What lens is blurred in Jiao Wai? Ready to start with SLR, brand model is still hesitant?

The best lens for blurred background is 70-200 (constant aperture 2.8). Especially when using a large aperture, such as 2.8.

-3.5, even if the subject is close to the background, the effect of background blur is good. And the imaging quality of this lens is also great.

As for which brand of SLR camera to choose, these major brands Nikon, Canon and Sony have their own characteristics, and the supporting lenses are relatively complete. I have always used Nikon's SLR camera, and I like this brand.

I don't know if the above answers will help you choose a lens and camera. Welcome to communicate.
