Hi Chambesi
. I feel your bad luck, not your stupid mistake.
The single clamp lens foot retainers are a accident waiting to happen, when it does, it is bad luck not stupidity.
Why the mounting base plate cant have the middle third as a clamp and the front and rear thirds of the clamp, be a
Permanent part of the base plate, where you would need to slide the lens foot into it, with a spring loaded pin to restrict the sliding operation of the foot. Keeping it secure if you over look any of the set up method.
This is a system that would safeguard many a equipment from serious damage, when a simple user error occurs.
I had a in depth conversation over the Xmas period, on this subject, as I am selecting a lens mounting system, and
Equipment security as well as performance are on my mind.
The person I was talking to, had another bad luck experience. They watched the cantilever lens mount break off on a Gimbal with a New Purchased 600mm f4 mounted on it . Luckily the tripod was set low, and long grass was under the set up, so no damage happened.
