"One Shot" cable release for Phase one cameras (Kapture Group).
I think this might be the wide angle version but I have used it with all lenses from 210mm-35mm.
If your using a phase one back that requires a wake up signal then you will love this thing! I did when I was shoot with a phase one. This cable release wakes the back up and fires with one push... Very Handy.
