No I used it to whip the elephant that ran amok........well what is a strap for? no where did the instruction say it need to be handled with care and carry up to a certain load (Camera of course plus lens) I used mainly on my D3s and 70-200VR2.....screw direct onto the lens without tripod feet.
I have sent back to Sunsniper in German, postage cost $12.05 (Inclusive of registered mail option) It will take 2 weeks to get there, the 2 day sevice cost about $59.....so will wait and see the outcome.
