Invite photography experts to answer: knowledge about SLR cameras. I want to read a post and become an expert! I know nothing about SLR!

1, the full name of SLR is "(digital) single-lens reflex camera", which is DSLR (digital single-lens reflex). Its essential element is: 1, which must be a single lens; 2. There must be a reflector.

There are many differences between SLR and card. Card machine is actually a very general concept, and all small and light cameras can be called card machines. The SLR can't be made very thin because of the reflector, so it won't be a card machine. In general, SLR has the following characteristics compared with ordinary cards on the market: 1, interchangeable lens; 2, the size of the photoreceptor is large, and the imaging effect is good; 3. Allow more complicated and professional operations. 4. Large volume and heavy weight. However, these characteristics are not absolute. For example, Sigma DP 1S card machine has the same size as SLR, and the imaging effect is comparable to SLR.

It should be pointed out that in addition to SLR and card, there are many other types of cameras, such as large-size full-function manual DC, single-electricity, paraxial system and so on.

The question 3, 4, 5, 6, 7 is too speechless to answer for the time being.

8. With a budget of 5,000 yuan, if you want to buy a SLR with a lens, you can only buy the lowest end. Canon 500D+ 18~55 sets, or Nikon D5000+ 18~55 sets. A slightly better lens is only three or four thousand yuan, and the total budget of 5,000 yuan is still a little worse.

9. I think what you don't realize is that before you ask questions, you should at least know something about yourself, and don't ask questions that make others speechless. . . Anyway, the later I answer, the more speechless I am, and the third question really can't be answered. Your question covers almost everything a photographer needs to know in half a month. What I can give you is either a few simple sentences or a long paste on the Internet.

Although your score is not low, experts with real kung fu don't necessarily care about your score of 100. .
