Hi guys, 

I've just bought an Alexa, and want a personal Wireless Follow Focus system to use when needed (and when production can't afford to shell out for a proper Preston or current WFF).

Since the camera has the Plus module on it, I figured I might as well try and find an Arri system that would be compatible with it, and I've stumbled across the old Arri "MkII" system, which comprises of:

 

- WFU-1 Iris / Focus Unit

- WZU-1 Zoom Control

- WMU-1 Transmitter

- URM-1 Receiver
- UMC-1 Universal Motor Control

- 3x Lens Motors

 

Obviously, they're pretty old school nowadays, and I've struggled to find much in the way of user reviews/commentary online. So I was wondering if anyone could speak to the system's merits/lack-thereof?

Cheers,

Mark

It is not bad at all, it obviously lacks all the new technologies from the newest models but you can keep everything in focus with it! :) 

I used to have it as a backup for the different Prestons / Scorpios in a lot of movies and commercials in Spain back in the old days and when it was needed it worked perfectly. 

 

I have no idea if it works on an Alexa Plus without the transmitter, but if it does, I would buy this one rather than the older Preston FIZ.

 

Probably it does! :) I'm pretty sure that Greg could tell you a bit more about it :)

 

Have a good day.

I don't know if the older Arri units can be upgraded to White Radio, which is what you need for it to talk to an Alexa.

Thanks guys. I'm getting the feeling the seller was getting a little cheeky with saying 'the kit if fully compatible with the Alexa Plus' - I reckon he means when run through the URM-1 (which would make the system compatible with ANY camera), rather than specifically with the actual Plus module itself.

I often use the old modular Arri WRS, with the Alexa mini. It shouldn't be a problem as long as you have the new white antenna. The yellow one is for older cameras as the 416 for example.

How much was it? I've been thinking about getting one myself :P

Early Alexas also shipped with yellow radio. Arri offered an update.

Also check out the SXU-1 single channel system if it's just for times that the production can't afford FIZ I feel like that's why the single channels exist.

It's compatible with Arri and 3rd party cameras with the UMC recievers.
