Hi, I am selling a used analog Bartech. Everything is verified to be in working order. More pictures can be seen here: http://imgur.com/a/M4r4c Asking for $2000 USD or Best Offer. Shipping is extra. I'm selling from Toronto, Ontario, Canada. Local pickup can be arranged if it works better for you.

Neat. The only situation where I can see this being an issue is that sometimes in tight sets, the camera is already too long and the operator is already asking to have the back battery taken off. In that scenario, it isn't quick to move the MDR somewhere else. You'll need to change out the mounting system to put the MDR elsewhere on the camera. I think a good way to mitigate this issue is to build in a 3/8" screw so you can quickly screw it onto the handle or something in those scenarios.

Sorry for the delay in reply. It fixes the input issue. It now recognizes HD-SDI signals reliably. I am not sure if it fixes the latency issue because I haven't had a chance to test that problem.

This problem seems to have been corrected since firmware version 3.0 and higher. The latest 3.1.1 does not have this issue as far as I can tell with my monitor.

I just recently had the pleasure of using the RTMotion MK3.1 on a shoot. We only had 2 motors. And I opted to only use one to keep the rig light (handheld all day). As mentioned before, the receiver is incredibly small. Maybe the size of a pack of HubbaBubba chewing gum. The motors seem to have a proprietary 4-pin Lemo connector/cables. The motors were very quiet and responsive. However, if you do try and make a quick and large focus rack, you will notice the motor can't keep up. Although maybe I didn't tweak the torque settings correctly. Not a huge fan of the mounting options for the motor because you can only put the rod-bracket on one side of the motor. Also the butterfly tightening knob does not ratchet and that actually caused some problems for me. Very easy to pick up and learn to use if you've used any other wireless follow focus systems before. Range was decent. I was shooting inside an old brick-walled apartment with lots of wifi signals everywhere. No discernible interference. And signal passed through at least one wall with no problems. I never had a chance to test the range fully. There was no lag between the hand unit and motor. The unit does auto-calibrate and you will need to mark rings like you do with a Bartech. Other other minor gripes: - No way to lock the controls as far as I can tell. Example, if I set an iris stop and I don't want to accidentally bump it, I can't lock it. - There are these two thumb knobs near the top left of the hand unit. I suppose they are designed for zoom control or inter ocular control. Them being so small, means there is no way to mark them.
