- Q:Why Casio digital camera will always show the lens error, and the lens can not shrink
- The lens of the drive components are broken, there may be sand into, or the internal device is broken, repair it! The Telescopic lens prone to this problem!
- Q:SLR camera lens is a unified standard?
- Not common!
Canon, Nikon, Sony, Pentax four manufacturers bayonet is clearly not common. Even if Canon EF and EF-S are not common, EF can be used in full frame and APS-C frame machine, and EF-S can only be used in APS-C frame machine
- Q:Different brands of SLR camera lens can match each other
- But because of SONY's influence in the industry, Sigma, Tenglong, Tuli three plants will provide a basic lens mount lens
With the words of nothing good or bad, of course, on the rich ZA.
SONY deputy factory glasses less, the original set up, but now does not set up, especially Photokina on the horse issued a 5,6 new a bayonet lens and zoom lens and SONY dedicated flash.
- Q:Camera lens material problem
- Weight and this related. Resin afraid of the fire, the glass is better. Glass wearably. Resin lighter. But now the general dc is made of resin.
- Q:SLR camera lens life how to count how to identify the life of second-hand lens!
- In addition, some lens lenses have resin lenses, too old will have aging effects of imaging, this lens is not recommended to receive second-hand
- Q:On the Canon camera "lens error, please restart the camera" problem?
- 3, gently tapping the lens or to force, not too hard, the lens inside a small card astringent foreign body can be eliminated!
4, the above can not be resolved that is a permanent fault, such as transmission gear, track and other jam has to repair
- Q:Digital camera after the start of the lens telescopic non-stop
- The lens is certainly a fault, and their repair can not, if the repair is not here to ask, in this tell you, you can not get, find the camera
- Q:Camera lens into the gray how to do?
- Not much gray words
Does not affect the image
The lens is not sealed
Behind the mouth of the hole
What can fly in
Lens gear between the teeth will also produce fines, of course, the amount of extremely small
- 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.
- Q:The focal length of the SLR camera lens is calculated
- The focal length of the lens is basically the distance between the center of the lens and the clear image formed on the film plane.
The focal length of the lens determines the size of the image taken by the subject on the film. Assuming that the same subject is being photographed at the same distance, the longer the focal length of the lens, the larger the image formed by the subject on the film.
For example, the image taken with a 100mm lens is twice the height and width of the image taken on the same camera using a 50 mm lens. The height and width of the 400 mm lens are four times the height of the 100 mm lens,
Take 50mm as an example. In the full camera do not multiply by the coefficient, that is, 50mm, full-size cameras such as Canon 5D2, Nikon D700. The focal length has a conversion factor on the non-full camera, multiplied by a factor of 1.5-1.6 on the APS-C frame camera. Such as Pentax K5 Nikon D90, Canon 550D 60D are APS-C format. Canon APS-C frame camera is multiplied by 1.6 coefficients.
