I have a need for an air shutter release on steroids. My requirement is to trip a copal "press" type shutter. Since press shutters don't have a "T" setting, t he ideal air shutter release should be able to trip and hold the shutter open wh ile in the "B" setting.
I have an inexpensive (~$8) Tundra air shutter release which works great with st andard copal shutters, but is just shy of being able to trip the press shutter. I purchased the Hama air release from B&H (~$33) and found it to be identical t o the Tundra except a $25 label which said "Hama" was placed on the reel. It wa s returned, and now I'm back to the drawing board.
Any leads on a heavy duty air shutter release would be appreciated.
