No. :cool:

In fact Josef tested the head´s strength with that kind of configuration. No problem.

best, Klaus

But a VR sphere is not possible :) im afraid....but who would want a 800 mm VR sphere :) (excepts some whack Londoners of course).

BTW, you have a pretty balanced situation on there Klaus so the center of gravity is verry much near the centre of rotation. So what you are stressing is the axel of the vertical drive (in fact the ball bearings on the axel of the vertical drive, get the most stress). A small but more of center lens/camera could produce more load on the geartrain and on the vertical stepper motor backlash gear (as some of my experiments with a talk meter show). But never the less the Panoneed is one hell of machine.

. . . and that´s why we of course tested it very much off-center too for finding out when the time comes to better switch to 4 Nm.

Regarding the fact that such lenses are used only on quite long distances there´s no need at all to match any kind of NPP - and due to that fact there´s no deed to off-center it´s fixing.

What is extremely important: avoiding ANY kind of vibrations - even when using mirror-llock and very short exp. times. So a REAL stable tripod is essential - and very helpful are the vibration-sensors which are integrated in the Panoneed.

All agreed Klaus,

for long lenses I'll be integrating this or some of it's relatives in my head:

http://arduino.cc/en/Tutorial/Knock

......but first I have to check it's inate stability, it uses 2.4 kg/cm motors and specialised (bespoke) 20:1 anti-backlash worm gears and industrial bearings (SKF) since mehanical engineering is not my forté as of now so I (and my parts supplier) opted for a decidedly Roman approach (a little more can't heart) then go the Chapman way....make it lighter until it breaks which can be done with a panorama head a lot easier then with a F1 car, and then look for a radical new approach if needed (goal is still 1.5 kg and OM-D + 300mm stable/usable at least I have no mirror to worry about, have I).

So i've got my work cut out for me.

Greets, Ed.

I have my Panoneed on a Really Right Stuff Versa Series 3 tripod with a leveler and a clamp (I installed a dovetail plate on the bottom of the Panoneed). Vibration is not an issue on that platform. Highly recommended!

Here's a video of it:
