Bought to side mount a Speedlite 580 to a Canon 50D with Canon 100mm 2.8 macro attached. I'd checked out a few other non-Canon brackets and felt they were flimsy by comparision. This piece is very well machine, solid and custom designed for the equipment it's joining together. The Canon off-camera cord OC-E3 is included in the price. Most of my photography is out of doors, taking pics of insects, etc, with high risk of equipment damage. The bracket holds everything together securely with no risk whatsoever of the flash unit coming detached. The bracket's solid structure does add a lot to the weight of the overall package but everything's well balanced and sits comfortable for hand-held shooting. The Speedlite can be set at different distances and angles to the camera. If you ignore the hefty price tag then in my view a 5 star rating is fully justified.
