My biggest wish from Red or the team behind Revolva...

[Tom Gleeson]

I am not sure why Bobbys question deserves such a terse response but while Neil is correct in saying that all glass suffers from some light loss this is not really relevant in the context and spirit of Bobbys question. In the old days before modern low dispersion coatings this light loss would add up in multi element lenses but again this is not relevant to the ND question. If I use a clear filter in front of a lens I do not bother compensating for the @4% light loss but maybe that's just me.

Patrick as I understand with the Sony FS5 the electronic ND is physically switched in and out of the optical path. It has a minimum two stop loss when engaged. While a zero loss variable ND would be awesome I have not seen any practical technology yet that can do this? I like the Sony system and would love to see Red emulate it even if they used the existing Motion Mount technology and design it to work in a similar way. Check out this video at the 2min 48sec mark to see the Sony internal ND system in action. https://youtu.be/A9muBcF_QPw
I admit I don't know how Sony adjusts for the change in back focus when the rear ND is engaged? I would guess a clear glass replaces the ND. It is telling that they did not use their variable ND system in their top of the line Venice camera.

Motion mount works on Monstro VV. In VV mode.

As well as the old s35 canon mount. I'm not sure why there is a VV version.

What lenses were you using on the Monstro with the Motion Mount? Thanks

I would add that a Monstro type Revolva would be a Polarizer/ND system.

This will literally bring the MB to be strictly for Shading, no filter trays, no extra glass to carry and replace.

The secondary benefit would be much more functionally lighter MB, either clip on or Road supported.

What lenses were you using on the Monstro with the Motion Mount? Thanks

Testet the Celeres, shot with K35/FDs, LOMO anas, Elites primes 50,75,100,135 and Speed Panchros 40,50,75,100, just from memory so maybe a few more.

There is a reason why the red motion mount is named motion mount and not ND mount. its not really built to use as ND filter but to give the shutter a nicer more sinus wave look. That kind of tech is not really suited to use as an ND as there is quite a bit of colorshifts that comes in play when dialing it up. Somthing that needs to be counter steared in color sience.

we're using the revolva on our Monstro and so far...no problems...but we only tested it with the sigma art lenses, till 20mm....the 14mm vignettes even without the revolva.

Are you shooting at 8K with EF type lenses and not getting any vignetting at all with the monstro?
