Hey there. Anyone had any luck using an Omnishot with Sony FM50 batteries on an HU1 rather than HU2?

Thanks

Thomas

The Omnishot fits both Preston hand units since the battery mounting interface is the same.

Yes, I'm aware it fits. Has anyone tried using it or is currently using it especially with a microforce. Does anyone know the power consumption on the HU1? Preston haven't responded to my emails.

Hey Thomas try speaking to Chris or Russ at Optical support, they are very smart with all things Preston related and they are also the uk dealer.

I've been using it for over 2 years. No problems.

HU1, rarely with a zoom though.

Are you sure Brad that you are using it on an HU1 rather than a HU2?

I have found success using the Omnishot with the HU1 so long as the focus puller doesn't turn the HU1 off. If he turns it back on afterwards the lowlight jams the system. This is particularly bad with the microforce connected. I am having far more success with FM70 batteries rather than FM50's.

Clearly the HU1 sucks more power than the HU2 and requires more "surge power" to start it up. This is too much for either my batteries, Omnishot or combination of the two.

Omnishot have been insanely helpful helping me through this problem which has included sending me another unit to help me diagnose. My conclusion is that the Omnishot works better on the HU2 than the HU1 and I would still recommend it on the HU1 but:

Focus Pullers don't turn the unit off at all (a lot don't like to anyway)for fear of that battery not re-sparking the HU1
Focus pullers check both lights are on and green before every shot
You stock up on FM70's rather than FM50's

This still works out to be the cheapest battery solution for the HU1 by a large margin! and I have only good things to say about Omnishot support.

There is still always a chance that I have an issue with my low voltage circuit on my HU1 so I would love it if others would share their experiences of using an Omnishot on an HU1.

Thanks

Thomas
