    Very good points, Bjorn. It would make it perfect.

    Another huge benefit of sticking the filter tray in from underneath is the way gravity works. As if the slot was in the bottom, then dust would not even be half the issue. Better when dust fall out than in :)

    I had a solitaire film printer back in the days, it had one problem tuber dust from a belt drive feel down on the CRT causing black super smal static spots on the footage. It was hell to try to clean it out as new dust fell in while doing it... After moths of problem we realize that if it was only laying down on the side the problem was gone.


    The workaround for the screen issue as it is made now would be one of these raisers from wooden camera I guess.

    Then as I saw where it was discussed on Facebook... if the turrent had focus motor gear on it´s edge, then this thing would solve so may problems for situations when camera is out of reach and you really need to swap a filter. On high cranes, drones, helicopters etc. Just let the AC do it with a zoom motor.




    Curious what the VV issues are that phil mention.


    So looks like a fantastic product with room for improvement.

    Then personally I would want it in pitch black without logo.

    Pitch black would be dope!

    The price point is pretty good, considering the price of a motion mount.

    Could it be that if it was upside down, it would interfere with the fan openings? I don’t have my camera information of me so I can’t check it out

    Convenient that I needed to buy a PL mount sometime soon anyway. :)

    I love the idea of the diffusion wheel as well. Though, I think in usability, it's probably still best to stick to the OLPF approach for those, because I would probably be choosing to stick with one of those for the duration of a project, while NDs can change from shot to shot, even.

    Fan intake is on top and the exhaust is out the back on DSMC2.

    As I'm sure you all understand, we worked through every possible orientation for the Revolva concept. Engineering is all about compromises...

    As you guys are interested, the bare bones of the thought process are as follows:

    To have the rotating wheel concept work, we need glass large enough to not vignette, placed far enough back from the flange not to impede lens fitment.
    This means that every millimetre counts in depth, and it means we have to place the filter wheel at a 45 degree offset from the centre line.

    Lower left and lower right are both obstructed by approx 3mm due to the bulge on the camera's chin. That's even allowing for asking the owner to rip the Red button badge off.
    Upper left and right is fit with a number of accessories, and we identified that an inexpensive riser serves 'hidden benefits' for many users, so wasn't too egregious.
    Upper right places the filter control next to other operator controls. Upper left would have obstructed the sidekick.

    Nothing is perfect, and not every accessory can be cross compatible, but its all about choice. Hopefully we're offering a strong and valid choice for as many people as we can.

    Fans are now on the top and on the back, so no.

    Could be that it interfere with the front of the body sticking out and the microphones. But to me I would not mind having the microphones and the front plate replaced if needed to get this in there.


    Edit:

    John what you done here is magic and a huge step forward. So all my "what if..." comments come from pure amazement of what you done.

    ... But would it be possible if the speakers and the extruding front of the body was removed? :)
