I have read over the years that the B1 can lock-up. I never paid much attention since mine never had any troubles, until now. I was shooting the National Day parade here in Singapore and my tension knob locked in the open position. Does anyone know how to unlock it? It wont budge.
It had been working fine the few minutes before. I took my tripod down to move and when I went to set up again, it was locked.
Thanks in advance.
