Vertical movement of a DSLR mechanism ?

[AllEx]

Do you have any sugestions to make on a vertical movement mechanism (steady) for my DSLR rig (this would only have to move my camera) ?


Thanks in advance.

Hello Alex,

Many tripods have a vertically movable center column but I am sure you know that.

Have you looked at focusing racks?

And here is a Tripod with Rack and Pinion Geared Center Column:

or a geared head? http://www.bhphotovideo.com/c/produc...ared_Head.html

I think it might be easier to get suitable suggestions if you present the rig and tell us in more detail what you want to do. I would guess that you might not only want vertical movement, but perhaps also some adjustable mechanism for automatically tilting the camera while raising it, to keep the subject in frame? (Assuming it is intended for video.)

Assuming Video - Buy a Steady Cam Rig.

Basically, you'll pay for the quality and functionality that you get.

Thank you for your replyies, Bill i`m not intending to do a video rig (in fact I`m doing Macro), and I am not inderesting in tripod head Dank (i do have a tripod with a vertically movable center column). To be more precise, as Domeij said, I`m thinking of a plexiglass rig in witch in one edge would be the stage (witch would move my specimen horizontical and it would have, for a particular reason, larger vertical movement. I thing I saw something in Ted`s sugestion "savazzi racks". The mechanism i need is a simple vertical devise witch would move my camera wih Stack Shot combination that would stand on the oposite edge of the plexiglass rig. Tomorrow I was searching the net to find something with no result, for the moment i would take a closer look in savazzi racks.

If you intend to build it yourself, I think the micro-movements for a macro rig could best be accomplished with screws - at least one pair of screws (to avoid torsion on the system) that are differently handed, left and right, coupled with cogwheels, so that both do the same movement when turned. Driven by hand or with a step motor, I think movements for stacking could be accomplished.

Maybe more suggestions could be found at http://www.photomacrography.net/

I`m in http://www.photomacrography.net/, initialy I planed to solve the problem with a lab jack, but due to the facty that it adds more instability to the system i am now thinking of something that it would be taking advantage of the small movement of 10mm of my stage, and my extra 2 and 3 mm plexiglass plates that i made. It`s a litle bit complicated but since the all thing is not proposed to work with a variety of lenses but only with 3-4 the most 5 of them (objectives) I`ve desided not to make something like the thing with the cogwheels that you describe.
i`d rather work with a stable hight on my camera-StackShot system and move only my subject.
One way or another thanks for sharing your thoughts with me.

I have an old device for twin lens reflex cameras - designed to remove the parallax error when close up, that with a twist lifts the camera about 30mm. Essentially it is fitted between the tripod head and camera.

Now one of these, with a set of shims would be ideal for your objective - the device lifts with a lever and can be locked in the upper or lower position. It would be easy to use this with a set of plastic shims - lift, place shim, let down, photograph, lift, place another shim, let down .....
