1.8, F/2.8, can cause the following effect:

(1) fall at same shutter time, big aperture can let more light enter watch for a chance, make thereby exposure increases, photo brighten;

(2) caky time: Increase because of entered light, shutter can be changed fast, the thing that makes move rapidly is OK " caky " come down;

(3) depth of field becomes shallow: This perhaps is big aperture among them a very useful good, can allow pair of anxious principal part from setting dash forward show come.

Filming figure, shallow depth of field, or be film at be being held below dark black environment, the person that photograph needs to use big aperture.

8, big aperture and the characteristic of small aperture?

The characteristic of big aperture: 1. Have bright depth of field, can highlight the object that be photographed and make its setting ambiguous. 2. Have good small smooth capacity, can film below low smooth requirement clear picture. 3. Suit to film figure, art is illuminated, night scene. The characteristic of small aperture: 1. Have deeper depth of field, can clarity presents whole picture. 2. Have higher around scene resolution, comfortable in harmony photographs scenery, building to wait. 3. Can use at the time exposure to film, the course that be like a star, running water.

9, is F1.8 aperture big aperture or small aperture?

Big aperture.

Numeric bigger aperture is smaller. Vice versa.

F/1.8 aperture is the attribute of camera lens of a scorch, means is the biggest aperture F1.8-2.8.

Aperture is one uses control light to pass through camera lens, enter the plant of the smooth quantity of sensitive face inside airframe, it is to be inside camera lens normally. Expressive aperture size we are to use F value.

Good to been make shot, we change the diameter of camera lens impossibly at will, but we can be passed polygon is joined in camera lens interior round perhaps model, and the aperture shape grating with alterable area comes achieve control camera lens know smooth amount, this device is called aperture.

Simple for, we camera camera lens before by multichip the grating of the alterable aperture that metallic lamina each other folds composition is called aperture. High-end number camera besides offer full automatic (Auto) mode, still can have aperture normally preferential (Aperture Priority) , shutter is preferential (Shutter Priority) two kinds of option, let you can decide in certain circumstance some aperture is worth or some shutter is worth first, match respectively next suitable shutter or aperture, in order to present the depth of field with different picture (keen degree) or the effect.

10, what is big aperture and small aperture?

Big aperture and small aperture are the aperture size that points to camera lens.

In photography, what aperture points to is the aperture aperture size of camera lens, it decided to the amount of reception light is received on camera sensor. The size of aperture is used " F is counted " will express, f number is smaller, aperture is bigger, the light that passes into camera is more also; F number is larger, aperture is smaller, the light that passes into camera is less.

Big aperture shows F counts lesser camera lens normally, such camera lens can pass into more lights, because this is below the environment with darker light, big aperture camera lens can film better a bright picture. Another advantage of big aperture is the result that can produce shallow depth of field, be about to main body and setting depart come out, stress principal part.

Small aperture shows F counts bigger shot normally, the light that such camera lens passes through is opposite less, because this can get wider depth of field, although foreground and setting can keep clear, comfortable in harmony photographs the scenery, setting such as the building.

When choosing camera lens, big aperture and the choice need basis of small aperture film need and setting ask to undertake choosing actually.
