Heliopan 40.5mm Linear Polarizer Filter
Key Features
- Minimize Reflections and Glare
- Reduces Haze and Blue Cast in Landscapes
- Enhances Color and Tonal Saturation
- 40.5mm Front Filter Threads
The Heliopan 40.5mm Linear Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A linear polarizer differs from a circular polarizer in that it does not supports 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.

With a mirrorless Micro-4/3rds camera, do you need to use a circular polarizer? Or will a linear one be effective?
Circular polarizer filters are recommended for use if you will be using autofocus to focus your lens, as linearly-polarized light can confuse autofocus sensors and cause autofocus errors. However, if you will be focusing your lens manually, you may use a linear polarizing filter.

Thickness? Need 30.5 mm polarizer that will fit ...
Thickness? Need 30.5 mm polarizer that will fit in filter drawer of 600 mm catadioptric. Filter needs to be 7 mm thick.
I purchased one through Amazon, turned out to be the same thing, Heliopan #730539. Fits the 30.5mm thread in the filter tray ok, but the thickness is 8 mm, so doesn't work. It is 6 mm from outer edge of one knurled ring to the outer edge of the other. This is the rotating part. The mounting threads are 2 mm deep, so overall width is 8 mm.

I have a Nikon Coolpix L340. I am aware that it's lens is 35mm. Is this polarizer applicable to that particular camera?
The Nikon COOLPIX L340 digital camera does not have filter threads on the lens. So you cannot use any filters on this camera.
