What is a large format camera?

What is Quan Huafu? Medium format? Large format camera?

Quan Huafu-a term that appeared only after the appearance of digital cameras, especially digital SLR cameras, refers to the fact that the photosensitive element has the same frame size as the 135 film camera, which is 36× 24 mm

Medium format-it is a general term for cameras that used to be called 120.

120 camera has various frame sizes: 6× 4.5cm, 6× 6cm, 6× 7cm, 6× 8cm, 6× 9cm, 6×10cm and 6×12cm.

Large format-refers to a camera with a frame of 4×5 inches or more. There are 4×5 inches, 8× 10 inches and so on.

What is a large format camera?

At present, there are few large digital formats, which are basically film. Generally speaking, the imaging area is larger than 4X5 inches, which is called large format. A camera with this format is called a large format camera.

Smaller than the large format is the medium format, which is generally 4.5X6cm and 6X6cm. Less than medium format, Quan Huafu, 24X36mm. There are many smaller ones.

Large format, medium format, Quan Huafu, what's the difference between these cameras?

In Quan Huafu, the area of electronic film is equivalent to that of traditional film, and this framework is basically very popular in the consumer market. Nikon and Canon sell well in the full-frame camera market. Prices range from ten thousand to thirty thousand to forty thousand. Lycra also has several models from Quan Huafu, but the prices are above 40,000 to 50,000, so ordinary consumers will not buy them.

Medium format is a conspicuous product in the market, and its size is several times larger than that of Quan Huafu. The picture quality is also excellent, generally equipped on Hasselblad, Freescale and Leica cameras, and the price is extremely high, ranging from10-200,000.

Large format, only for special purposes, has not really been pushed to the commercial market, belonging to obsessed photographers, used for creation. The operation is complicated and there are many shots. Surgery is a technical job. The large-format camera weighs dozens or even hundreds of pounds, and it is very big, and there is a black box or something.

Are there any large-format digital cameras at present?

The so-called large format camera refers to a camera that uses a film size of 4×5 inches or more. There are also 5×7 inches, 8× 10 inches, 10× 12 inches, and even models that can shoot larger negatives.

Ccds used in large format digital cameras are all 14-bit or 16-bit ccds designed for high-end users. Even if the pixels of this CCD are the same as ordinary 8-bit CCD, its excellent dynamic range and color reproduction ability make it possible to obtain excellent pictures with the final actual shooting effect. Let's give an example:

Better Light's SUPER 10K-HS large format digital camera has a pixel value as high as 41600,000, a photosensitive element area of 72mm×96mm, a maximum resolution of 10200× 13600, a single photo file size of 794MB and a price of about 23,000 US dollars.

What are the brands and models of large format cameras? Please give me your advice. The more detailed, the better. Thank you. 10 point

Large format camera is also called setting machine, large setting machine, monorail setting machine, double-track setting machine, axis-shifting camera, external camera and so on. The remarkable feature of large format camera is that the photosensitive medium "film" it uses is sheet. At present, the mainstream plate sizes are: 8× 10 inch and 4×5 inch. In addition, the large-format camera also uses a lens with a fixed focal length, and its optical axis and focal plane can be adjusted freely within a certain range.

[Photography] What's the difference between large format Quan Huafu and medium format? 10 point

Is the size of the photosensitive element.

Arrange large format > medium format > Quan Huafu digital SLR by size.

Large format: such as Shana and Lin Hafu. The film size is 8x 10 inch, 4x5, etc. There are few numbers, and even if there are, they are used by observatories and satellites.

Medium format: A general term for cameras that used to be 120 film. Digital camera refers to the film whose photosensitive element is close to 120, such as Zeiss, Leica and Pentax.

Quan Huafu: refers to the size of the photosensitive element of a digital camera close to 135 film, such as Canon 1D3, 5d2, 5D3, Nikon D4, D800, D600 and D700. It is more common at present.

What brands of medium format cameras are there? What are medium format and large format commonly used for?

1, in fact, large format and medium format are the concepts of the film era, and Quan Huafu is the concept of digital SLR, not something of an era.

2. The most outstanding advantage of medium format is that it reaches a balance point in terms of larger imaging area and relatively light weight. It not only has larger imaging than 35 mm film, but also can accurately display larger photos, and it is much lighter than 4 * 5,8 *10, and the operation is relatively convenient and simple.

What's the difference between a medium format camera and a large format camera? What is the size of the so-called frame? ...

Nikon Canon doesn't do this because there is little market demand for these things, and the research and development expenses can't make ends meet, which is unnecessary. And becoming a monk halfway, naturally, you can't compete with old German brands, and no one wants to take the risk. Film is needed to represent very large formats. After all, in fact, the most expensive camera now is probably the digital photosensitive element. This thing has a high technical content. The bigger the more expensive, the bigger the more expensive. Look at Hasselblad and mamia. Even the cheapest Pentax 645D costs more than 70,000 yuan, and it is still rising. No matter what frame it is, it is called SLR, which essentially means "single lens reflex camera". Then look at its appearance. Is there only one shot? Is there a reflector in it? Then it's over. It's a SLR Medium format and large format are generally used for advertising films. Outdoor advertising, because outdoor advertising needs a large area of film, digital camera pixels are not enough. This kind of film needs more than 50 million pixels to make an advertisement outdoors, so it is in large format. What it is called and what 120 means are meaningless. I only know that 120 is twice as much as 135. Ask again if you don't understand. I teach photography.

What is large format, Quan Huafu, medium format, APS?

Quan Huafu's goal is the size of the traditional 35mm film. In the past, the size of digital SLR CCD was smaller than that of 35mm film, and the size of Quan Huafu digital SLR CCD (or CMOS photosensitive imaging element) was the same as that of 35mm film. The larger the CCD size, the higher the imaging quality.

Medium frame refers to the imaging size between a small frame of 36×24mm and a large frame of 4×5 inches. At present, the medium format film camera uses 120/220 film with a width of 6cm, and the imaging dimensions are 6X4.5cm, 6X6cm, 6X7cm and 6X9cm.

The size of a half frame is about 23.7× 15.6mm, or an APS-C frame.

The differences between "Quan Huafu" and "non-full-size" lenses are as follows:

When using a lens, the actual angle of view of the "non-full-width" lens can't reach the maximum angle of view of the lens, and the current equivalent focal length can only be converted by multiplying it by the "lens equivalent coefficient". For example, the imaging area of the photosensitive device S of Canon EOS 30D is 22.5mm× 15mm, and its "lens equivalent coefficient" is 1.6. The nominal focal length of the lens is multiplied by the focal length of 1.6, which is the equivalent viewing angle. For example, the focal length of the lens is 18mm, but EOS30D can't reach the lens angle of 18mm, and its angle of view is equivalent to that of a full-frame camera with a focal length of 28.8mm, which is 18mm× 1.6.
