I have two big telephotos. One is a MF Nikon 200mm f/2 AI-S. The other is the Olympus 150mm f/2. Lenses that are this big havetheir own tripod mounts in order to avoid strain on the lens mount when tripod mounted. But my Nikon also has build-in connectors for putting a strap on the lens itself so that when I have it with me, it can hang over my shoulder. That, one, makes my arms happy and, two, puts the weight on the camera/lens combo on the tripod ring rather than on, again, the lens mount. It turns an otherwise miserable lens to take on a walk with you into something no worse than carrying a laptop messenger bag around. Does anyone have any suggestions for something even remotely similar for the Olympus? The Olympus 150mm f/2 weights 1kg less, but is actually more frustrating to carry because of the lack of anywhere to attach a strap on the lens!
