In an attempt to make my life easier I bought a cable relase for each of my LF lenses. The idea was to attach the cables to each and leave them that way in my camera bag, ready for use. It turns out that some of the cables frequently came loose, and even fell off the shutter. Upon close inspection, it was clear that not all the cables had the same number of treads. The picture shows the one on the left (the generic brand) with a much shorter thread than the Nikon cable on the right. The Nikon never leaves it's shutter. Did I just happen to buy some defective/really bad cables, or do I need to ask about the threading before buying? Which cables to you use/recommend? I didn't think this would be so complicated....
