With the development of digital technology, digital products have been integrated into our lives. Card cameras are entry-level digital cameras. Their advantages are great portability, but their disadvantages are average image quality and poor user operability. SLRs are professional-grade digital cameras with good image quality and high user autonomy, but are larger in size. So what are the differences between card cameras and SLRs? Let us find out together.
Basic introduction to card cameras and SLRs
There is no clear concept of card cameras in the industry. They only refer to those with compact appearance, relatively light body and ultra-thin and stylish design. It is the main standard for measuring this type of digital cameras. The function of the card machine is not powerful, but the most basic exposure compensation function is also the standard configuration of ultra-thin digital cameras, coupled with the area or spot metering mode, sometimes it can complete some photographic creations.
SLR camera, also known as single-lens reflex camera, is a camera that uses one lens and reflects the view through this lens. SLR cameras have a certain degree of professionalism and are not suitable for all users. First of all, it is necessary for users to have the necessary professional knowledge. Secondly, to make good use of SLR digital cameras, they must be equipped with different types of lenses. This is likely to make the lens cost more than buying a digital camera. The cost of the camera.
The difference between a card camera and a SLR 1
1. Size and weight
The card camera is better in its small size and light weight. You can carry one when you go out Card cameras are basically not a burden, and you can take pictures on the go, and put them in your pocket after taking pictures.
A SLR machine together with the lens generally weighs more than one kilogram. If you travel far away, it is very common for a SLR, accessories, and protective equipment to weigh two or three kilograms; in addition, the size of a SLR It is very large and usually needs to be hung around the neck or shoulder, making it inconvenient to carry.
2. Lens
The weakness of the card machine is the lens. First, the diameter is too small, and second, the lens cannot be replaced. This determines the weakness of the card machine because of the current lens technology. There is really no one lens that can do everything. It can be used for different purposes such as portraits, macro, landscapes, portraits, animals and plants, wildlife photography, microscopic photography, etc. Each lens corresponds to different models and specifications of the lens, so if you want to get higher As for the photos with the effect, it is very difficult to achieve with a card machine.
Since the entire imaging system (focusing and shooting) of an SLR is one lens, the framing and imaging are consistent, and there is no visual difference. SLR cameras use interchangeable lenses to form different photography systems. For example, you can change the wide-angle lens, lengthen the lens, add color film, and choose a macro lens, etc. to meet your different needs. You won't miss the beautiful scenery because of the limited camera lens.
The difference between card cameras and SLRs 2
1. Shutter speed
Many photos taken by card cameras are blurry, and there is no problem with the photographer. , but the card machine itself is not powerful enough and the shutter speed is not fast enough. On the one hand, the lens of the card camera has a small clear aperture, and less light enters the camera. As a result, the shutter speed has to be slowed down if normal exposure is required.
The lens diameter of SLR lenses is much larger. For example, the portrait lens 135mmF1.8 lens has a diameter of 75mm when the aperture is fully opened, which can almost fit a card camera. In this way, when the light is not good, the SLR can still maintain a very high shutter speed, and the probability of the photo being blurred is much smaller.
The fastest shutter speed in a card camera is extremely important, which is maintained at about 1/1000 seconds, while the fastest shutter speed of a SLR digital camera can easily reach about 1/10000 seconds. Such a fast shutter speed makes the card It is beyond the reach of a camera and is very suitable for photographing the ecological environment.
2. Control
Except for the 3-inch screen, the remaining space of the card machine is very small, and there are very few buttons. After you are familiar with the operation, many things are closed. It can be done with your eyes, which is equivalent to what we usually call a point-and-shoot camera, and it is easy to operate.
The powerful control of a SLR is unmatched by card machines. The reason is that the size of the single-shot camera is large, so in addition to a 3-inch LCD screen, there is enough space to put a large number of buttons.
The three differences between card cameras and SLRs
1. Price
It must be said that SLRs are expensive things, because SLRs mostly use pure natural crystals Or fluorite polished lenses, so the price is much more expensive than ordinary glass and plastic lenses. Some even use ultrasonic motors to adjust the lenses, which have less vibration than mechanical ones; some have their own anti-shake patents (such as Canon's EF series lenses with the IS logo), especially Canon's EF series lenses with red lines. It's the so-called 'pure natural fluorite lens. An expensive lens costs between 30,000 and 50,000 yuan.
The price of a card machine is incomparable to that of a SLR. You can buy a card machine of comparable quality for more than 2,000 yuan, but if you want to buy a SLR, there is still a big gap.
2. Effect
The aperture and shutter style of the card machine are automatically generated by the machine. It is convenient for fool users who are not good at photography to avoid "mush", but it is like KFC and McDonald's always have the same three deadly tricks. When you are tired of eating, there is no choice. Especially when you want to change parameters such as aperture and shutter speed for special effects, you have no choice but to take pictures of beautiful women and Eastern women. Once you master certain shooting skills, the effects of shooting with a SLR are endless.
I believe that after reading the above differences between card machines and SLRs, you must have a deeper understanding of the two. In the final analysis, card machines are generally used by ordinary consumers. Because these consumers You may not be very good at computer post-processing, so the camera will make appropriate adjustments to the photos, such as levels, contrast, and color. Make it meet the needs of ordinary consumers, so it will look bright, clean and transparent. DSLRs are for advanced users, so a lot of post-processing is required to achieve the desired effect.
