You can check the flatness of any filter by looking through it with a telescope or one side of a pair of binoculars. They were marked "Multicoated," and weren't! I was given some Crystal Optics brand filters, and they weren't flat, leading to fuzzier photos. I avoid off-brands like Quantaray and Promaster. Nikon has always made exquisite polarizers. If I want a multicoated filter, only the UV and protective filters come that way. Nikon (and I presume Canon, Minolta and Pentax) filters are also excellent, however, they only come in a limited range of colors and coatings. I also prefer Tiffen ND grads over others because Tiffen grads are both made of glass (others are plastic) and really are neutral (others often have slight color tints).ī+W and Heliopan are excellent, but they are bigger, klunkier, not always as well coated, and blindingly expensive. Tiffens also are laminated glass, so when I shatter one, it stays as one piece with fewer deadly shards. Uncoated Tiffens can be washed with soap and water between my thumb and forefinger under a faucet. I use Tiffens when I need mechanical durability. Hoyas are also the least expensive filter brand, so couple Hoya's low prices with highest quality and I'm sold. Optical glass making involves a lot of trade secrets, so if Hoya makes something someone needs in a lens design, even if they know exactly what the glass does, they still can't make it themselves. Hoya also makes special-order glass when lens makers ask for it. Not that anyone goes on record about this, but as far as I know, everyone, including Nikon, Canon and Leica, use some Hoya glass whenever they need certain types that they can't get elsewhere. Hoya has been the world's largest maker of optical glass for decades. Hoya filters, except for some weird ones like multi-image and grads, are solid glass.
#GOLD FILTERS FOR PHOTOS SERIES#
I'm told that there is a cheaper series of green-box filters that aren't coated, but I haven't seen them. Sure, Nikon makes a multicoated UV (元7c or NC), but if I want an 81A or A2, Nikon only makes single-coated filters. Hoya also makes multi-coated filters in every color I can imagine. This is because even the least expensive Hoya filters that I've seen have always been coated to prevent ghost images. Hoya filters have been my favorite for decades. The specific product lines may be ignorred, but the rest holds true. Alpha polarizers are uncoated, which is fine since we don't shoot polarizers into the light anyway. NXT polarizers are uncoated, which is fine since we don't shoot polarizers into the light anyway.Īlpha: these use a simpler multicoating on conventional glass, and still have first-rate optics and metal rings. NXT: Excellent multicoated filters, on conventional glass. (the older HD2 and even older HD lines are discontinued the HD3 is even better.)ĮVO: Add an anti-static, fingerprint-resistant multi coating, but use conventional (breakable) glass. Ultra-tough unbreakable glass, hard oil-resistant multi coatings.
I just got the scoop on their latest filter product line. They constantly come up with better filters, and cancel old styles faster than their online catalogs can keep up. Hoya, the world's largest maker of optical glass, improves its filters so often that it's hard to keep up.
