All ND filters can have issues by their very nature and finding a truly good one is often a gamble. I bought a NiSi Variable ND 1.5-5 stop after reading and watching many reviews and it's not too bad. What is good about this filter is that it's a 77mm filter, but has an 85mm outer ring so that even with an 11mm lens attached, there's no vignetting. It does of course mean I can't use the lens hood, but I have a matte box anyway.

I use the Heliopan variable ND.
While it's quite decent, you have to keep in mind that all of these are basically Polarizers with the typical side effects, like colors on windshields of cars or loss of shine where you may not want it.

Hi, I use the NiSi with IR cut, in 4x4 format. I'm very satisfied with them, I've used the 1.8 (-6 stops) with no noticeable color shift.

Cheers!

I have the Simmod lens Variable ND, so far I can highly recommend it. Outer locking ring has been handy to adjust angle of polarisation. I like the little lever as well, makes on the fly adjustments really easy.

The SLR Magic variable ND has a similar locking ring (looks almost identical in fact) and is also quite good; I've been pleased with mine so far.

In general, though, I mostly regret having chosen to go with a variable ND (for speed/convenience) and a set of circular ND filters. In retrospect a matte box would have been a better decision at the outset.

One problem is that once you start expanding your lens collection, your existing ND filters may not fit all your lenses and you need to get adapters or new filters altogether. With variable NDs there's also the issue of how to add a lens hood. A matte box addresses both of these problems.

Also the Variable NDs works by polarizing the light, so you may be introducing an unwanted polarizing effect.

Sam, that Simmod variable ND looks like a shameless copy of the SLR Magic version I use which has been available for years.

ND filter recommendation?

PostTue Jan 22, 2019 6:52 pm

Brad, I thought I was safe going with 82mm filters for the SLR Magic APO primes, but now I have the Tokina 11-20mm which takes 86mm threads, I’m not able to use my SLR Magic Vari-ND II or my set of ten screw-on IRND 82mm filters! I do have 3 Kenko Tokina 86mm screw-on filters which look very good when I don’t want to use a matte box.

Thankfully I have the eight filter set of NiSi 4x5.65” IRND filters which is my recommendation if the shooter is willing to use a matte box.

Variable IRND filter suggestions for the UM4.6k??! Needs to be IRND and Variable I one, not separate.

Perhaps we are stumped to think of a Vari-ND that is also an IRND.

None that I know of, sorry. This is not a usual combo.

Hi, can I ask as you own an SLR magic variable ND. Does it feel quite firm and solid to rotate the two pieces? Or does it feel somewhat loose? When I first got mine it was firm, and soon became loose. I sent it off for repair and it was firm again, before becoming loose soon after!

I've sent it off again and just received it back in the exact same condition! I'm tearing my hair out trying to get it sorted. But optically I think they are the best VNDs Ive seen

My SLR Magic outer ring isn't the firmest thing in the world so it's a little loose. Having said that, once I set it, it hasn't moved so I think there's still enough friction on there to keep it in place.

Overall, I've been very happy with the SLR Magic but one thing I don't like is that it's usually not strong enough if I want to shoot at anything below 4.0 in direct sunlight. Maybe I'll get that Aurora Aperture to use instead.

Thanks, well mine felt way too loose. It was great when I first got it.

Yes they aren't very strong, but that's to limit the X effect and colour shift problems that stronger NDs suffer from. I bought some Hoya ones and they were awful by comparison, but they were conveniently smaller!

I think I'm going to just get a fixed ND of about 4 to 6 stops, and then I can stack that on the variable ND if I really need the extra darkness.

Are there any issues with stacking a fixed ND on top of a variable ND? Does it matter the order?

The more filters you stack, the more you affect the final image quality. Loss of quality can come from image degradation caused by the filter quality, as well as increased flare etc from too many surfaces in front of the lens.

You can stack as many filters as you like on top of each other, but it's the amount of image quality that you're prepared to compromise that will be something you need to consider. Testing is always important.

If you do go with the option of stacking another filter, SLR Magic IEND Pro 86mm is 4 more stops and an image enhancer. I’ve used it and posted results ages ago. The IEND works well with the SLR Magic Vari-ND Mark II filter you have as it screws into the front of the Vari-ND. It’s a good option to have in your kit.

I’ll also use it as a four stop filter for exterior shots with the Tokina Cinema ATX 11-20mm T2.9 zoom but not at 11mm if stacking another filter on top of the Tokina Kenko 2/4/6 IRND 86mm filters as that vignettes. If I need 8-10 stops in a light rig though, it’s a decent option when it saves using the matte box filters.

Thanks for the tips

Yeah the only time I need more than the 6 stops of the SLR magic VND is when I use my Panasonic 42.5 1.2. All my other lenses can get close to wide in any bright situation that I film in with just the VND.

I also would like the option to use a fixed ND for interview situations as I'm not so keen on using even the SLR magic VND at its darkest

Using the SLR Magic IEND Pro, alone at four stops, should even enhance your image in that situation. You have the even reduction in light, reduction in infrared, sculpting if the spectral wavelengths to resemble the distribution of natural light (by reduction in spikes caused by artificial light sources), and no worries about polarization. Keep it clean and it seems the upsides outweigh the downside of another piece of glass in the path of light.
