I had issues with this one. I couldn't find my L-shaped cable release extender thingy and my normal air release cable has too much plastic around it to fit on the lens and fit the lensboard back on the camera. Even had issues with my normal 3ft one... it wasn't quiet on for the first picture so it jammed in the ON position when in Bulb mode so the exposure was about 6 seconds while i figured out wtf was going on
Couldn't rotate the lens on the lensboard, rotated the lensboard itself and it was still hitting on things. Really need to find that expensive little piece of metal!
