Helping to reduce reflections and glare, the 46mm Linear Polarizer Filter from Hoya filters out light that has become polarized due to reflection from a non-metallic surface. By filtering this light, a noticeable increase in the saturation of skies and foliage is possible, as well as the ability to produce clearer imagery when photographing in hazy conditions. The filter is constructed from optical glass and is mounted within a durable, lightweight aluminum ring that has a hard-anodized finish to guard against wear.

A linear polarizer differs from a circular polarizer in that it does not support the use of a camera's autofocus or auto exposure functions; it is best suited for use with manual cameras, such as view cameras, that are not dependent on internal mechanisms to determine focus or metering settings.

Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light.
Clears up haze in distant landscapes and provides more saturated, vivid colors.
Strongest effect when used at a 90° angle from the sun.
Optical glass construction maintains image clarity.
Aluminum filter ring is both lightweight and durable and features a hard-anodized finish to guard against scratching and wear.

    46mm Linear Polarizer Filter is rated 4.5 out of 5 by 4.
    Rated 4 out of 5 by from Inexpensive Polerizer that works Seems to work well and not as expensive as the Circular filters......just point the arrow generally in the direction of the sun to get maximum effect....It definitely livens the blue sky and green grass as well as reducing glare...in my small Olympus 4/3 camera with no viewfinder I can't really see any difference in the amount of effect being applied so I just point the arrow in the general direction of the sun and shoot....see images uploaded shot in RAW then edited to increased EV if necessary, etc

    Rated 5 out of 5 by from Excellent filter All I ask of a UV filter is that it do nothing - that is, that images taken with or without the filter are identical. This one did its job ably, and was not hard to clean or get on and off. Unfortunately I lost it recently, and am replacing it with a B+W, since the Hoyas are out of stock. If the B+W is any better than the Hoya for twice as much, I'll be surprised.

    Rated 5 out of 5 by from Replacement polarizer glass for Leitz / Leica POOTR / 13352? The Leitz/Leica "swing out" polarizer was produced in various versions from 1939-2004 when I believe it was replaced by stock number 13356. The 13352 units are known for separation of the glass/polarizer/glass laminate, which introduced one or two air gaps into the stack and can ruin the device. The original laminate is made with two glass disks, one, furthest from the film, is of slightly larger diameter than the other. The package is glued into a brass ring and clamped and glued into the rotating portion of the 13352. It is about 2mm thick in total.� Removing the glass / polarizer / glass stack from the Hoya is a good "drop in" replacement for the original brass encircled package in terms of diameter, but not thickness. The Hoya glass is approximately 1mm thick. The threaded retaining ring from the 13352 does not reach deeply enough to the 1mm thick Hoya glass to make mechanical contact. Tilting the filter back and forth, one can hear the glass tip and make a little noise. Since the original 13352 was glued together, I was able to glue the Hoya glass in place before screwing in the retaining ring, and then add a little glue on top of the glass, on the retaining ring side, to take up the gap when I installed the ring. Before the glue dried, I was able to rotate the Hoya glass with the same suction cup I used to place it in the rotating body of the filter, so that the polarizing axis aligned with two retaining holes visible from the rear when the filter in its "swung out" position for choosing the proper filter rotation. I used a second polarizing filter, with its axis marked, as a reference to find the axis for the Hoya glass. The result is a filter that works perfectly. Since the mechanical restraint relies on glue in one direction, I have some concern that pressing on the filter in the away from the lens sense may cause it to break out of the glue and loosen. So, I plan to be particularly careful cleaning it on that side. Naturally, this repair was not accomplished with Leica parts and Hoya never intended their filter to be cannibalized in this fashion, so, neither company is responsible for the combination. Further, filters repaired in this fashion should not be compared with used filters where the laminate filter stack has remained in good condition. However, I believe that if you have the tools, manual dexterity and can construct the necessary jig to prevent the filter from rotating when it is disassembled, this represents a "partial success report" for using the Hoya 46mm linear polarizing filter as a parts source: The filter is the proper diameter to replace the original stepped brass ring containing its glass/polarizer/glass laminate however it is TOO THIN to be mechanically constrained along the filter / lens axis. Adding glue on the non-camera side appears to take up this gap, at least in the short term. I will search for some sort of spacer ring to use in place of the glue. Please do not ask for consultation on the repair process. I am not prepared to give this. The purpose of this review was simply to let people know that the Hoya filter glass fits in terms of diameter, but it is too thin in terms of thickness. This may help others plan, and hopefully improve, their own repairs.
