SLR Camera What is the difference between a card camera

The differences between DSLR cameras and other card cameras are: 1) The lens can be changed, and you can use a fixed focal length lens or a telephoto lens with different focal lengths. 2) Low-end SLRs can basically achieve a shutter speed of 1 4000 seconds, and mid-range to high-end SLRs can reach a speed of 1 8000 seconds, while ordinary card cameras cannot do it.

The highest-end card type can only be 1 4000 seconds, while the ordinary ones are around 1 1600 seconds. 3) Because the lens can be replaced, the choice of aperture value is very wide, it is very large, all the way to the very small F22, and the card camera because the lens can not be replaced, so the aperture is fixed, and it is usually two-stage, which means that if the widest angle aperture is not the longest focal aperture, the choice is rarely enough to fully meet the needs of different scenes. High-end card cameras have more options, but they still can't be compared with DSLRs.

4) Basically, a DSLR can be connected to an external flash, while a card camera can only be connected to a high-end one, and an ordinary pocket camera can basically not, and the distance of the flash is very limited. 5) The other is that the photosensitive system of the SLR is basically CMOS, while the card camera only uses CMOS for the high-end ones, and the ordinary ones are CCD. The chip of the SLR is also larger, and the sensitivity is better.

The high-end SLR can reach a full ISO sensitivity of 25600, while the highest-end card full set can only be 3200. 6) For the framing part, the Wuling mirror or pentameter mirror used by the SLR has a better refractive effect on the light than the general card-type digital camera, so the subtle reflection of the object or the depth of the color light should be more accurate. The cheapest Canon SLR kit is around 3,500 to 4,000, but the lenses in the kit are usually insufficient.

Basically all SLRs can be captured instantaneously, because the shutter can reach 1 4000 seconds. The mid-to-high-end SLR can do 1 8000 seconds, but the price will exceed 10,000 yuan.

The card machine is generally a consumer-grade product, with simple functions and fashionable shapes, which are more suitable for carrying, such as Sony's T300 and Canon's IXUS series; The home camera you mentioned should also belong in this series. In addition, some telephoto cameras are also more popular now, and their functions are more similar to professional cameras, with a larger zoom factor, which belongs to quasi-professional cameras, such as Nikon's P80, Sony's H50 and so on. To put it bluntly, a single-lens reflex camera is also called a single-lens reflex camera in Hong Kong, the lens and the body can be separated, and different lenses can be configured according to different needs, it is the most complete in terms of function and quality, it is also divided into different grades, entry-level, medium format, full-frame, etc., such as the latest Sony A900 (full-frame), the relatively early Canon 450D, Nikon's D300 and so on.

At present, the ** of the SLR is also falling again and again, and the ** of some fuselages has reached a fairly low level, which is also the trend of future camera development.

The zoom of the card is small, and the pixel height of the SLR! The shutter lag time of the card is longer than that of the SLR, so the capture of the wonderful moment is not as good as the SLR! But the operation of the cards is simple, and the size of the cards is relatively small! SLR is definitely expensive!

The CCD area of the SLR camera is much larger than that of the card machine, and the lens can be replaced through the lens framing lens, and the imaging is good The card machine is generally relatively small and lightweight, and the imaging is worse than that of the SLR.

Much worse SLR is a single-lens reflex digital camera card camera is a camera with electronic framing, and electronic framing is not as intuitive as mirror framing, so it's much worse.

Differences: 1. The lens is different: the SLR camera is a telescopic lens, and the card camera is a hidden lens.

2. The optical zoom is different: the optical zoom of the SLR camera can reach more than 10 times, and the optical zoom of the card machine is generally only 3 times.

3. Different framing methods: SLR cameras are cameras that use a single lens, and the light shines on the mirror through this lens, and the camera is framed through the reflex. The card machine is viewed by a photoreceptor with an LCD.

4. The size of the body is different: the SLR camera is generally 130 mm long, 80 mm thick, and 90 mm high, and the card machine is generally 60 mm long, 40 mm thick, and 50 mm high.

5. Whether there is a manual function: The SLR has a large number of manual functions, which can be easily used for manual zoom and manual setting of shooting parameters. The card machine is designed and hall for easy carrying, the function is not strong, it is generally automatic, and there are few manual functions.
