Need a little help...I'm new to canon and I just bought a canon 5d3 with a 70-200 2.8 ii. I've only had it a week, but I'm worried about the way the lens connects to the camera. It screws on just fine, but when the 70-200 is on the body and I'm walking around carrying it, it will slightly...very slightly...feel like it's a bit loosely connected to the body because it will "jiggle" ever so slightly with each step if I carry it in a verticle position(lens pointing down) and I'm holding onto the body in my right hand by the grip. And if i hold it the same way and just gently shake it up and down(repeat, gently) i can feel this slight "jiggle" sensation in the connection. I went back to the camera shop I bought it at and tried their demo lens on their demo 5d3 and i could feel the same sensation, so that made me feel better but the problem is that a i've never felt any of my other lenses do this...the guy at the camera shop says its normal for long heavy lenses to do this versus smaller lighter lenses
Help please..any thoughts
