Which is better, Nikon vr2 lens or ed2 lens?

First of all, we should popularize the significance of ED lens and VR anti-shake.

ED lens: Because the refractive index of light with different wavelengths passing through the same optical lens is different, in telephoto lens, color burrs (such as purple edges) are easy to appear at the edge of the image. The ED lens developed by Nikon can effectively correct this phenomenon. Similar lens Canon is called UD lens and Longteng is called LD lens.

Chromatic burrs are more likely to appear in telephoto lenses, so advanced bull heads such as 70-200 focal lengths can even be corrected with 5-7 ED lenses.

It is found that the color saturation of lenses with more ed lenses is obviously increased, and the "oily feeling" of the film is also increased, so enthusiasts are very concerned about the amount of ED lenses. Nikon 17-55/2.8 gold ring Tau uses 3 ED lenses, and the color and oiliness of the lenses are amazing. However, the lens chromatic aberration burr of 18-55 focal segment is not obvious, and even if it is not used, there is no obvious purple edge phenomenon, but the color saturation and oiliness will be insufficient (this is more the photographer's subjective feeling). 18-55VRII lens only uses one ED lens, and it is hard to say how much contribution it can make to the improvement of color.

The VR anti-shake function can keep the viewfinder picture stable and reduce the image blur caused by hand shaking during shooting. VR anti-shake can improve the shutter speed of third or even fourth gear. For ordinary photographers, there will be hand shaking more or less when shooting, especially when shooting with telephoto lens, which is easy to cause paste and cannot be ignored. Someone put forward the concept of safety shutter. Generally, when the shutter speed is higher than the reciprocal of the focal length, it can effectively prevent the film sticking caused by hand shaking. For example, for a 200mm focal length lens, the safety shutter should be 1/200 seconds or more. After turning on VR anti-shake, the speed of the safety shutter is reduced by four steps, and it can reach 1/50 seconds without pasting. A 18-55mm lens, with a maximum focal length of 55mm, an equivalent focal length of 82.5mm at the telephoto end, a safe shutter speed of around 1/80s, an equivalent focal length of 27mm at the wide-angle end, and a safe shutter of 1/30s, is easy to realize under general light conditions. Therefore, this short and medium focal length lens has low requirements for VR anti-shake.

Nikon's two lenses are priced at the same price, so there is no difference. Those who prefer dark light can choose VRII lens, and those who prefer color and image quality can choose EDII lens. Compared with Canon's entry-level 18-55 lens, Nikon's 18-55 film quality is really better, so you can buy it with confidence.
