Q:What is the function of the wide-angle lens of a digital camera?
The main parameters of the optical lens and evaluation of the main parameters are focal length, field of view, object distance, aperture, shutter and so on. The most perfect evaluation of the lens than the MTF (Modulation Transfer Function). However, due to aberration (calibration reasons), each range of the lens has an MTF value. These ranges refer to: (1) the paraxial portion, (2) the off-axis portion, and (3) when the optical system has an asymmetric distortion, the two parts are sub-sections in different directions. Each part has its own corresponding MTF value for different radiation energy wavelength ranges. MTF is the most commonly used and optimal index of the imaging system, and it is also the optimal index to guide the integration of machine vision system.     In the shooting of the distant movement scene, play a key role is the camera shutter speed, which is closely related with the composition, such as children, walking the characters generally more than 1 / 125S can, if the high-speed sports Of the images such as cars and other general in the 1 / 500-1 / 2000S, in general, to be able to shoot the angle to decide.

The better the quality of the UV mirror reflected less light, that is, the higher the light transmittance. Line to sell the camera where there are a lot of online Taobao. The price of 58mm about 65 yuan.
Q:Do professional studio photo, what is the type of camera and lens?
The choice of the lens is generally considered the same as the fuselage, if the money to buy the original head, if the money less, vice head can still do business! In general, the election D300 such a non-full, the lens in the configuration to be cheaper! For example, 50 / 1.4D of the header, that is, studio head (not part) can be full body can be close-up, but also large scene shooting, depth of field virtual enough, high definition! And inexpensive, both inside and outside the scene are practical! As if it is now less than 2000!
Q:The current high-speed camera up to the maximum speed of how high-speed camera with how the lens
Junda Transtech Services 10 series of high-speed camera frame rate of 4000 frames / sec, a small frame up to 25 million frames / sec. Ordinary SLR lens can be used, the specific choice depends on the application, shoot large field of view using short focus, wide-angle lens, shoot fine things can use macro lens, microscope, etc.
Q:Digital camera lens suddenly shrink back? Camera is the Canon IXUS 210 how to do?
In the table pad the book, shut down after the camera at the bottom (tripod screw face) down a few pounds, the intensity of their own grasp the shell is not broken on the line, boot recovery. I have just solved this, I do not believe at the beginning. Very useful.

Q:Nikon camera lens focal length
Introduction to the physical concept of focal length If you read the camera in the English specifications "f =", then the back of the digital is usually its focal length, that is, the length of the focal length. Such as: "f = 8-24mm, 38-115mm (35mm equivalent)", refers to the length of the camera's focal length of 8-24mm, while the diagonal angle of the equivalent of the traditional 35mm camera 38-115mm The In general, 35mm camera lens lens length is about 28-70mm, so if the focal length is higher than 70mm on behalf of the support for telephoto effect, if less than 28mm said there is wide-angle shooting ability. "Focus range" is the extension of the focal length, usually divided into the general shooting distance and close distance, the camera's general shooting distance are usually marked as "from a centimeter to infinity", and near-stage design of the product is often also Will provide close-up shooting function (macro), to make up for the general shooting mode can not focus on the problem.
