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.
The mount where the lens physically connects is usually very solid. The stuff inside the camera is much more delicate, fortunately it’s nearly impossible for the lens itself to reach inside far enough to damage anything. Just don’t go poking inside with your finger or a stick.
