Why is the photo taken by SLR blurred on the mobile phone, but the bigger it is, the clearer it is?
SLR cameras (SLR cameras) are also called SLR cameras. Refers to a camera that uses a single lens, through which light shines on the reflector and takes a view through reflection.
The so-called "single lens" means that the photographic exposure light path and the framing light path share a lens, unlike the paraxial camera or the double-reflex camera, the framing light path has an independent lens.
"Reflection" means that a plane mirror in the camera separates the two light paths: the mirror falls when taking a view, reflecting the light of the lens to the pentaprism, and then to the viewing window; When shooting, lift the reflector quickly, and the light can shine on the film or photosensitive element CMOS or CCD.
2006 was the year when the DSLR war broke out in an all-round way. In this year, Sony, Samsung and Panasonic, three traditional home appliance manufacturers, collectively entered the DSLR market.
Traditional manufacturers such as Olympus, Nikon and Pentax have also come up with their latest low-priced products to deal with it. On the one hand, they intensify product competition, on the other hand, they greatly enrich consumers' choices and further reduce the price of entry-level DSLR to freezing point.
Although there are tens of thousands of high-end DSLR products, entry-level DSLR packages with lenses below 6000 yuan and single bodies below 5000 yuan abound, and this price is no longer a high-end product.
This price has almost reached the defense line of high-end consumer digital cameras. It can be said that the price difference between DSLR and high-end consumer cameras is not obvious, which will directly shake the choice of some consumers who originally planned to buy consumer cameras. Although DSLR is slightly larger than high-end consumer cameras, the control and imaging quality of DSLR have made a qualitative leap.
In addition, different lenses can be replaced as needed, which constitutes the absolute temptation of DSLR single-lens reflex camera. Consumer-grade cameras with the most choices of 2000 ~ 3000 yuan, although the imaging quality is also remarkable, are not comparable to DSLR at all.
