How many times can the micro single lens port be used?

within p>1.5Kg. According to the relevant information, the basic commercially available lenses and bayonet can bear it. There will be a tripod for lenses above 1.5Kg, which shows that it is necessary to use a tripod. And the lens larger than 1.5kg, with the camera, the center of gravity is biased towards the lens, which is unstable from the perspective of shooting stability. Super cannons like those of sports or animal photographers over 3mm can be stuck in time, and it is impossible to shoot with a camera in one hand. The focal length is too long and the jitter is obvious.
