Does everyone use the Yuandao Jingwei camera when taking photos on site?

Everyone uses the Yuandao Jingwei camera for on-site watermark photography. Single Lens Reflex Camera (Single Lens Reflex Camera), also known as SLR camera, refers to a camera that uses a single lens, and the light shines on the reflector through this lens, and the view is taken through the reflection. The so-called "single lens" means that the photographic exposure light path and the viewing light path use one lens. It is not like a rangefinder camera or a twin-lens reflex camera that has an independent lens for the viewing light path. "Reflective" refers to a flat mirror inside the camera that separates the two light paths. The first SLR camera was developed in 1909. Since the 1970s, this technology has been widely used, and SLR cameras have become the new favorite of advanced photography enthusiasts and professional photographers.

DSLRs are not all high-end products

2006 was the year when the DSLR war broke out One year. During this year, the three major traditional home appliance manufacturers Sony, Samsung, and Panasonic collectively entered the DSLR market, and traditional manufacturers such as Olympus, Nikon, and Pentax also responded with their latest low-priced products. This has intensified product competition. On the other hand, it has also greatly enriched consumers' choices and further reduced the price of entry-level DSLRs to freezing point. Although high-end DSLR products often cost tens of thousands of yuan, there are many entry-level DSLR kits with lenses for less than 6,000 yuan and single bodies for less than 5,000 yuan. This price range is no longer considered a high-end product.

This price is close to the defense line of high-end consumer digital cameras. It can be said that since the price difference between DSLR and high-end consumer cameras is no longer obvious, it will directly shake the choice of some consumers who originally planned to purchase consumer cameras. Although DSLR is slightly larger than high-end consumer cameras, the control and image quality of DSLR have made a qualitative leap. Coupled with the ability to change different lenses as needed, these advantages make DSLR single-lens reflex cameras an absolute temptation. Although the image quality of consumer-grade cameras priced between 2,000 and 3,000 yuan, which are the most popular among consumers, is remarkable, they are not on the same level as DSLRs.

Problems

This necessary flipping action of the reflector also brings some other problems:

1. The moment of taking the photo, framing The device will be blocked.

Since the time of being blocked is only a split second, this is not a major problem for a reflector that resets immediately. However, some contingency issues arise. For example, when shooting with a strobe flash, you will not be able to see through the viewfinder whether the strobe device is firing normally.

2. Noise from reflector movement.

This may be an important issue in locations where quietness is required. Since there is no moving mirror in a rangefinder camera that suddenly blocks the light path, this noise does not occur.

3. Camera vibration is the overall movement of the camera caused by the flip-up action of the reflector.

Assuming you are shooting with a shutter speed of 1/500 second, then don’t worry. This vibration cannot be noticed. However, this vibration can be problematic when taking an accurate photo at a slower shutter speed, such as when shooting with a telephoto lens in low light.

In addition, using SLR to view the scene still exists
