What does full frame and non full frame mean for a DSLR camera? What s the difference? Hope for a de

One of the most important components of a digital camera is the image sensor (CCD or CMOS). Whereas, traditional optical cameras use film to sensitize light. If the image sensor size of a digital camera is the same as the 135 film size used in a conventional camera, it is full-frame; If it's smaller than 135 film, it's not full-frame.

What's the difference? To put it simply, the larger the CCD size, the higher the image quality. In fact, it is a question of photosensitive area.

35mm in conventional 35mm film refers to the width of the film, but in digital cameras, the closer the CCD CMOS diagonal size is to 35mm, the better the imaging effect. The average DC machine is much smaller than this size, while the digital SLR is closer. So if you are a lover of traditional cameras or are used to using digital SLR, you will feel that the DC camera shot can not be called **, at most it can be called a picture.

For example, Canno's 1DS DMark2 (Invincible Rabbit) has a COMS size of 35mm film, which is called full-frame.

However, I haven't used a full-frame DSLR yet, so I haven't realized how cool it is.

The image sensor is the same size as the 135 camera film.

Less than is not full.

The image quality and resolution of the full set are better than those of the non-full set.

The size of the sensor varies.

The full frame is 36*24mm, and the other formats are shown in the figure.

First, the specifications are different.

1. Full width: the sensitive area is 36 24 mm size.

2. Half width: half the size of 135 film, about 18x24mm.

Second, the vignetting is different.

1. Full frame: Vignetting may appear in full frame.

2. Half-frame: Half-frame is not prone to vignetting at a wide aperture.

Third, the effect is different.

1. Full-frame: The full-frame machine can provide better image quality performance at high ISO, and the full-frame performance is even better when shooting in low-light environments.

2. Half-width: Half-width machines can also have excellent light-sensitivity ability in general environments.

In the standard sense, the full set is the same size as the 135 film, which is 36mm 24mm, and the half pair (APS-C) is 24mm 18mm, and the actual CCD or COMS used by the camera is slightly smaller than the standard size. The imaging chip of the full camera has a larger photosensitive surface and better image quality; The same lens is used for a wider range of full-ride camera shots, and the depth of field bokeh effect is also better.

Remember to adopt it.

Both full-frame and half-frame refer to the area of the photoreceptor, with the full-frame photoreceptor area being as large as a traditional 135 negative, while the half-frame area is about 44% of the full-frame. The full-width photoreceptor (CCD COMS) has a large area, the cost is high, and of course it is expensive. We know that the image quality of ** mainly depends on the size of the area of the sensor, and the full-frame image quality is of course better.

In the figure below, you can clearly see the difference between the full frame and the half frame (where the APS-C size is half the frame, and the smallest area in the upper left corner is the sensor area of the card machine, and I think you should understand why the image quality of the card machine and the SLR machine is so different):

First, the subject is different.

1. Full frame: used to describe the image circle index of the lens and the size of the image sensor.

2. Half frame: It is a type of imaging specification that only uses half the size of the standard film format.

Second, the area is different.

1. Full width: the size of the area is 36 24 mm.

2. Half width: refers to half the size of 135 film, about 18x24mm.

Third, the characteristics are different.

1. Full frame: At the same equivalent focal length and aperture value, the smaller sensor size of full frame has better bokeh than the smaller sensor size.

2. Half-frame: The same amount of film can be doubled, for example, for 135 standard rolls, 36 shots can be used for normal shooting, and a total of 72 shots can be shot with a half-frame camera.

Full-frame (full-frame), half-frame (half-frame) refers to the different sizes of the camera's imaging components CMOS (or CCD), and cameras that use comms as large as the optical 135 camera film imaging size of 36 24mm are called full-frame cameras, identified as FX; Cameras with an aspect ratio of 3:2 ( are called half-frames, abbreviated as APS-C format, and identified as DX, Canon and Nikon APS-C format sizes are also different: Canon, Nikon.

Therefore, a full-frame 50mm lens has an equivalent focal length of 50 on a Canon DX camera, and a Nikon DX camera has an equivalent focal length of 50.

As for the performance of the two, the full-frame is superior to the half-frame high feeling, the color reproduction is good, the pixel is high, the imaging is ***, the background is good, and so on.

There is no half-frame concept, only APS-C format, and full-frame.

The full-frame is the same size sensor as the 135 film, and the APS-C format is generally about 24 16mm sensor, and the specifications of APS format cameras from different manufacturers are slightly different.

The difference between full-frame and half-frame SLR cameras, you can see the answer here.

The full-frame is for the size of traditional 35mm film. In the past, DSLR CCDs were smaller than 35mm film, and full-frame DSLR CCDs (or CMOS imaging elements) were the same size as 35mm film. The larger the CCD size, the higher the image quality.

The biggest difference between full-frame wheels and non-full-frame lenses is the effect on the focal length of the lens, the focal length number on the general lens is only applicable in the full-frame state, such as the Canon 24-70 lens is only really 24-70 on the full-frame camera, if it is installed in the APS-C format machine (such as Canon EOS70D), it is equivalent to, because Canon's image sensor is smaller, so the conversion factor to be multiplied is the equivalent focal length that is really applicable to non-full-frame cameras, The conversion factor for the aps format is: As a result, full-frame machines can easily "shoot wider" (because multiplied by the conversion factor makes the original wide-angle focal length less wide on non-full-frame machines); Instead of full-frame machines, it is easy to "shoot farther". If you're going to shoot a big scene, it's best to use full-frame, and if you're shooting birds or going to Africa to shoot lions, it's better to get a full-frame.

Of course, in addition to the difference in focal length, full-frame machines are generally professionally positioned, more high-end, good body materials, good processors, more high-tech means, higher pixels, and the effect of clapping without shaking in places where the black light is blind is better, etc., all in all, the full-frame is not only a small circle of the image sensor, but generally good things will give priority to equipping the full-frame body.

In terms of 'frame' alone, say the difference between a 'full' frame camera and a 'non-full' frame camera:

1. The adjacent black frame in the red frame indicates the area of the CCD of the full camera, and the longer side = 36mm.

2. The adjacent black frame in the blue frame represents the area of the CCD of the half-pair (APS-C) camera, and the longer side =.

3. In the vernacular, the bottom plate area of the full-frame camera is equal to that of 135 negatives.

Both full-frame and half-width refer to the size of the sensor in terms of area.

Generally, a sensor with a sensor area the size of a conventional 35 mm film is called full-frame. The natural half is only half of the whole width.

The larger the sensor area, the larger the area per pixel when the total number of pixels is the same. Similarly, the lighting conditions will generate more signal currents for the pixels. The higher the signal-to-noise ratio compared to the noise floor. Therefore, the full-frame camera should have a high image purity (low noise) in low light
