What’s the difference between micro and SLR?

Structure and property comparison
1. difference in metering mode
TTL optical system is in SLR, five prism positions with a special metering sensor, calculate the camera sensor by light, so that the user can take number metering system as a reference, the parameters of the manual adjustment of exposure. So the optical viewfinder digital SLR camera (or shoulder screen and the main display), the image below is a total exposure of the reference reading, the reading according to the real-time change of different brightness into the lens image, love the experience of manual control camera fun users is to meter for setting up the reference to determine the exposure needed to ensure that. Not overexposed or underexposed.
For micro and conventional portable digital cameras, the metering process does not become a separate system, nor is there a complex metering sensor like slr. The metering process is completely completed by the main camera sensor and image processor, no reflector structure, direct exposure to light to a photosensitive element, a photosensitive element converts light signal to output real-time image signal to the screen and the image processor, the image signal is analyzed by the image processor, and finally get the correct exposure set.
2. autofocus system differences
The SLR uses a phase difference focusing system that is independent of framing, imaging, and photometry. Phase difference focuses the focus of the picture by way of distance measurement. The components that complete the ranging process are called AF sensors (AutoFocus, autofocus). After the SLR camera reflector and a side reflector (or sub mirror), the vice reflector will take part of the light incident on the AF sensor, to determine the focus by location, mobile by complete automatic focusing lens control system.
Micro single use contrast focus, this focus is not micro, alone, most portable digital cameras and cell phones, including iPhone, are using this autofocus method. Like a micro metering system, the micro focus system is not a separate system. The contrast focus is still conducted through the camera’s main photoreceptor and the image processor.
3. lens
Micro single with SLR can assemble single micro lens lens, but choose a larger space, compatibility than the SLR, powerful micro single lens is the flange from smaller, can make a lot of old footage of rebirth, as long as a ring on the line.
And many of the SLR Lens bayonet, different brand bayonet is incompatible, yes, more monopoly development. Of course, SLR lenses are far more expensive than micro SLR cameras.

What is a micro camera?

Micro single contains two meanings: Micro micro, small, single, replaceable type single lens camera, that is to say the word is expressed with small volume and general quality of the SLR camera, which is small and micro SLR cameras have called micro camera.
Ordinary card digital cameras are fashionable, but they are always too beautiful to be captured by aperture and lens size, while professional SLR cameras are too bulky. So, from both the long and micro camera came into being. Micro cameras range between card digital cameras and SLR cameras, just as netbooks appear between laptops and smartphones.

What is a SLR camera?

The full name of SLR is “camera” (Single Lens Reflex Camera, abbreviated as SLR), also known as SLR cameras, and SLR cameras are called “monocular cameras” in Hong Kong and Hong kong. It is a camera with a lens and viewfinder through this lens. The “single lens” refers to photography, exposure, light path and viewfinder light sharing a lens, unlike the side axis camera or double reverse camera, viewfinder, light path has independent lens. The “reflection” refers to the camera in a plane mirror two separate optical viewfinder viewfinder: fall, the lens light into five prism, then to the viewfinder; when shooting the mirror fast up, light can be irradiated to the photosensitive element CMOS.
SLR is not a product of the digital age. There has been a SLR camera as early as the age of film. As the photo carrier to digital SLR with us into the digital age, now we say the SLR is usually said digital SLR camera.
The internal structure of the SLR, a mirror and a five prism light reflection, the mirror for external light reflection by physical way to the viewfinder and the five prism (or five mirror) has become the main component of SLR camera viewfinder, on the one hand, the most remarkable is single and micro SLR the difference in.
In the form of specular reflection, the human eye is finally able to observe the object in the camera’s viewfinder. This viewfinder is called an optical viewfinder. Whether you have an optical viewfinder is also considered the biggest difference between SLR and other consumer portable digital cameras.

Main features of SLR camera:

1, SLR digital camera is a big feature is that you can exchange different specifications of the lens, which is a natural advantage of SLR cameras, ordinary digital cameras can not be compared.
Now, 2 high-end SLR digital cameras are positioned in the digital camera, the digital camera photography in the photosensitive element relationship quality (CCD or CMOS) area, the area is far greater than the ordinary digital SLR digital camera, which makes the sensitive area of each pixel point of the digital SLR camera is far greater than the ordinary digital camera. Therefore can also point to each pixel showed more detailed brightness and color range, the digital SLR camera photographic quality was significantly higher than that of ordinary digital camera.

