    Built-in electronic Variable ND Filters

    The FS5 features Sony’s unique built-in electronic variable Neutral Density (ND) filter, further expanding the depth of field capability of its large format sensor. Unlike conventional optical ND Filters, the electronic ND Filter on the FS5 can be controlled from 1/4 ND to 1/128 ND linearly. ND Filters can also be set to auto.* This makes the FS5 ideal for fast-moving shoots in changeable environments — there’s no need to change filters as lighting conditions change, and variable control makes it easy to keep depth of field under control.

    BTW, Sony is notorious for having a spiel for the marketing department that omits technical details that could be seen as negatives. That is potentially forgivable, most companies stick to the positives for obvious reasons. What is irksome about Sony, is what appears to be a deliberate strategy to bury certain specs.

    I'm pretty sure everyone does that as much as they can get away with- Sony is no exception what so ever.... Sometimes they get caught but they know very well that uneducated consumer has a short attention and memory span so they don't seem bothered much with the occasional "busts". We have all the power in our wallets and absolutely refuse to use it....I have not been able to comprehend that and probably never will....

    Alex,

    Panavision have modified the optical path on the DXL. The Colour Filter Array (CFA) that sits on top of the CMOS Monstro chip has been Panavised and changed for a "better" one. Michael Cioni said Panavision could afford to build a better CFA as cost was not a factor. This means that the chip is seeing colour in a different way to a Red Monstro. Like you I also assume that Red has a different configuration of lightwave frequency cuts built into their bespoke OLPF? This means the "out of the box" Light Iron science will not work in a Red Monstro. People can build LUTs that emulates the LIcolor2 LUT and they may get close to the look but it could never be exact as the two cameras are seeing a different balance of "colour" in any scene.

    Sony maybe has an NDA with itself.

    That’s a pretty good question, I imagine having to only design LiColor2 to work optimally with one OLPF and three sensors (excluding the DXL2) is a lot easier than 3+ OLPFS for each sensor.

    I was under the impression that the CFA was laminated into the sensor "sandwich" and not a swappable layer. Interesting...
