1. With the technological innovation and performance improvement of consumer-grade DC, high-end DC with 10 million pixels and superior performance emerges one after another. The entry-level SLR of Canon, Sony, Nikon, Pentax and other brands are constantly innovating, and the prices are also falling. The price of entry-level SLR and high-end DC has gradually leveled off, which has brought a lot of confusion to many friends who want to buy digital cameras at this price, and it is difficult to choose. From a technical point of view, the low-end SLR is superior to the high-end DC in terms of imaging quality, lens and reaction speed. However, high-end DC is attractive to buyers in terms of function, maneuverability and price. High-end DC or entry SLR? What kind of camera is suitable for me? Let's briefly analyze the advantages and disadvantages of high-end DC and entry-level SLR. Friends who wander between high-end DC and entry-level SLR may wish to choose according to their own needs.

Advantages and disadvantages of high-end DC

Advantages: As the flagship product of ordinary consumer digital cameras, high-end DC has powerful performance that ordinary consumer digital cameras can't match. Many functions of high-end DC can be compared with professional SLR. And many fuselage designs are getting closer and closer to SLR cameras. Most high-end DC's are made of metal, with fine workmanship. In addition, high-end DC mostly adopts high-quality lenses with large aperture, giving consideration to wide angle and telephoto, and the imaging quality has also been greatly improved. Simple and easy to use, with a variety of scene shooting modes and other functions. It is very convenient and flexible when shooting, which is convenient to leave more beautiful moments and can shoot videos.

Disadvantages: Although the performance of high-end DC exceeds that of ordinary consumer digital cameras, its price is also much higher. In terms of imaging quality, lens configuration and performance, there is a gap between high-end DC and entry-level SLR with the same price.

Advantages and disadvantages of entry-level SLR camera

Advantages: The original sensory area of the entry-level SLR is generally larger than that of the high-end DC, so the entry-level SLR will have better image quality while obtaining large-size images, which can bring clearer image quality. The manual function of the entry SLR is more powerful, and it has advantages with the continuous shooting function. And you can choose a large number of high-quality professional lenses.

Disadvantages: Compared with professional SLR, the entry SLR is a low-end product after all, and the general fuselage is made of plastic or synthetic materials, which can save costs and help to reduce the price of the fuselage. However, the price of the lens is still very expensive, and the later investment will increase. In addition, SLR cameras are slightly more complicated to use. And at present, all SLR cameras can't shoot short films.

3. First, the concept and classification of focal length

The focallength of a lens refers to the distance from the film plane to the optical center of the lens when the lens is focused at infinity (the optical center of the lens is not necessarily at the midpoint of the glass, but for convenience, we usually consider it this way).

A lens with a fixed focal length is called a main lens or a main lens. There are mainly three kinds of lenses: short focal length lens (also called wide-angle lens), standard lens and long focal length lens. A lens with multiple focal lengths is called a zoom lens. Wide-angle lens has a wider field of view than standard lens. A long focal length lens (the longest lens is called a telescope head) has a narrow field of view, and its magnification is high, so it can capture things that are quite small or far away from the scene frame. It must be remembered that the focal length not only affects the perspective, but also affects the width and tightness (multi-value) of the field of view.
