<p>Though not responsive to your question (as others have indicated, you'll have to get an estimate from Canon or elsewhere), I thought it might be helpful to remind folks that the carrying strap, when you have a heavy lens on a camera body, should be attached to the lens, rather than to the camera. On a recent trip to Florida, such a lens detached from the camera body and nearly rolled into the marsh. I was lucky, since it fell onto a wooden walkway and still worked. Since then, I've purchased systems which allow me to attach straps to either the lens or the camera body, depending on lens size.</p>
