I just got a camera (canon 250d) and whenever I take the lense off the body I get all sweaty and afraid I’ll break it by using too much force. Im always careful with it and I noticed the small square on both the body and lense but I just want to know how sensitive it is. Can I scratch or damage anything if I place the lense wrong on the first try? I’m always thinking I’ll break it if I use too much pressure or twist too much, too little.
Practice at home. Go slow. Go a little bit faster as you get more comfortable. It’s made of metal, not glass. Put it in wrong and see what prevents you from mounting it wrong.
The engineers designed it to handle being used. Your fear and anxiety about the gear are getting in the way of using it. You can get a feel for how much force to expect.
