Q:Is the camera's lens longer and more expensive?
In fact the manufacturers for the use of convenience, do everything possible to make long short.
So the short thick lens will be more expensive.
Amateur telescope long, but you can weigh the weight to know, where there are few pieces of the lens, the general is also very fine.
A 200mm f / 2 lens is not long, but the thick bowl of the diameter, making it worth more than thirty thousand yuan.
Are talking about the vernacular, hope you can understand.
Q:SLR camera lens has a slight spot-like moldy how to do? Is it sunny?
Can try, but can not guarantee useful.
If the lens is better, it is best to repair it, looking for professionals to do lens maintenance mold.
If you want to do it yourself, you need to open the lens (hands-on ability is not strong, do not understand the people please do not split)
Q:SONY camera lens stretched out
Machine failure, although you did not fall, there may be your family, friends moved the machine accidentally broke it, repair digital machines, unlike the general appliance repair, of course, the cost of high, before my one Kodak machine put In the camera lights battery pack, was burned out of electricity, take the past to repair 500 yuan, I did not repair, and now still, bought a new Canon 450D. But your problem is not too serious, the maintenance staff like how much will be how much, no way,
Q:24-70 What does the lens mean?
24-70 refers to the focal length of this lens is 24mm-70mm, is a standard zoom lens. 24mm wide-angle end, 70 telephoto end.
Q:Canon SLR lens how to choose?
2, even if the high quality requirements, then 24-105 is not suitable for 50D use. Because 50D is a non-full-frame camera, the lens will have a 1.6 times after the coefficient, that 24-105 multiplied by 1.6 after the 38-168mm, the telephoto end seems to account for cheap but wide-angle loss is serious, almost no Wide angle at all. So this lens is not suitable for use in non-full frame machine, it was originally as 5D2 full frame machine sets of head with. Some people say that you can use the patch to make up for this approach is feasible, but the specific operation is more trouble, a trip down to do a few can, but if you need to do a bunch of wide area scenery, it weighs you.
Q:Card camera lens dirty, how to clean up?
Blow the dust and then do wipe. Generally for a watermark, stains, as soon as possible in time to clean up, like saliva or acid, alkaline rain stains on the film have a slight erosion, a long time may damage the membrane surface. Clean the way the lens is a breath, with the lens paper in the lens surface to clockwise or counterclockwise one direction to rub, must not rub back and forth, wipe the point is: light into, slightly wipe, and then light up as a process, And rub a process, we must change the site and then rub. Suede is a good lens wipes, but the quality of artificial suede, do not use the good. Natural suede if there are parts hardened, must not be used, easy to scratch the lens. The current consumer DC lens is very small, with the lens paper or suede are not necessarily able to wipe, rub the whole, recommend the use of special lens pen, one end of the brush, used to brush off the dust; the other end of the Run suede head, the area is very small, but the use of good results, can be used to wipe the small lens on the mark stains, and large mark on the stains do not need to do a large area of wiping, the only drawback is the price Partial expensive, cheap 50 yuan or so, good quality about 200 yuan.
Q:What is the meaning of the VR on the camera?
VR (Vibration Reduction) Camera Anti-Shake Technology is an optical technology that improves image blurring due to camera vibrations and allows you to shoot quickly when you lower the shutter speed by three steps, allowing you to take clear pictures with telephoto lenses. When the photographer shoots the moving object, the system will even automatically detect the movement of the camera, VR operation can only be carried out in the newer Nikon camera. Today, the Nikon VR anti-shake system and Canon IS image stabilization system by many consumers that the world's first development, the most influential two optical anti-shake system. Not only was a large number of professional SLR lens, but also often in the consumer level digital camera to see its shadow. Which also laid the Nikon VR anti-shake system in the field of optical image stabilization in the professional status. Nikon VR anti-shake principle and Canon's IS image stabilization system is basically the same, are the use of the lens in the floating lens to correct ldquo; optical axis offset rdquo ;, by the detection part, compensation vibration lens group and drive control part, In the electronic damping system to detect the slight vibration of the lens, real-time correction of the lens inside the lens position, effectively reduce the external vibration on the impact of the final camera imaging. Nikon VR anti-shake system can reduce the safety shutter to the third gear.
Q:How do I clean up the fingerprints on the camera lens?
SLR refers to single-lens reflex viewfinder, that is, SLR (Single Lens Reflex), which is today's most popular viewfinder system, most 35mm cameras are using this viewfinder. In this system, the unique design of the mirror and the prism allows the photographer to view the image through the lens directly from the viewfinder.
Q:What does the lens 50mm mean?
ou said this refers to the lens focal length, because the lens focal length is the basic knowledge of photography, although very simple, but let you from the theory to the actual understanding or need to say a lot, give you find some information to see:
Lens focal length: refers to the lens after the main point of the optical distance to the focus of the lens is an important performance indicators. The length of the focal length of the lens determines the size of the image, the angle of the field, the depth of field and the perspective of the screen.
The focal length of the lens is a very important indicator of the lens. The length of the focal length of the lens determines the size of the subject on the imaging medium (film or CCD, etc.), which is equivalent to the scale of objects and images. When shooting the same subject with the same distance, the image of the lens focal length is large, and the image of the lens is short. According to the different uses, the camera lens focal length difference is very large, there are short to a few millimeters, more than ten millimeters, there are up to a few meters. More common are 8mm, 15mm, 24mm, 28mm, 35mm, 50mm, 85mm, 105mm, 135mm, 200mm, 400mm, 600mm, 1200mm, as well as up to 2500mm long telephoto telephoto lens.
Q:What is the impact of the camera lens on the quality of the photo?
But more important is the level of shooting, exposure of the technology for whether to get a good picture of the impact is much higher than the impact of the camera and the fuselage for the photo.
