Does EPIC have a infrared filter build in?

[Michael Kromschroeder]

I have a DoP asking me it the EPIC has a infrared filter build in?

 

[Jeff Kilgroe]

Yes. Yes, it does.

The OLPF on the MX sensor filters out IR pretty well. It can still be an issue in high-IR settings with significant amounts of ND filtering. Best to at least have a good hot mirror as part of the filter kit -- recommended for *ANY* of the new high-ISO digital cameras these days.

Jeff Is right.

If you can test the hot mirrors it's a good idea as stacking to much ND without a hot mirror will cause color casting.

If you need to get to F2 outdoors then you will need hot mirrors.

Thank's guys

Yes it does. And I had a funny experience when testing IR filters for Epic. During that testing I removed the existing IR filter entirely. When I did that, I brought my ND .9 over the lens and it was as if I had placed transparent glass over the lens. So yes, Epic has a IR filter! And in any camera where ND looks like ND, not glass, they have an IR filter in there.

I have one further question, since EPIC has IR filter build in already, i agree to keep one hot mirror just in case.

That would means ND+IR is not really necessary anymore, but i like Pancro being the most neutral ND of all. So what would be the recommendation of the best ND non IR filter ? since some other ND tiffen or schneider doesnt really get you the most neutral color in their ND.

What ND filter that most blockbuster movie used ?

Thanks

Rivai, as you can tell from my story a normal ND filter is effectively an IR pass filter. Once you go beyond about 1.2 ND, you could be allowing much IR to hit the sensor and it's IR filter may not be enough. At that point you're going to need to either move to an ND+IR filter or add an IR filter to your ND stack.

Bending this topic a little I was wondering the other day whether you could put in an order for a modified Interchangeable scarlet for IR. I know there was the ability to order a RED One for it.

 

[RivaiC]

Thx for the clarification Graeme !

Tim wait until the 3rd to ask Scarlet questions please.

Having a hot-mirror in the kit is almost essential. If you shoot outdoors regularly, then having additional IR+ND filters is also a good idea. I own both Pancro and Formatt filters and prefer the Formatt ones. They're just as neutral, if not a bit more so, than the Pancro ones and their sandwiched design holds up better. Or seems to.

IR can be funny... Some environments have a lot more IR to deal with than others. Additionally, the way IR passes through various lenses will differ as well -- sometimes you see more color shifting, other times you may see more aberration-style effects and halos.

I keep IR+ND filters in strengths of 0.9, 1.2, 1.5 and 1.8 in my kit. Along with a hot mirror (which is often equivalent to an ND .3) and standard ND's from 0.3 up to 1.2. In most high-ND (1.2+) situations, especially warm-weather outdoor situations, I will reach for the IR+ND filters automatically.

what would be the best IR filter without ND?

Will a schneider truecut 680 or 750 be good, and which one would be better for the epic?

Or do you need a hot mirror also, what is the difference between hot mirror and just a regular IR filter?
