Re: Much improved (WAS: Testing a Tamron Adaptall 6.9 200-500mm (not SP))

After reading and practicing the "Moose tips" I have been hooked on
vibrations.

Vibrations should only be a big issue at very low shutter speeds.


My turntable background says that cheapest and most efficient way to
minimise the vibrations is to make the connection to the ground as stable as 
possible.

This makes the case for the most stable tripod you can afford.


This will move the balance a bit nearer the
photographer, making the combo less front heavy.
This is the whole point in a gimbaled head - it balances the camera/lens combo, in effect making it totally balanced, not front or rear heavy. 


It may also be a good idea to fill the tube with led.

Might be a good idea until you have to carry it for a few miles!

I wish you good results with your long lens endeavors.

After reading and practising the "Moose tips" I have been hooked on
vibrations. It looks kind of cool with this "rituals" (self ironic smilie
here).

With vibrations in mind, the King Cobra and the Winberly looks to _wobbly_
on me (pun intended).

My turntable background says that cheapest and most efficient way to
minimise the vibrations is to make the connection to the ground as stable as 
possible. Floating systems can be very good, but the total mass of the
floating system is very critical (by total mass I am referring to the total weight of camera, lens and other moving/movable parts). This suggests that a 
wobbly system can be very good in one lens camera combo, and totally
hopeless in another.
Out of this "logic" I'd suggest going to a metal worker and have him make a 
simple and stable mount bracket, out of a quadrangular aluminium tube, to
extend the tripod mound forward. This will move the balance a bit nearer the photographer, making the combo less front heavy. It may also be a good idea to fill the tube with led. This will add a bit of extra mass (mass is good), 
and sandwich constructions are usually good for minimising vibrations.

This is just some late night reflections from a twisted turntable mind ;-)
So I may be totally wrong about this.
After all, you Kenneth are an experienced long lens shooter, and I'm
definitely not.

How about a gimbaled tripod mount, like a Wimberly or the Kirk King Cobra. 
Done right they basically make the camera/lens combo weightless.
