FREEWELL82mm Versatile Magnetic Variable ND (VND) Filter System

First few times you use them is great, until you want to add other 'magnetic' FX filters that end up being smaller than the front of the VND one, incredible oversight that severely cripples this system.Additionally they add quite a strong yellow colour cast which can be difficult to colour correct, especially for those that don't set the white balance after the filter is on the front end.The new K2 version is unfortunately not much better, although the colour cast is less noticeable.But also there, you can only use one FX filter at a time and if you can forget using them for most matte boxes too since they are huge (don't fit properly into designated camera bags once on the lens.Seems the only way to get truly accurate colour is to use non variable ND's

I like the product, that's why I ordered it and it is what you expect it to be, especially if you watch a couple of YouTube review prior to ordering. But in this case, I have to rate it this low, just because how inconsiderate the seller of the product is. I got the item clearly used, even though being sold as brand new. The package wasn't sealed, all filters were covered in smudges with fingerprints and the lens cap had scuffs all over. That is unacceptable for something that expensive and in general for a product of the optics/photography category. Very disappointed by the seller, will have to find elsewhere to buy where I can be sure it's actually new.

I personally prefer Polarpro, as every time you want to take one of these filters outvof their holder, they are marked by fingers while pulling them out. Also, you have to take them out all and read their label to select the one you want. The amount of time spent on this is more than screwing and unscrewing Polarpro filters to/from the lens. Also, I don't find the strength of the magnets sufficient. While taking one of these filters out of their holder, one might lose it on the floor breaking it. All in all the benefits of being magnetic is outweighed by insufficient practicality of handling them. I return mine just a few hours after receiving them. For me Polarpro has raised the bar when it comes to protection and handling of these expensive filters. Sorry Freewell, but to win the competition from Polarpro you would need to address these weaknesses like Polarpro has.
