The M is light enough for any strap. When I was using the 40D with heavy lenses, I use neoprene strap. It is very comfortable. However, I do not use quick disconnect type of straps. I am being skeptical. The more connection you have, the more chance to go wrong and drop your camera.dswtan said:Op/Tech Cam Strap - QD for me! Inexpensive, simple, effective. The elastic neoprene style may not be for everyone. Previously I used a generic nylon weave non-elastic style wrist strap on my compact cams. I'm not sure which I prefer at this point. I like the quick release on the Op/Tech -- though I never use that in practice!
