BMPCC4K IRND Test | Vaxis IRND filters with Tilta Mirage Matte box

A simple comparison between regular ND and IRND filters on the BMPCC4K camera which is prone to heavy IR pollution. In this video I'll be testing the Vaxis IRND filter because they are what I have and I very much enjoy the results they give and the system of the Tilta Mirage matte box.
Testing new gear is always important, so if you have the opportunity, do it yourself whenever you get new gear.

Quite impressive for such a "cheap" filter kit. Thanks for the test !

[@MadManchris]

I agree! And I love how nice they are to swich out compared to screw ons or slide in 4x6/4x4 filters. You do have to buy additional filter holders though. But that still leaves each step at about 80-90 bucks.

@@MadManchris That's still fairly decent in my opinion, I'm so glad there's finaly chinese brands coming to shake a bit the market for filters / mateboxes, it can only be positive for us in the long run :)
Thanks again for you feedback !

Love it so far!

Good video comparing the filters. I currently have two BMPCC 4K's and a Tilta Mirage with the Tilta VND and Polarizer. I was looking into getting the Vaxis IRND to help with the lack of the OLPF on the camera. These Vaxis filters seem to help a lot with that. Tilta has recently released a Full Spectrum line of filters for this matte box. Now I am not sure which to buy. Vaxis or the new Tilta ones. Any experience with the new Tilta filters?

Is the issue not more with the lack of IR cut filtration on the camera's sensor construction? I believe most modern cameras run them in their sensor designs but the BMPCC series does not..?

[@MadManchris]

I don't know what you are comparing your point to, but there are several cameras without much IR filtration built in. It's correct that the BMPCC doesn't have IR filtration built into the design yes. It's not an issue if the sun isnt out and you need lots of nd :)

Did you stack 2 irnd filter in tilta filter tray? Thankyou for the video

[@MadManchris]

Yes, the 6 stop is the 0.6 and 1.2 stacked in the same dual tray(sold separate). Still very happy after a year ish 😀

[@Antovmusic]

how many steps recommend for use in daylight? sunny day? for shoot with T1.2

[@cwfilmproduksjon5345]

That depends on iso, shutter speed and how bright it is. If possible I'd try to get a few different strenghts.
In the test you can see I am at f3.5 at 50fps at iso 400 while on 6 stops nd. In that same shot at iso 400, I'd need about 3 stops down to f1.2 and another stop if you are shooting at 24/25 fps. So that means about 10 stops of ND at 1.2, but the sun could be brighter so it's hard to tell exactly.
I'd try to get 2-4-6 stops and the multi tray so you can stack them and get 2-4-6-8-10 stops that way. I haven't tried the strongest steenghts myself so I can't speak for the quality of those, but I'll assume they are pretty good like the ones I own. Good luck!

@@cwfilmproduksjon5345 Thanks for the test! Tell me, do I understand correctly, everything up to 4 stops, a simple ND, can still be adequately corrected, but everything above that already requires IRND?
If this is so, then already having 1, 2, 4 stops of simple NDs, you can also buy one of the most intense 7 stops IrNDs in the manufacturer’s catalog, and dance around its capabilities, sometimes adding iso, and sometimes covering the aperture

[@cwfilmproduksjon5345]

@@Stihl_OK Using nd filters without IR cut is hard to grade at 4+stops yes. Keep in mind this is a direct sunlight test. The ir pollution is not as bad in heavy cloudy weather so if you keep out of direvt sun, you'll be fine at 4 stops. If you own a set of normal nd filters. Do a quick test and see what your pain point is.
If you don't own any yet, I reccomend saving a little longer, if it's within your reach, to buy a filter with ir cut or the mattebox with a dual tray and the 2+4 stop giving you 2, 4 and 6 stops.

[@Stihl_OK]

@@cwfilmproduksjon5345 Thanks, that's an interesting idea. Yes, I now already have regular NDs for 2 and 4 stops, as well as with variable density.

[@cwfilmproduksjon5345]

@@Stihl_OK there are also simple ir cut filters(no nd) but you should do stacking a test before deciding on keeping one.
