The dog head is for some amateur photographers and beginners, and the imaging is average.

However, the prices vary greatly. For example, Canon's 18-55 Dog Head 1300 yuan, 17-55 2.8 yuan is 7,000 yuan.

Hood-a set of lenses, a sales promotion method when manufacturers sell SLR cameras. A camera body with an ordinary lens is called a kit. The price of the kit is significantly lower than that of a single SLR body+independent lens.

Question 7: What are "dog head lens" and "bull head lens"? Dog head lens refers to Nikon's G-type bayonet series lens. In recent years, Nikon has introduced G series lenses without aperture ring, and takes G series as the development direction of Nikon's future lenses. Because of this move by Nikon, this series of lenses can't be used on well-known cameras such as Nikon manual cameras, F90 series cameras and F4 cameras, which has caused dissatisfaction among many Nikon fans. In addition, Nikon's G series lenses first appeared in the form of two low-end small aperture and low-cost consumer-grade lenses, and G is also the initials of gou. Northerners love to use dogs to describe anything that is poor. For the above reasons, the dog's head is scattered. Dog head refers to a cheap entry-level low-end lens. This kind of lens is not clear, and the distortion and dispersion are not handled very well. In the primary stage of optical products, some popular lenses are seriously distorted, and some exaggerated statements can turn people's heads into dogs' heads. But up to now, as long as they are not famous factories and mirrors, they are all called dog heads by boasters. Even a dog's head is a hundred times better than a DC lens. The bull's head is opposite to the dog's head, indicating the head of NB.
