Last weekend I was playing with new Joby GorillaPod tripod (SLR-Zoom model) with my Canon Powershot SX50 HS. I had to hook QR on the camera and it allows me to release it from mount easily but I am wondering about you professional photographer... do you always leave QR on your camera when it is not in use? Just curious that is all. If you don't understand my english grammar it is because english is not my primary language. Thank you.
