  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Epic's swappable sensitivity ISO 25-250//ISO 200-2000

I like this idea. Is there more IR filtration in the higher ND OLPF?

Nope, BTW - I don't feel like getting an answer to deliverytimes. Whatever is useable by late september is great though.

As to the question of shooting sub 320, I guess that this is stil a camerasensor, that will have some downsides to effective DR....
There has been some good examples here of "But it may work", but those are based on images that don't challenge the actual limits.
 
I fell in love with this feature when I saw it at NAB but afterwards there was one little niggling where I could see it getting annoying. There doesn't look to be anyway for the camera to show what internal filter is being used. I can just see people forgetting to change the filter, or forgetting to check at a rental house and thus people end up shooting with an internal filter they didn't plan to.

It's not a biggie, and maybe you guys have fixed it, but if the camera GUI showed which filter is installed internally that would be awesome!
 
That's an interesting question. How will the r3d meta data treat these OLPFs? It's kind of standard practice now that we assume "320ISO = Native Sensitivity". If you did have a UI setting that modified the display of just the ISO there could be confusion if someone saw a 50 ISO r3d but that was actually a "320iso" under the hood for debayering.

I would say Sam if they did implement a UI setting it would be only a label but not actually touch the ISO settings to keep things consistent (just as if you were shooting with ND, not a "lower sensitivity" sensor).
 
Would it be possible to have something like a filter wheel built into the lens mount, so you can rotate it and choose your ND strength? Or a place to slide the ND filter into the mount like an old 16mm camera?
 
Very nice feature, I was hoping for something like that.

Can it be changed in the field, or do you need to be in a safe place to be sure to protect the sensor ? I guess if you remove the OLPF, there is nothing protecting the sensor anymore for a few minutes...
 
This makes a lot of sense. I know of shooters who really wish the RED was ASA 50 as they do a lot of daylight shooting.

It will be no different than putting an ND in front of the lens. No change of metering, metadata or monitoring is necessary.
I do agree, though that it would be good to let the user input a display option flagging that the filter is in there. Really, it would be great for a big indicator to briefly flash on the screen on startup.
 
Does Epic have any sensor cleaning or dust checking feature?

Changing OLFP is extremely dangerous, specially when in a hussle. Swap an go could be a no go...

Just playing the neverinding skeptical here... ;-)

Then don't do it. We have a lot of customers that wanted a solution so we made one (good one IMHO). Fincher was the 1st to ask us to solve the problem.

I guess that's why God invented camera tape.;-)

I love this idea. I noticed at NAB there were a few other options on show as well as just ND. I'd love to be able to swap out to an IR camera with 4 (plus 4 for the mount) screws. I promise not to mention the AA filter...

Does it effect focus at all like when gelling behind the lens with a film camera? Or does it not because it is glass?
 
Same thickness so no change to back focus distance.

I believe any material placed behind the lens affects the depth of focus about 1/3 of the thickness of the material. If you're just swapping out the same thickness of material it shouldn't change the the depth of focus.
