What's the difference between Canon Xiaobai and Guo Xuwei? Is there a big difference? Does it have a big impact?

Difference, I don't quite understand what you mean.

I use Guo Xuwei now, and Xiaobai has also used it. Now I'll talk about it.

1. From the imaging point of view, there is basically no difference between them. The focal length is 70-200.

2. The aperture of Xiaobai is f2.8, and that of Guo Xuwei is f4. In other words, if white is used, the background can be blurred more beautifully and purer. Moreover, a large aperture means a faster shutter. I don't need to elaborate on this, do I Of course, aperture means high price. When I bought it, the price of Xiaobai was around 9000, and that of Guo Xuwei was 4700.

3. The weight of Guo Xuwei and Xiaobai. Simply put, Guo Xuwei can also sweep the streets by hand. For Xiao Bai, holding it is a very painful thing, so it is usually placed on a tripod.
