Is there an introduction to the SLR?Do you know anything about SLR?

SLR generally refers to single-lens reflex digital cameras, that is, digital digital, single, lens lens, reflex reflex English abbreviation DSLR. Representative models in the market are commonly found in Nikon, Canon, Pentax, Fujifilm, etc. In the early days, such cameras were generally larger and heavier.

It works by means that light passes through the lens to the mirror, is refracted to the upper focusing screen and forms an image, through which we can see the outside through the viewing window and the pentaprism. In contrast, a digital camera can only see the image through an LCD screen or an electronic viewfinder (EVF). Obviously, images that are seen directly are easier to shoot than images that are seen through processing.

When shooting in DSLR, when the shutter button is pressed, the mirror pops up, and the shutter curtain in front of the image sensor (CCD or CMOS) opens at the same time, and the light through the lens is projected onto the original sensor, and then the rear mirror immediately returns to its original state, and the image can be seen again in the viewing window. The structure of the single-lens reflex camera determines that it is shot completely through the lens focus, and the single-lens reflex digital camera can make the image seen in the viewing window and the film forever the same, and its framing range is basically the same as the actual shooting range, which is very conducive to intuitive framing and composition.

In addition, a great feature of SLR digital cameras is that they can exchange lenses of different specifications, which is the inherent advantage of SLR cameras, which is incomparable to ordinary digital cameras.

There is also the fact that the DSLR digital camera is now positioned in the high-end products of the digital camera, so in the area of the image sensor (CCD or CMOS) that relates to the photographic quality of the digital camera, the area of the SLR digital is much larger than that of the ordinary digital camera, which makes the photosensitive area of each pixel of the DSLR digital camera far greater than that of the ordinary digital camera, so that each pixel can also show a more detailed brightness and color range, so that the photographic quality of the SLR digital camera is significantly higher than that of the ordinary digital camera.

SLR refers to one of the tennis backhand techniques in sports, and the tennis backhand technology has a one-handed backhand (referred to as "SLR") and a two-handed backhand (referred to as "double-reflex") SLR is elegant and stable.

Buy a mirrorless camera, the "mirrorless" camera is positioned as a cross-border product between a DSLR camera and a card machine, and the most important feature of its structure is that there are no mirrors and prisms.

The history of the development of the class proves that no technology can be brilliant forever. In the era of film, film, the medium through which images were stored, had to be strictly protected from light leakage during framing. However, in the digital age, the situation has changed radically – CCDs are not afraid of light leaks.

It can be used for framing, but also can be used for imaging after clearing, so the necessity of the existence of the mirror has been greatly reduced, its working principle, determines that the mirror framing is not suitable for digital photography, in the digital camera that can be fully electronic, there is no need to keep a mechanical part - the mirror. Although people can tolerate the bulky and complex structure of the mirror because it can take into account the lens framing and protect the film from light leakage, the characteristics of the image sensor in today's digital age are not afraid of light leakage, so that the existence of the mirror has become unnecessary, and with the improvement of electronic framing technology, one day, the clarity and brightness of the electronic framing will sooner or later be good enough to replace the reflector. So, theoretically speaking, a single electric camera can have almost all the advantages of a DSLR camera - better image quality, greater depth of field, interchangeable lenses, waiting for the demand to explode, this kind of problem will definitely be solved, and the volume of the single electric is an advantage that the SLR can never catch up.

Before Sony launched the "mirrorless" camera, consumer electronics giants such as Olympus, Panasonic, and Samsung had launched mirrorless products that use an electronic viewfinder and can change lenses like a DSLR, and called them "single cameras". Hidehiko Teyogi, director of Sony's personal audio and video business department, said that "mirrorless" is a trademark specifically for the Chinese market, and its products are given two meanings: miniature and single-lens reflex cameras: the camera is miniature, small, portable, and can also change lenses like single-lens reflex cameras, and provide the same image quality as single-lens reflex cameras.

Little brother, you really don't understand SLR, 2000-3000 SLR is there, you can only buy the most inferior entry level, and you can only buy a dog head set machine.

I suggest that if you are not an enthusiast and the camera is used to record travel, you don't need to buy a DSLR at all, just play with your mobile phone, or buy a better card player, which will cost a lot of money. I don't know the basic knowledge of photography, the SLR can't be played, the dog head set is straight out**, don't do post-production, it's really not as good as the mobile phone.

If you are an audiophile, or want to become an audiophile, then your budget should be greatly increased, at least 8000+.

Two or three thousand can only buy a micro single, the set of SLR entry is also four or five thousand, and it is not a SLR that must be good-looking, no technology or bad shooting, the picture quality is good, the random lens is not good, it is very expensive to buy a lens by yourself, and it is troublesome to change the lens, if you use a lens to go around the world, the picture quality is not much different from the ordinary machine, and it is very cumbersome to bring a SLR when traveling, if there is a lens to change, it is even more cumbersome to bring a lens, in the end, I think it is still a small number, if you really want to buy a SLR, you can choose Nikon Canon, I think Nikon's colors are sharper and Canon's softer, and which one you like depends on your personal preferences.

The emergence of the camera has provided great convenience for human beings to record life, and so far, there are various types of cameras, and the functions are very powerful, and the SLR camera is now the choice of most people. So how to pick a DSLR camera?

1. Lens. The lens of the camera is often more important, and the zoom lens is less than 3x zoom ratio, and the prime lens is better. The most commonly used lens has a focal length between 28-105mm, which can basically meet the needs of daily shooting. It is better to choose those that can use additional mirrors or those with adapter rings.

