I have used many kinds of cable releases and have now settled for 10 inches clot h cable releases from HP Despite being better than most of this kind, they only work smoothly the first f ew days or so, and due to the bent and constant trauma (why aren't the shutters cable fittings directed towards gravity?) they rapidly start to gripe. I had tri ed to reinforce them with one inch of thermo-retractable electric insulation, bu t doesn't last long either. There are some stronger makes, but the risk for tran smitting movements to the lens is too high. Are there some cable releases better than others? Also, if 10 inches are fine for short lenses, what would you recom mend for long lenses ? Any way to lubricate a cloth cable release?
