    I believe Kholi intends to test the filter this weekend when he completes another Sketch (and will have an URSA).

    I'm about to setup a test with my xrite. It won't be extensive:

    - variND at minimum and Maximum with without IR
    - Hoya ProND matched min and max with and without IR
    - VariND + Hoya ProND to create a stronger VariND with and without IR

    On pocket, 2.5K, 4Kprod, and Ursa

    Thank you as always for your extensive tests Kholi! If you're ever in Orange County hit me up, first drink's on me.

    Eep it was actually Hook that did the tests on the Hoyas! I just sniff around for goodies and go by feeling haha. Although in this case, had JB not mentioned the IR thing I probably would've passed on this specific Vari because it does have a green cast up front.

    Will update soon.

    2.5K Camera @ 5600K, Sigma 18-35@4/35mm
    Shutter Angle to adjust for exposure instead of iris.

    SLR VariND - MIN - NO IR


    SLR VariND - MIN - HOYA IR


    SLR VariND - MAX - NO IR


    SLR VarinND - MAX - HOYA IR


    HOYA4(0.6) - NO IR


    HOYA4(0.6) - HOYA IR


    HOYA64(1.8) - NO IR


    HOYA64(1.8) - HOYA IR


    HOYA4 + SLRVariND-MAX + HOYA IR


    It took a few tries to get this right, light moving etc., but after seeing these I think I can personally approximate performance on the other cameras.

    1. So glad we found Hoya ProNDs.
    2. SLRMagic + Hoya IR CUT seems ready to go.
    3. SLRMagic IR Pollution exists, but seems to be pretty minimal in most cases. Should be fine to correct if you're okay with that.
    4. SLRmagic + Hoya4 + IRCut might work if you need a really strong VariND
    5. Couldn't detect any sharpness hit with SLRMagic VariND
    6. SLRMagic VariND color shift isn't massive, especially with IR Cut behind it.

    Given that the IR CUT + VariND works out so far, I think the only thing that's really needed is to put a ring behind the SLR VariND for polarization.

    Seems like a good alternative to me if you really want to run with a VariND. Still need to explore flare etc. But it's a start.

    Minor thought: I think the ProNDs have varying levels of inherent IR Cut from the design, it looks like the 64 cuts more IR than the 4. Makes me wonder about stacking again.

    Thanks, Kholi. On the BMCC, IR Cut does seem like a good idea with the SLR Magic vari-nd. I look forward to your results shooting the tests with the URSA/BMPC4K sensor to see if the results are identical. To my eye, it does look like the vari-nd is a great option when you want its convenience and 77mm thread size, and only need up to 6 stops of filtration, but put an IR cut between it and the lens. The problem may be trying to find that filter as the world discovers SLR Magic has a winner.

    I cant seem to tell the difference between the Tiffen VND + Hoya IR with the SLR Magic VND + Hoya IR, other than that the later one cost $50 more.

    Being optimistic the results would look promising on the Pocket. ProND is still king, not expecting the VNDs out there to beat it nor match it.

    Thanks Kholi

    @Kholi. As always, thanks for the test!
    What is your best real-world estimate of the minimum and maximum ND of the SLR Magic VND?

    Also, that Hoya4+SLR Magic VND+Hoya IR Cut is substantially blurrier than the others. Was focus off or was there just too much glass in front of the lens?

    Nice test Kholi.

    I know some have stated "you don't need IR Cut with the HOYA PROND", this also shows that there is still a benefit of running an IR Cut filter with the HOYA PROND. While the HOYA PROND do a good job of cutting IR it's clear they still let some through.

    Thanks for Kholi for the test. Looks like Hoya IR Cut is still relevant, the question is should I replace my Genustech vari ND with the SLR Magic Vari ND?
