Self-Takes Part 2
Since my original bulb release split, the mechanism being permanently fixed to my adaptor bracket, I have been using a second bracket which I bought when I thought I'd lost part of the first one. Having used it for a good few months now (although not recently...) I think it's better than the first one as it locks more securely in all places and being aluminium and steel construction the thread the release screws into shouldn't strip like the plastic block did.
The part that screws into the camera's base is also less likely to be lost as it is captive in the channel of the bracket. I've slipped some aquarium tube over the ends of the posts to stop them slipping out in transit. The only thing to watch out for is a thumbscrew working loose and getting lost.
The bracket (and the replacement bulb release) were bought from SRB-Griturn who have since proved very helpful with other orders for photographic accessories. To be safe order the angled version which will accommodate any angle of shutter button. A larger version for SLR cameras is also available.
