Newbie - setting up gh1
Posted 21 February 2011 - 09:54 AM
I've been through the dvd, manual & user cookbook settings a number of times and seem to be reasonably close but, no cigar yet:-)). However, I appear to be miles away from any user cookbook settings on my GH1 &, although I'm getting a slow drop time it still seems to be very pendulummy. The user settings I've tried seem to be way off. Perhaps I'm way off in my understanding & handling.
My Settings:- GH1 with 14mm pancake: weighs 500g. Front= finish: Bottom= finish & start: Mount Hole= H: Platform= -0.25 Caliper distance = 230mm: Z turns -7 from closed although -8 gives it a lovely slow drop.
Presumably the idea is to be carrying the least amount of weights required to balance the camera to zero & then fine trim to get level, then fine tune Z to get the drop? Does it seem to someone more knowledgable, that I do not have enough mass (ie weights) on the Merlin to give it some sort of bulk to steady it a bit?
I look forward to hearing back from you & cracking it.
Many thanks David

Any ideas out there what to add? A aluminium tripod plate ain't that heavy and, I would imaging one doesn't want to raise the camera's CG too much.

(my understanding is inertia is driven by the SQUARE of the mass times distance from the gimbal)
Some Rails will lift the camera and have some mass
Becuase the camera is very compact unlike a 'long' video camera I think rotational inertia is low
You can maybe configure with more mass at the front and close the spar to compensate maybe
I have done things with rails and adding a little mass at the rear of the rails to add rotatinional inertia
I think adding a plate is not such a bad idea to lift the camera a little, spreading the mass from the gimbal, it could also aid a transition to sticks or handheld rig
