The difference between card machine and SLR

With the development of digital technology, digital products have been integrated into our lives. Card machine is an entry-level digital camera, which has the advantage of great portability, but the disadvantage is that the picture quality is average and the user's operability is not strong. SLR is a professional digital camera with good image quality and high user autonomy, but it is bulky. So what's the difference between a card machine and a SLR? Let's take a look at it next.

Basic introduction of card machine and SLR

There is no clear concept of card camera in the industry. Only those small shapes, relatively thin bodies and ultra-thin and fashionable designs are the main standards to measure this kind of digital cameras. The function of card machine is not powerful, but the most basic exposure compensation function is the standard configuration of ultra-thin digital camera, plus area or spot metering mode, which can sometimes complete some photography creation.

Single-lens reflex camera is a kind of camera that uses one lens and reflects the view through this lens. SLR cameras are professional and not suitable for any users. On the one hand, users must first have the necessary professional knowledge, and secondly, they must match different types of lenses to make good use of SLR digital cameras, which is likely to make the cost of lenses higher than the cost of buying digital cameras.

The first difference between card machine and SLR

1, volume and weight

The advantages of card machine are small size and light weight. It's basically not a burden to take a card machine when you go out. You can shoot while walking and put it in your pocket after shooting.

Machines with lenses are generally more than one kilogram. If you are away from home, a SLR, accessories and protective equipment are common. In addition, SLR is bulky and usually needs to be hung on the neck or shoulders, which is inconvenient to carry.

2. lens

The weakness of the card machine is the lens. One is that the aperture is too small, and the other is that the lens can't be replaced, which determines the weakness of the card machine, because the current lens technology really can't do everything. Portrait, macro, landscape, portrait, animals and plants, wildlife photography, microphotography and other different uses correspond to different types and specifications of lenses, and it is difficult to achieve a card machine to get higher-effect photos.

Because the whole imaging system of SLR (focusing and shooting) is a lens, the framing and imaging are consistent, and there is no visual difference. Single-lens reflex camera is composed of different photographic systems. For example, you can change wide-angle lens, lengthen lens, add color film and choose macro lens to meet your different needs. You won't miss the beautiful scenery because the camera lens is limited.

The second difference between card machine and SLR

1, shutter speed

Many photos taken by the card machine are pasted, not because the photographer has any problems, but because the strength of the card machine itself is not enough and the shutter speed is not fast enough. On the one hand, the lens aperture of the card machine is small, and less light enters, which leads to the need for normal exposure, so the shutter speed has to be lowered.

The lens aperture of a SLR is much larger. For example, the lens of portrait mirror 135mmF 1.8 has a diameter of 75mm when the aperture is fully opened, which can almost hold a card machine. In this way, in the case of poor light, the SLR can still maintain a high shutter speed, and the probability of photos being burnt is much smaller.

It is extremely important to keep the fastest shutter speed in the card machine at about11000 seconds, while the fastest shutter speed of the SLR digital camera can easily reach about110000 seconds, which makes the card machine far behind and is very suitable for shooting ecological environment.

Step 2 manipulate

A 3-inch screen is removed from the card machine, leaving little space and few buttons. When you are familiar with the operation, you can do a lot of things with your eyes closed, which is equivalent to what we usually call a fool camera, and the operation is simple.

The powerful control of the SLR is incomparable to the card machine. Because the single camera is large, there is enough space to put down many buttons besides a 3-inch LCD screen.

The third difference between card machine and SLR

1, price

Can't say that SLR is a money-burning thing. Because SLR cameras mostly use pure natural crystal or fluorite polished lenses, the price is much more expensive than ordinary glass and plastic lenses. Some even use ultrasonic motors to adjust the lens, which is less than mechanical vibration; Some have their own anti-shake patents (for example, Canon's EF series lenses have the IS logo), especially Canon's EF series lenses, the so-called' pure natural fluorite lenses with red lines', and an expensive lens is between 30,000 and 50,000.

The price of card machine is incomparable with that of SLR. You can buy a card machine of the same quality for more than 2000 yuan, but you can't buy a SLR.

2. Influence

The aperture and shutter style of the card machine are automatically generated by the machine, which is convenient for stupid users not to "paste" when they are not good at photography, but just like KFC and McDonald's always have three tricks to kill, they have no choice when they are tired of eating. Especially when you want to change the parameters such as aperture and shutter to do special effects, you can only do nothing, because beauty is the same woman. When you master certain shooting skills, the effect of shooting with SLR is endless.

I believe that after reading the difference between the card machine and the SLR, you must have a deeper understanding of the two. In the final analysis, card machines are generally used by ordinary consumers. Because these consumers may not be good at computer post-processing, the camera will make appropriate adjustments to the photos, such as color scale, contrast and color. Make it meet the needs of ordinary consumers, so it looks bright, clean and transparent. SLR is aimed at advanced users, so it needs a lot of post-processing to achieve the desired effect.
