Noise
 

If you use external mic, this discussion is not for you. If you use internal mic, I can challenge all the units that using motor to do side by side to compare noise with my unit, this challenge includes mini35 of any generations.

My unit's noise is less than the noise of the camera itself (tape compartment's noise). Giroud Francois made the point there. This unit is right at the mic. In most cases, I found that motor's noise cannot be heard unless there is completely no other noise at all like the moon shooting scene.

Most of the noise come from the motor itself, not the hardware that mounting the GG. I wish you luck trying to use magnet to reduce noise.

When I saw and heard about the mini35, I said to myself, I can beat mini35 by 2 points: motor noise and hand held. I actually did it and offer very affordable price for my unit.

I have a plan to build supporting rods and of course it's steady and affordable. This one is built with light weight aluminum. I don't think that many people here are interested on building this. Tell me if you are interested then I will post the plan, thanks.

I think the supporting rods would be a great idea for those that plan on using a Matte box in the future.

Or a zoom lens, lol. Those things can get pretty massive.

Putting an adaptor in front of the lens to get the film look and recording sound using the built in mike?. What a contrast?

Quyen,

Does your adaptor has interchangable lens mounts?

Please give me time to put together a plan, it's harder than actually build one. I am working to resolve my website problem to post pictures.

My adapter has FD Canon lens mount now and cannot be interchanged. I can make Nikon lens mount too if you prefer. Thanks.

at surplussched they sell adapter mount for M42 (T-mount) to most mount (about 15$ each)

unfortunately this is not usefull for us as we are looking for the reverse.
But i got some of these and there is an interesting thing in them.
the adapter is made from two part.the one emulating the mount (nikon,canon, pentax) and a ring that goes inside the adapter with the M42 thread.
If you can build the same kind of adapter but in reverse.
a M42 (or any other specs.) adapter that can receive a ring with all the differents mount, you could sale a one-for-all adapter.
the user would just need to change the ring according his needs.
these adapter are still usefull if you want to mold the shape of the mount without using expensive lenses.

For the magnet stuff, i think the fact that the power of magnet is not linear is an advantage. the closer they are the strong the force is, so there is no risk of "bumping" the two piece.
for the alignement, i do not think this is a problem , since you can find "levitation" gadget using the same principle and they do not look like hi-tech tool machining.
and finally it is ok the have the center pice trying to escape the force field, since that is helping the gg to stay into the focal plane..
a solution for controlling the stuff would be to have magnet on one side (the center ring) and electro-magnet (coil) on the outer ring, so you can even modulate the voltage to create the vibration. This way you can even generate a patterned movement (circle, flower square).

"and electro-magnet (coil) on the outer ring, so you can even modulate the voltage to create the vibration."

That will only move it on the Z axis or whatever plane you guys call the one that goes through the lens. Electromagnetic force acts perpendicular, not parallel. We just worked with exactly what you're talking about in physics class.

I don't know, the whole magnet thing seems extremely difficult to pull off. I've worked with magnets a lot lately and really don't see this working.

I encourage you all to prove me wrong though! :) lol.