Second, the fuselage. When choosing a camera, try to choose a metal material and seal it, so that it can be used in the rain and on the beach, preventing rain and sand, among which there are many cases of damage to digital cameras because of sand.

3. Image sensor.

Needless to say, the image sensor is also important, second only to the lens. As an image sensor, it is directly related to the imaging quality of the camera, and what we call "pixels" is the light-sensitive substance on the image sensor. Image sensors are divided into CCD and CMOS, and CMOS is widely used on SLR.

Fourth, the viewfinder.

Choose a camera with a rangefinder because it's bright, wide, and sharp. Many people tend to use the LED screen on the back of the camera to frame instead of using the viewfinder, which is unscientific. That's because the rangefinder will focus faster than your screen when capturing.

A good viewfinder comes with automatic parallax compensation, which compensates for the horizontal and vertical deviations between the viewfinder and the lens according to the corresponding distance setting, making up for the lack of a rangefinder.

5. Battery. The camera battery is extremely important, if you encounter a good picture, the camera has no power, which is unbearable for many people, so go out to shoot a spare set, wrapped with a protective compartment, to prevent power loss in winter.

There are really not too many choices at this price point, that is, it is the most entry-level, and the performance of no matter what brand at this price is almost not too entangled.

The full name of a DSLR camera is Single Lens Reflex (SLR). A DSLR can only be equipped with one lens at a time, so it is called a "single lens". The SLR has a reflector inside it, which reflects the recent light collected through the lens into the human eye, so it is called "reflector".

SLR cameras are divided into film and digital, so there are two types of film SLR (FSLR) and digital SLR (DSLR).

DSLRs are divided into full-frame SLRs (also known as 135 cameras) and non-full-frame (also known as APS SLRs) depending on the size of the sensor. Due to the decline of film, most of the best ones on the market are digital SLRs, and the following will explain to you the full-frame and non-full-frame DSLRs that are often heard.

1.Full frame.

The so-called full-frame is for the size of traditional 135 film. Conventional camera film is 35mm in size, 35mm is the width of the film (including the perforations), and 35mm film has a photosensitive area of 36 x 24mm. The size of a DSLR's CCD (or CMOS photosensitive imaging element) is the same size as that of a 135 film, 36 x 24mm, which is called "full-frame".

2.Partial Frame-APS

In 1996, the APS system, which was jointly developed by Fujifilm, Kodak, Canon, Minolta, and Nikon, began to be introduced. APS is the abbreviation of "Advance Photo System", which is translated as: "APS Advanced Photography System" in China.

The APS developers have made radical improvements to the original 135 spec, significantly reducing the film size and targeting the amateur consumer market.

In DSLR cameras, most of them use sensors smaller than 135 sizes, and almost all of them, except for Olympus' 4 3 system and full-frame, are about the same size as APS-C type film, so people call them "APS-C specifications".

SLR is now rarely used, because it is really inconvenient to carry it, although the previous era of poor mobile phone photography effect, SLR is popular in the world, that is a necessary equipment for photography enthusiasts, SLR ** The difference is huge, ordinary people buy a few thousand is enough, like bright colors you buy Canon, like natural and real you buy Nikon, anyway, I travel now with a mobile phone, do not pursue any quality, it is enough to record everything travel, professional photography, travel, want to save better, but it is good to use SLR, However, the top ten things that I regret buying the most, the first place in the evaluation of netizens is the SLR, you search for it on the Internet.

If you want to learn professional photography, it is recommended to buy a mid-range model, if you are just traveling, contact a mirrorless, light weight, optical zoom, and some entry-level operation settings, which are easier to control.

I haven't understood that a DSLR camera is a traditional film SLR camera, that is, a single-lens reflex camera. With the advent of the digital age, on the basis of the SLR, the imaging system was replaced by the traditional film with today's photosensitive originals, so today's DSLR camera, camera imaging principle, reflector, image sensor, focusing screen, optical viewfinder, pentaprism was born.

Lycra has some good ones at this price point, mine is.

The SLR at this price is estimated to be a little too inferior, but if you get started, buy a cheap one and be a little proficient in operation. When you get acquainted with it, buy a better one. Look for some books about photography, photography is a technical job.

SLR cameras are professional cameras, generally expensive is a good camera, if you want to buy a good quality and cheap you go to ask the sales staff of the store should be able to help you, to be honest, the average person really does not necessarily understand. Finally, I wish you to buy a real DSLR camera.

If you want to play, you have to buy a good one, so that you can play famously.

There is a compound bow higher than your good factory number.

It refers to a camera that uses a single lens, through which the light hits the mirror, and the light is viewed through the reflex. The so-called "single lens" means that the photographic light path and the framing light path share a lens.

SLR is a single-lens reflex camera, which means that the same lens is used for framing and shooting, and reflex means that the image is refracted through the mirror and seen by us.

You are given three options, research for yourself:

1: 600d 18-135 sets. More than 6 thousand. The mainstream entry-level SLR, the 18-135 lens has a wide focal length, acceptable imaging, and strong practicability. In terms of lenses, it is a one-step solution for many home users and beginners.

2: 650D 18-135 STM set, not on the market for the time being, soon, it is expected to be about 7,000, it is a 600D rising model, with STM lens has a strong advantage in photography. Same as above in terms of lens performance.

The performance of some of the fuselages is equal to or exceeds 60D, but the positioning is still an entry-level machine.

3:60D 18-135 set of machines, more than 8,000 town digging, C mid-range, with shoulder screen, more convenient when shooting. Better grip. It is more mainstream, and the lens performance is the same as that of the brigade.
