Friendly or unfriendly, it's definitely not as friendly as the new machine now, but since you've been using the camera for a while, it doesn't matter if you're unfriendly. There will certainly be no operational difficulties. And even if there is, it will be solved by looking through the instructions.

As for what lens to match, you can use your spittoon first, then you can use the second-hand 85 1.8 or the national Yongnuo 100f2, and then you can change the camera body. If you insist on not changing the fuselage, it is Canon's own portrait work lens 85, 70-2000. Students, it's either work or fooling around. Burn more lenses, burn second-hand lenses, so that when the fever goes down, the loss is small, and you can earn a little money if you are lucky.
