Please help me choose the right right 77mm 0.9 IRND

[Kamilla Lusa]

Hi guys,

I really need a 0.9 IRND filter (screw-in 77mm) for an upcoming project.
Read all the threads on Reduser about IRND filtration but still have my doubts.

I was able to narrow down my choice to:

1. Formatt 77mm Hot Mirror/Neutral Density (ND) 0.9 HD Filter
2. Schneider 77mm MPTV Platinum IRND 0.9 Filter

Has anyone used any of those? I really want to avoid crazy tints and have IR contamination free image...
I am leaning towards Formatt myself.

Thanks you your thoughts,
Kamilla

A 3 stop ND filter should not require IR rejection and most good quality brands should be OK.
It is at the higher filtration rations that IR contamination can become a problem.

Hi Pawel,

thanks for your response, however from my tests I can clearly see that when I use 0.9 regular ND filters (I use Tiffen) my footage suffers from IR contamination in usual problematic areas therefore I am looking for a solution.

I have a set of 4x5.5 Schneider IRNDs and I would imagine there is no difference between them and the 77mm versions. I like the Schneiders, and they're available from B&H in 77mm. Been meaning to pick one up myself for my Canon glass when I'm running without a mattebox.
