Just read a post here about filters which got me started on this question:
Is there a "Best" brand for filters or no?
I've read articles where different brands were "tested" and shown to give different results than one might expect or want.
I have stayed mostly with Singh-Ray and Lee (Little/Big Stopper) filters. Just wondering if there is a less expensive alternative that produces the same results.
Many manufacturers make two or more series of filters at different quality and price levels. Cheaper ones with lower quality and fewer features versus more expensive ones with better quality and more features.
If you're using oversize, rectangular filters... Singh-Ray and Lee are among the best. Tiffen also makes some very good ones, but in limited sizes and they ain't cheap! Arri and Formatt-Hitech are a couple more high-end makers of square & rectangular filters. A lot of the "more affordable" sqr./rect. filters are optical plastic and uncoated. There's nothing wrong with optical plastic, except that it's pretty easily damaged, harder to safely store and difficult to clean. Multi-coatings are good to have on all types of filters, but may be more important on sqr/rect. than than round screw in, because the sqr/rect. filters are more difficult to shade effectively. The "better" filters may be glass and have multi-coatings, but you should check carefully because it varies by the type of filter, too.
If you are asking about round, screw-in filters, the list of manufacturers is a whole lot larger, and among those there are a lot that are making top quality. Again, it can depend upon the type of filter. For example, B+W Circular Polarizer in their very good F-Pro and top-of-the-line XS-Pro series are among the very best, but are priced far less than many comparable filters. Compare those to Heliopan, for example, which are virtually identical specifications for twice the price! Breakthrough Photography's X4 are very comparable, too... and priced somewhere in between B+W and Heliopan. One of the more expensive of this type filter are Hoya's "HD3", which lack some features offered by B+W, Heliopan and Breakthrough.
Hoya has taken stratification of their products into different quality/price niches to the point of ridiculousness... For example, B&H Photo lists seven different Hoya Circular Polarizers ranging in price from $55 to $199 (not counting their "Moose Peterson" C-Pol combined with 81A warming filter, which serves little purpose on a digital camera). That's out of a total of 54 77mm C-Pols by 29 different manufacturers (not counting any "combo" filters), ranging in price from $7 to $285 at B&H Photo!
But if you look for Neutral Density filters (not "Grads", the solid type in various strengths)... There's little to no price advantage to B+W, though the quality remains among the best. Might be worthwhile to shop around, though.
There are some relatively new manufacturers who appear to be very competitive with their pricing, such as Gobe and Benro.
And there are also innovative companies, such as Kase and Freewell who are both offering magnetically attached ND filters, which may be handy when you have to remove the filter to focus and then reinstall without bumping any settings to take a shot. That technique is sometimes necessary when working with stronger ND filters. And will likely be easier with these magnetic filters, than with the screw-in type or the square/rectangular type that slide into a holder.
Some old manufacturers are doing new tricks, too. Cokin filters are widely known for their huge range of affordable, uncoated, plastic square & rectangular filters in several sizes, along with a system of holders to be able to mount them on a variety of lens diameters. The company is under new ownership and in the last year or so have introduced a new "Nuance" line of filters with high-end specifications, in both rectangular types and some round, screw in.
Usually, but not always, you "get what you pay for". For example, at $194 the Canon branded 77mm C-Pol is one of the more expensive. It's a decent filter, but nothing special and not multi-coated (B&H says it is, but I had one and it definitely isn't). I'd wager it's a rebranded filter from Hoya or someone else... not actually made by Canon. Rebranding is fairly common among camera and lens manufacturers... along with premium pricing. I bet Sigma, Sony and others outsource too. Older Nikon filters weren't multi-coated, but their new "II" series supposedly are ($140 for 77mm C-Pol). B+W and Schneider Kreuznach are subsidiaries of the same parent company. So are Heliopan and Hasselblad. Sony and Zeiss are related, too. Tokina, Hoya, Kenko are all under same ownership, as well. (THK used to own Pentax, too... but sold it to Ricoh. There there still seems to be some cooperation on products, though.)
