What is the difference between full frame and medium format in photography, and what is the differen

First of all, it is necessary to understand the meaning of the frame, which is a concept introduced from the era of film cameras, the format refers to the size of the film, the original 135 camera film size is 24x36mm, so the reference to the digital age, the image sensor (CCD or CMOS) is equivalent to this size, called full frame. The larger the sensor, the better the image quality.

Digital cameras can be divided into medium format, SLR, single electric (Sony called micro mirrorless), rangefinder, SLR, card, etc.

1.Medium format cameras, high-end professional cameras, image sensor size is larger than full-frame. This kind of is used professionally, and it is expensive. Representative brands include Hasselblad, Phase One, Pantex and so on. The Pantex 645D sensor size is 44x33mm.

2.Single-lens reflex SLR camera, commonly known as SLR. It can be divided into full-frame, the image sensor is about 24x36mm, this kind of professional machine, representative brands are Canon, Nikon, Sony; aps-h, the image sensor is.

This kind of machine also belongs to professional machines, and the representative brand has Canon, which is not used by other manufacturers; APS-C, the image sensor is left and right. This kind of machine is divided into quasi-professional machine and entry-level machine, and the representative brands are Canon, Nikon, Sony, etc.; 4 3, the image sensor is. Representative brands are Olympus and Panasonic.

3.Single-camera is called mirrorless camera by Sony. It is a camera with an interchangeable lens that has a mirrorless system or a fixed mirror system.

The format is in APS-C format, and the representative brand is Sony. The format has 4 3 formats, representing brands such as Olympus and Panasonic; At present, the two giants of Canon and Nikon have not yet produced such machines. This type can be used as a standby for professional aircraft.

4.Rangefinder cameras, cameras with optical viewfinder systems, there is a certain parallax between what the viewfinder sees and what is actually taken, and the picture quality is good. The image sensor is about 1 inch, 8x6mm.

There are also smaller ones. A better one can be used as a standby for a professional machine. Most manufacturers have products, and from this type of onwards, they can all be classified as consumer cameras.

5.Similar to a single-lens reflex camera, the appearance is more like a single-lens reflex, mirrorless system, there is an electronic viewfinder, the handling is similar to a single-lens reflex, but the lens cannot be replaced, the image sensor is 1 inch and below, the general focal length is relatively long, and the largest one is currently 36x zoom. Representative brands include Fuji and so on.

6.Card machine, the largest sales in consumer machines, image sensor 1 inch and below, most of them are below 1 2, basically there is no manual function, but in order to suit beginners, they are set up with scene mode, face recognition, smiley mode, etc., to improve the success rate of shooting.

To put it simply, the full-frame is to see things with the human eye at night, and the medium format is to see things with the cat's eye at night, understand?

1. Different sizes:The size of the full-frame is larger than the size of the half-frame. The full-frame size is twice the size of the half-frame.

Full-frame, also known as full-frame, refers to the size of the photosensitive area of 36 24 mm. The so-called half-frame refers to the size of the photosensitive area of 18 to 24 mm. And Fan Chai.

The specifications here are mainly used to describe the image circle index of the lens and the size of the sensor. That is, the sensor of the same size, half of the width is half of the full width, and half of the width is also called half of the frame, and the common one is 135 film with a size of 18 24mm.

Comparatively speaking, the larger the size of the sensor, the better the image quality, and the more refined the picture when taking pictures with a full-frame camera. However, due to the large size of the sensor, the body and weight of the camera are larger than those of a half-frame.

2. The picture quality is differentFull-frame provides better image quality at high ISO, with larger frames for imaging that can achieve a shallower depth of field and accurately reflect the true focal length of the lens, while half-frame is not sensitive to light capture, and the wide-angle is relatively small, and the half-frame camera sees a cropped version of the image.

3. The cost is differentThe full-frame system is more expensive, and it has a larger format in terms of imaging, so it can obtain a shallower depth of field, and the same lens is mounted on a half-frame camera, and the wide angle is relatively small. The difference between full-frame and half-frame is also the realism of the image, with a full-frame camera giving you an image that accurately reflects the true focal length of the lens, while using a half-frame camera, you see a cropped version of the image.

The origins of large-, medium-, and full-frame cameras are in the film era.

1. Common film SLR cameras generally use 135 film, and the imaging size is about 36x24mm. In the digital age, digital cameras with 36x24mm sensors are called "full-frame" cameras.

2. Medium format film cameras generally use 120 film, and the imaging size is usually inches, 6x6 inches or 6x9 inches. In the digital age, digital cameras larger than full-frame sensors are called "medium format" cameras. For example, Pentax and Fujifilm's medium format products have an image size of 33x44mm, which is slightly smaller than the medium format cameras of the film era.

3. Large-format film cameras are professional cameras, generally using dry-plate film, and the imaging size can reach 8x10 inches. If you take a shot, you need to change the film box. For example, the famous Lin Haofu (or Lin Haf) camera. In the digital age, there are no "large-format" civilian cameras.

Linhof cameras.

Full-frame, the area of electronic negatives is equivalent to the area of traditional film, and this format is basically more popular in the consumer market, and the full-frame cameras of Nikon and Canon are selling well in the market. **10,000 to 30,000 or 40,000, Lycra also has several full-frame models, but ** above 40,000 or 50,000, ordinary consumers will not buy it.

Medium format is a fairly visible product on the market, and the format is several times larger than the full frame. The picture quality is also super good, generally in Hasselblad, Phase One, Leica cameras are configured, ** is also very high, ranging from 100,000 to 200,000.

Large-format, only for special purposes, has not really been promoted to the commercial market, belongs to obsessive photography enthusiasts, for creative use. The operation is very complicated, there are many lenses, and the operation is a technical job. A large-format camera weighs dozens or even hundreds of pounds, is very large, and has a camera obscura.

The full-frame is actually a small format, and the MOS standard size is the original 135 film size, with a size of 36x24mm; There is no standard size for medium format, generally between full-frame and old 120 film, the common size is 44x33mm, some manufacturers also have other sizes, but the difference is not large; Large format is not used in the civilian field, but is generally used in the military, scientific research, space detectors and other fields.

This is a classification of the film era, with large-format cameras using loose sheet film, medium-format cameras using 120 film, and full-frame cameras using 135 film.
