I currently own a Canon 200D and a friend of mine borrowed me a 24-70 F2.8 lens for playing around. The lens weighs 800 grams, which is double the weight of the camera itself. Putting it on I was slightly afraid of bending the lens mount if I hold the camera body without supporting the lens with my second hand.

We're those fears justified? Or can I safely mount any lens on any compatible camera without worrying about the weight?
