[0.7 oz (20 g)] Fine, and dependable ND

[Glass] Good quality, no major complaints.This ND gives a nice neutral look to shot. Not a lot of glare and is easy to handle.

[0.06 lb] I've had the V2 for some time and really like it. Wanted to upgrade for something that could handle a circular polarizer along with other filters and the V6 did not disappoint. I really like the fact that you can rotate the polarizer without needing to remove the other filters.

[0.7 oz (20 g)] I've become a fan of NiSi filters and the NiSi filter system. �These are great filters and very reasonably priced. �I use the ND filters for taking pictures of waterfalls and am starting to experiment with the graduated filters for sunsets. �I bought the system through another outlet, before BH started stocking them. �The system is great with one caveat -- it's easy to lose the the polarizing filter -- hence the need to purchase a replacement :)

I tend to leave the polarizing filter on my camera most of the time, attaching the rest of the system as needed. �Unfortunately, the polarizing filter has a tendency to come off while walking about. �This happened the first time I used the filter. �Luckily a passing stranger noticed and let me know what happened. �I managed to be careful for quite a while, but eventually lost the filter (luckily this happened just after I finished shooting for the week).

[0.06 lb] Nice filter kit! It's great with the extra step rings for a variety of lenses. As another review mentioned the lock screw could cause some problems. You can remove the screw completely to avoid complications. Definitely needed to practice setting up this filter before going into the field.

[0.7 oz (20 g)] I use only Nisi filters and two years ago went from the v5 to the v7 setup. My only complaint is with the v7 make sure that the polarizer is turned so it doesn’t wiggle out. When screwing the filter assembly on and off it the polarizer is not tight it can pop out. I have chipped two of these that way now. They still work as it’s a small chip but causes flare if light hits just right.

If you go with the V7 buy the plastic lens cover that clicks on over the polarizer. It works great and I leave it on all the time now when not in use. Pretty much always attached to my 14-35 lens unless need for another.

[0.7 oz (20 g)] This is my first attempt at a square filter setup. The V6 holder is very easy to install and has various step down rings for adjusting to different thread sizes. The included enhanced circular polarizer is ok and kind of limited on the polarizing effect. Definitely adds some weight to the setup but it's worth it.

[Glass] Can't go wrong with this kit. Nisi makes a great product, worth every penny. No need to upgrade to the V7, the V6 is perfect.

[0.06 lb] Great filter holder kit (holder, case, C polarizer and adapter rings) for the sale price!
The very nice case is larger than I expected.
My only reservation is, as other reviews have noted, the thumb screws on the side seem rather delicate and exposed. Not worried while on a lens but I will definitely use the case while traveling.

[0.7 oz (20 g)] Easy to setup and well fits to my 24-70 and 16-35 lens.