The working principle of SLR camera:

In the system of digital SLR cameras, light through the lens reach the mirror, reflected in the above on the screen and the images formed through the eyepiece and the five prism, we can see the scene outside the viewing window. By contrast, the average digital camera can only see images taken through the LCD screen or the electronic viewfinder (EVF). Obviously, the direct image is better than the image you see.
The shooting in DSLR, when you press the shutter button, the mirror will go up, the photosensitive element (CCD or CMOS) in front of the shutter curtain will open at the same time, it is projected to the original photosensitive photosensitive light through the lens, and then after the mirror immediately restore the viewing window in the image can be seen again. The structure of single lens reflex camera, it is completely determined through the lens focus shooting, it can see the image in the viewing window and the film is always the same, its shooting range and the actual shooting range is basically consistent, very conducive to visual framing.

The difference between digital cameras and SLR Cameras

1. different structures
And the traditional SLR cameras as the use of the special structure, the digital SLR camera not only completely solve the problem of poor is seen from inside the viewfinder is to change the exposure image on the film, the ordinary digital camera because of the use of CCD photosensitive image mode, everyone to see on LCD is CCD feel. That is to say the photographer saw the image on the LCD screen and you will be taken, there is no aberration, so ordinary digital camera can shoot good macro! So, from this point of view, SLR cameras do not dominate.
2. shutter problem
Ordinary digital camera for ordinary users to shoot a visit to this photo is enough, but the speed of shutter is required to adapt to the harsh environment of shooting photographors is extremely important, in the ordinary digital camera in the fastest shutter speed is very important to maintain in 1/1000 seconds, the fastest shutter speed SLR digital cameras can easily reach 1/10000 seconds, so fast shutter speed for ordinary digital cameras to catch up, the ecological environment is very suitable for shooting.
The 3. lens is different
SLR digital cameras do not support more supporting lenses, and more importantly, the camera indicators are also common digital cameras can not reach the height. First, such as the wide end of the shooting, the ordinary digital camera mostly stick to 35mm ~ 38mm position, a few high-end models to support 28mm wide-angle lens, but SLR digital cameras typically use the original lens can shoot wide landscape photos gratifying, with special wide-angle lens can even continue to expand the visual range. The digital camera is very sensitive to the jitter during exposure even slight shaking will produce a blurred image, if ordinary digital camera is not high magnification zoom lens models, many of them do not take the anti shake function, while the digital SLR camera lens can be applied to prevent the occurrence of instability to jitter shooting in.
The other part of the lens and the image quality is closely related to most ordinary digital cameras and digital SLR camera lens we can see that the ordinary digital camera lens is very small, and the cylinder bore out of proportion, some models of the lens barrel diameter of only about 1/3, while the digital SLR camera lens lens and lens aperture is quite basic, great this is caused by the difference of the two optical system performance force. In short, more than one shot to choose one more point, shooting guarantee, a good lens can make shooting work at ease.
4. area difference of sensitive material
Most of the full frame digital SLR camera 2/3 as the photosensitive material, a small number of high-end products to achieve a full frame (35 mm film and is the same size), more often than ordinary digital camera with CCD large area several times, so the digital SLR general noise is very small, while the ordinary digital camera noise control a lot of difference.

What is a digital camera?

Digital cameras, also known as digital cameras (DC: Digital, Camera), are cameras that use electronic sensors to convert optical images into electronic data. Digital camera and camera in the film by chemical changes of silver bromide to record images of the principle of different digital camera sensor is a light sensing type: charge coupled device; -{zh-cn Zh-tw: more components (CCD) or complementary metal oxide semiconductor (CMOS). The image is transmitted to the computer before, usually there will be a digital storage device in storage (usually using flash memory; floppy disk and CD rewritable (CD-RW) has been rarely used in digital camera equipment).

What is a SLR camera?

In Taiwan and Hongkong, SLR cameras are called “monocular cameras”, and the full name of SLR is “single lens reflex viewfinder cameras”, which refer to a camera with a single lens and a viewfinder with this lens. SLR is not a product of the digital age. There has been a SLR camera as early as the age of film. As the photo carrier to digital SLR with us into the digital age, now we say the SLR is usually said digital SLR camera.
The “single lens” refers to photography, exposure, light path and viewfinder light sharing a lens, unlike the side axis camera or double reverse camera, viewfinder, light path has independent lens. The “reflection” refers to the camera in a plane mirror two separate optical viewfinder viewfinder: fall, the lens light into five prism, then to the viewfinder; when shooting the mirror fast lift, light can be irradiated to film or photosensitive element CMOS or CCD.
