There is a SLR 60D+ 18200. My student photographer needs an extra telephoto lens. Budget 5000-8000 guidance.

Give up XXB and go straight to ISXXB. It's expensive but worthwhile. If the telephoto lens is unstable, you will have great pain. If you want to make up for it by high sense ... hehe. I won't talk about the imaging of 18200. After pushing it to 150, the meat was a mess. Come out. It will be super wide when there is a landscape shot, Sima 1020 or Tuli11. Going to Longteng's A 16 is a big deal.

The best shot that Canon telephoto can take is Love Guo Xuwei. Fat white is very good and heavy. You can take pictures and exercise.

You asked so many questions before about how the original factory Changjiao came to the vice factory again ... You pay the price to get what you want, but don't buy the vice factory, especially Changjiao, if you can buy the original factory.
