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. Subscribe to see EXIF info for this image (if available) 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!
