Q:Can the Canon SLR camera lens be generic?

The adaptability of the above three kinds of bayonets can be summarized as follows: 1, EF bayonet camera, the lens for the versatility is relatively poor, can only use the EF mount lens, but the vast majority of the current lens, especially high-end lenses are EF bayonet. This type of camera is mostly full-frame camera, representative models have 1Ds series, 1DX, 5D series, 6D; Secondly, 1D series is not the full size (APS-H format), but also must use EF lens; again, Canon early APS-C frame models (before 2003), because EF-S bayonet has not yet come out, can only use EF lens, on behalf of models D30, D60, 10D 2, EF-S bayonet camera, the lens is very versatile, in addition to all the EF lens can be used, you can also use all the EF-S bayonet lens, but no matter what kind of lens, the actual focal length are Equivalent to 1.6 times the focal length of the lens. This type of camera are APS-C format camera after 2003, on behalf of models are: 7D, 70D, 700D, 1100D and so the vast majority of Canon in the sale of entry-level camera 3, EF-M bayonet camera, in a sense for the lens of the versatility is the strongest, in addition to matching the EF-M lens can be used, you can also install the adapter ring, the use of all EF and EF-S lens, focal length conversion factor is also 1.6. At present, only Canon's no use of the camera (in fact, that is micro-single, just because the name of the micro-single registered by Sony, and other countries can not be used), on behalf of models: EOS-M and EOS-M2

Q:What is the meaning of the VR on the camera?

The camera's safety shutter is based on the countdown of the lens focal length, such as the focal length of 50mm, the safe shutter is 1 / 50s, if less than the shutter speed, in theory, it is easier to produce jitter. From this point we can understand that the longer the focal length, then the shorter the safety shutter, if the telephoto lens focal length to 300mm, its safe shutter is 1 / 300s, if the shooting conditions are not ideal lighting conditions, then very Difficult to reach the safe shutter, hand-held shooting jitter is difficult to avoid. VR damping technology can reduce the shutter speed of 2-3 files, so more conducive to the light conditions are not ideal at the same time can not use a tripod and other equipment in the case of shooting clear photos. So compared to professional high-end SLR lens, in the home digital camera popular VR anti-shake technology seems urgent. Especially in the telephoto digital camera, anti-shake function becomes more important. Anti-shake generation (VR) and the second generation (VR II), generation can reduce the three shutter, such as 50mm lens, do not open VR to have 1 / 60 to clear, open the VR generation, down three shutter, that is, 1/15 seconds can be clearly shot, the second generation down four shutter, cheap lens only VR switch, a little better lens mode selection, a normal mode , A chase mode, suitable for making animals, cars and so on.

Q:Why is the SLR lens so expensive?

Said the white lens is a few optical lens group, said white IPONE, computer, etc. These are some electronic devices, the cost is not high, why the cottage phone to sell hundreds, genuine to thousands.

Q:Camera lens points can be stretched what can not pull what is called what

Can not be stretched called "fixed focus lens", the focal length of the lens can not be changed, to change in the lens to see the object of the distance, it is necessary to rely on man step.
