Canon Guo Xuwei, what's the difference between loving Guo Xuwei and loving Xiaobai? What occasion are they suitable for?

These three lenses have little difference in appearance, the main difference is the different performance of internal optical elements.

Specifically, there are two points:

1, different aperture

Xiaobai: The maximum aperture is f2.8

Guo Xuwei: The maximum aperture is f4.

Love Guo Xuwei: compact and lightweight f/4 telephoto zoom L lens.

The maximum luminous flux of Xiaobai is twice that of Guo Xuwei. Under the same lighting conditions, you will get higher quality photos, but the cost will be much higher.

2. Different anti-shake functions

Xiaobai: There IS no IS image stabilizer equipped with hand shake compensation mechanism, so it is not anti-shake.

Guo Xuwei: No anti-shake.

Love Guo Xuwei: It has optical anti-shake function (Love is the homonym of the English abbreviation I.S.).

Love Guo Xuwei can eliminate the adverse effects of fuselage jitter on imaging system to a certain extent. In addition, Guo Xuwei and Guo Xuwei have the same function.

3. Different characteristics

Xiaobai: Built-in focusing can be used in outdoor sports, scenery, portraits and other extensive shooting fields.

Guo Xuwei: It's smaller and lighter. Built-in focusing system and ring ultrasonic motor ensure fast and quiet focusing. Because the front lens group does not rotate during focusing, the lens can be easily used with a polarizing filter.

Guo Xuwei: Optimized lens coating and lens position can effectively suppress ghost and glare, excellent dustproof and waterproof performance, circular aperture brings excellent defocusing imaging, annular ultrasonic motor makes focusing quiet and fast, full-time manual focusing, and all optical systems are made of lead-free glass.

In terms of applicable occasions, because the focal lengths of these three lenses are all 70-200mm, their applicable scenes are the same, and they are usually used in sports photography, portrait photography, landscape photography and other occasions where telephoto zoom lenses are needed.

General principles of lens selection for Canon SLR cameras

1. For ordinary consumers, you can choose the camera factory hood, which is generally 18-55mm focal length, and the mid-range model is equipped with 18- 135mm focal length lens. If you need to shoot portraits frequently, you can buy a standard portrait lens (about 85mm focal length, f 1.8) to cover the general shooting needs without causing too heavy economic burden.

2. For those who have high quality requirements and like to take landscape photos, you can choose 17-40mm lens, which is a typical representative of Canon wide-angle zoom lens with high cost performance.

3. Those who like "bird shooting" (that is, long-distance photography) can choose 70-200mm lens, that is, Xiaobai and Guo Xuwei series. This series of lenses is expensive, so you'd better do what you can before buying.
