What are the classic models of digital cameras?

1. Canon A70: It has a 3x optical zoom lens and 3 million effective pixels, and has manual shooting modes such as M, A, S, etc., which is suitable for general family life shooting, and most photography enthusiasts also use it as a machine to practice;

2. Fujifilm S602: With 5 continuous shooting, dual card design, multi-** function, equipped with six times Fujinon lens and 1 to 10000 seconds high-speed shutter design, the shooting quality and function of Tuqi Zhen are better than other models of the same period;

3. Sony F717: It has a complete range of manual shooting functions and multi-point focusing and manual zoom ring design functions, and the camera's dark environment focusing ability, which is suitable for shooting at night

4. Nikon D70: With DX sleeve and relatively complete parameter design, the camera's continuous shooting ability and response speed are also better than those of the same model.

The imaging principle of the camera is:

The lens of a camera acts as a convex lens, and the light from an object passes through the lens of the camera and converges on the film to form an inverted, shrunken real image. Compared with traditional cameras, traditional cameras use "film" as the carrier of their recorded information space, while the "film" of digital cameras is its imaging sensor, and it is integrated with the camera, which is the heart of digital cameras. Digital cameras use photoreceptors to convert optical signals into electrical signals, which are then converted to analog and recorded on memory cards.

Like the eyes, there are all sorts of things in the traditional camera imaging process:

Through the lens, the scene is focused on the film.

The photosensitive agent on the film changes with the loss of the photofinch date.

The photosensitive agent that changes after receiving light on the film is developed and fixed by the developer.

Images that are opposite to the scenery or complementary in color Digital Camera Imaging Process:

1.The light is focused on the CCD or CMOS through the lens.

or CMOS converts light into electrical signals.

3.It is processed by the processor and recorded on the camera's memory.

4.Images are formed through computer processing and electro-optical conversion of monitors, or by printing by printers.

The specific process: The digital camera focuses the image on the CCD CMOS of the imaging element through the optical system, converts the photoelectric signal on each pixel into a digital signal through a D converter, and then processes it into a digital image through DSP and stores it in the storage medium. The light enters the camera from the lens, and the CCD performs color filtering and light sensitivity (photoelectric conversion), and "decomposes" the photographed object into pixels one by one according to a certain arrangement, and these pixels are transferred to the "analog-to-digital converter" in the form of an analog image and image dismantling signal, converted into a digital signal, transmitted to the image processor, processed into a real image, and then compressed and stored in a storage medium.

The reflected light of the scene is converging through the lens to form a latent image on the film, which is the result of a chemical reaction between the light and the emulsion on the film. The image is then developed and fixed. The digital image of the camera is different from the principle of film imaging, which is imaged on the CCD by the lens, and the photoelectric conversion of the CCD is used to generate the first signal, and then the image is generated after the electro-optical conversion of the display screen.

It is recommended that you buy the Canon ixus95, which is small and stylish, and focuses on quality and effect.

Now the national average price is 1580 yuan.

10 million effective pixels.

There is a face recognition function.

There is a camera function.

If you are below 880 yuan, you can buy Samsung PL50 L200 L1OO

For 1000 yuan, you can buy Fuji F60, which is the most cost-effective, and the effect is first-class.

About 1300 yuan, buy Canon SD1200 Panasonic FX500 beggars 2 machines to Panasonic ultra-low buy.

At present, the digital camera market is huge, from brands to cottages, from home entry to professional high-end, from a few hundred yuan to hundreds of thousands.

The reason why various cameras exist in the market naturally has its advantages and disadvantages.

Which model of camera is easy to use, you ask? This is too broad a question and it is recommended that you narrow it down:

**Range; scope of use; performance range;

Outside light range.

I saw this ** you posted, if you want to shoot sports photography and news, of course it's Canon's, and in comparison, Canon is faster than Nikon (in terms of operation and operation).
