Q:Is the lens of the camera as long as possible?
When shooting stars, the moon and very distant scenes, the longer the better, the more able to play a smaller perspective imaging function. But to shoot near the scenery, the collective photo and other large viewing angle of the scene, it is necessary to play a wide-angle lens. So that the length of the camera lens focal length and the subject matter of the shooting.
Q:Why is the SLR lens so expensive?
For the lens of the optical system, the first to be designed, the cost of the design according to the requirements of the lens, good optical design to tens of thousands are possible. We see some of the lens imaging will be some purple edge, or image distortion, etc., these are caused by optical design, for these effects it can only take into account some of these aspects, the whole should have a good imaging, with aspheric Right now. And then the lens of the material, the lens of the different prices of different materials, some in order to correct the aberration must use a series of glass, and this glass price is more expensive.
Q:How long is the life of the SLR camera, how long is the life of the lens?
The life of the lens is mainly dependent on the use of the situation at the time of storage, as long as no external strike and excessive moisture in the air too much impact will not affect the operation of the lens moving parts. Of course the current lens such as Canon, Nikon also used the electromagnetic aperture and auto focus motor is also a factor affecting the reliability of the lens. But usually also less frequent use of damaged reports, only accidentally broken or internal wet mold can not be used.
Q:Canon SLR camera lens d100 and Canon 5d series lens can be universal?
You want to ask is 100D and 5D it Canon D is behind, D stands for digital camera.
Canon SLR currently has two main specifications of the lens. EF-S half-frame lens and EF full frame lens. EF-S and half-frame fuselage as halves, so the cost is low, the price is cheap, the quality is correspondingly worse. EF full frame lens and full frame opportunities like the use of materials, relatively high quality, the price is high.
Q:What is the difference between a digital camera CMOS lens and a CCD lens? Which lens is better?
The current situation is that many low-end entry-type digital camera using cheap low-grade CMOS chip, imaging quality is relatively poor. Versatile, advanced and professional digital cameras use different grades of CCD, individual professional or quasi-professional digital camera using advanced CMOS chips. On behalf of the future development of imaging technology X3 chip is actually a CMOS chip.
CCD and CMOS which is better can not be generalized, but in general, the popularity of digital cameras in the use of CCD chip imaging quality is better.
2CCD dead pixels and repair problems shooting night or cover the lens cover for a long time exposure, the image of the color point is not necessarily CCD dead pixels, some noise, CCD temperature will be improved after the upgrade, through the firmware (Firmware) upgrade Some can also improve.
Q:In the camera lens, 1 / 2.3 inch means what it means
1: in the camera lens, 1 / 2.3 removed in., The meaning should be the lens aperture 1 / 2.3 that F2.3.
2: 1 / 2.3 inch, as Lou Sheng said nothing to do with the lens, refers to the size of the camera photosensitive components. Ie diagonal length is 1 / 2.3 inch (11 mm). The aspect ratio is generally 5: 4.
Q:Digital camera lens suddenly shrink back? Camera is the Canon IXUS 210 how to do?
The battery did not power before the tube will shrink back to their own, so that the situation can only say that it is broken, you gently knock twice, take the body knock, not to take the repair, and if you did not fall, Then you go to complain to them. This is the problem inside.
Q:Digital camera lens brush can brush lens it?
Put the dust clean and rub
Do not have any lens water to rub directly
It is not necessary to be so careful that the glass is so high
Moreover, the small dc is also nothing is very cunning of milk x is the coating
Q:What does the lens on the camera lens mean?
The new actor in the camera before the fear of fear, stage fright
A lens turntable on a camera or television
Q:Digital camera lens how will there be a shadow ah?
Is the possibility of dust is relatively large. Remove the lens to see if the air can not blow off, if it is no way to blow the inside of the lens. Such as the supplier can change, if not for, to see whether the impact of imaging, do not affect the words do not go to customer demolition of the lens, the impact of imaging was demolished, there are some lens inside the factory with dust.
