Found this while looking for shoulder braces when shooting with the Bigma hand held. This is a manfrotto shoulder brace part number 361 and purchased here:
http://www.cameras.net.au/ and very cheap compared to US imports. About the same price as B&H with postage.
A well made piece of equiptment from Italy that does not weigh a ton
Anyone who has trouble holding long lens steady this is a must have overall size 32cm x 3cm and the piece that attaches to the camera is 4 cm wide.....
The front and back pieces move and do not restrict your movement, and a length ajustment, this is about a 1/3 out
This end folds back and is held in position by the lug you see when transporting. Fits under the armpit when shooting, strange at first but does steady the camera
