Anyone using the Revolva with Canon L series lenses on the monstro?

I am just curious if anyone is using this combo with success? Any sample footage you can share? Also what are the limitations?

You may find that you experience some gate shadow with very direct beams of light hitting at very acute angles on the sensor.

See example below:

Just curious what would be causing that outcome? Is it something common you see alot of when using that combination of the monstro and revolva together? For the most part does it work well? Reason why I am asking, I have a monstro coming in and wondering if I should sell the revolva off my gemini if it doesn’t work well together with the monstro.

I'm sure John could phrase it much better than me but as it's designed for S35 the 'window' is smaller than the one on the VV mount, see the image I attached to hopefully illustrate the difference there, so imagine putting the S35 mount on the VV sensor. When light comes in and hits at an acute angle it shadows on the sensor as its covering the VV sensor.

I know John has said a few people do run it with the Monstro's and just as long as you are aware it can happen you can avoid it such as with a matte box, additionally depending on the lens you might see some vignetting.

Always important to do your own testing :)

Lots of people use revolva with Monstro. It wasn’t designed for it, but in most cases it’s absolutely fine.

For clarity the shadow Jonny’s referring to is the thin strip across the top right of frame in that image. It can happen even with regular OLPFs and with smaller sensors too, dependent on light position and lens type. Revolva makes it more likely to occur, but it’s unlikely to be a deal breaker.

Yeah have seen the same thing with only the normal OLPF on Red.

Sans Revolva.

What are the focal length limitations with using full frame cine lenses with the revolva and monstro?
