Heden has a new motor available. It's apparently 3x times smaller and lighter than the DM-2! Great for Iris or Zoom applications.

Interesting, any idea on price? It's Preston compatible correct?

yes, it's Preston compatible and should cost less then $1500. Please check with Magnus.

update, received my motor this week. it works great, tiny and lightweight, the perfect motor for Iris use or tight spaces around 3d rigs....cost is around 2K......

How strong is it? Have you had it on any stiff lenses?

It really is a second motor no? You need something stronger as your primary motor?

I was told it has the torque of a DM2. i'm using it primarily for iris/zoom applications, but you can use it on S4 or ultra primes as focus motor without a problem......it comes with a set of gears for all standard lenses and integrated bracket.

i have 2 of them as part of my Cmotion kit. They are much smaller/lighter than the 26's

They are surprisingly powerful. Along with my new cvolution handset I can boost the torque of this motor. So far it has been able to handle all the lenses (no primos yet), I have even used them to move IO and convergence just to see if they will do it....so far so good.

So it's highly recomended.....

Thanks for the reply Jens!

Daniel Stilling posted up a sound clip a couple of weeks ago demonstrating how quiet this motor is. Here's his post for those who are interested.

Woops. Ours is a M26VE not the 21. Still nice and small and suprisingly powerful.

Anyone know what the torque spec is?
Since the motor is so short do you find that you need to use a dog bone most of the time? With the 28 I find I never really need to but it is a much longer motor.

Note about some heden motors,

All my heden motors 21's and 26's came with my C-motion Cvolution kit. My FIZ kit is 3D ready so I have 8 motors! I choose to have 6 26's and 2 21's.

I use the 2 21's when I do 2D....but like I said previously they have turned everything I have used them on....


Cmotion sends special boards to heden, they use those boards in all the heden motors they ship to cmotion that they then include in their kits.

Cmotion claims that performance is improved and reliability is better via improved "grounding" of the new boards.

Thus they do charge more for them :rolleyes: and they recommend using thier "heden" version motors with thier equipment but naturally regular hedens and preston motors still work just fine with all the cmotion equipment...

Exception is that with the previous Cmotion receiver you need a special cable to go c-motion to preston motor. The new "cvolution" receiver you can use the same motor cables with the heden motors and preston motors which is great new feature.


I'll see if I can get torque specs from Sebastien from C-motion/Camadeus.... for 21 and 26....
