I got in on the Blackmagic Pocket Cinema Camera (bmpcc) fire sale and in preperation for receiving my new camera I have been researching neutral density filters. What I would like to know is what are people's preferences between single ND filters and variable ND filters. And also your thoughts on IR filtration for the bmpcc. I already know if you go the "straight" variable ND route Tiffen seems to be a good trade off as far as quality and price. Dave Dugdale did an incredible review of "straight" variable ND filters. Honestly it is amazing it took an amateur like Dave to do such a test. I see so many posts on the internet from people who could have either saved themselves money or used a higher quality product had someone simply done what Dave did and test them out. These people are pros mind you! So the choice was simply, right? Wrong! I then came across another video showing IR (near infrared) issues with the BMCC... and other cameras including Alexa products. So there are numerous solutions. One could say the near IR pollution thing is nonsense and just get a "straight" Tiffen variable ND. Or you could go with a set of individual ND filters and skip the variable. You could also get an IR cut filter and use either single NDs or variable ND. Or you could get the Tiffen combined IRND variable filter. Or you could get the single IR ND filter sets. B&H has a strong three filter set for $164.50. Okay, that is a lot of options. The reason I posted is I want to know which one will give you the best results. I know the variable NDs have the polarization "issue." Sometimes I like using a polarizer on video so it isn't always an issue for me. Also there is a hack where by you turn the whole filter assembly en bloc to reduce or get rid of the polarization effect. I don't know how effective that is. This guy shows the "hack" to optimize the use of a variable ND filter... Here is a video showcasing the Tiffen IRND variable filter. So what should I do?
