Your camera won't allow you
to develop clear, crisp photos if your camera lens is
damaged or dirty. You can protect your thousand dollar lens
with a $20 filter if you use a UV or haze filter. These thin
glass filters are designed to screw onto the end of your
camera lens and you can just leave them on to protect your
lens. UV filters can help protect your lenses from dust,
moisture and scratches. If your lens is damaged it could
cost you quite a bit to repair or replace it. The filters
can also give you added benefits of correction for
Ultraviolet light which can show on your film as a bluish
cast and can sometimes distort distant details. UV filters
let you correct for the UV effect to varying degrees. They
are also useful if you are shooting mountain and marine
scenes, as the haze could affect the color and clarity of
the photos. UV filters can be bought for about $20.
Haze Filters Haze Filters
do just what they sound like, they filter out haze which is
created by minute particles of vapor and dust. Haze settles
in the atmosphere and can affect distant photographic
scenes. Haze forms when sunlight is scattered by minute
particles of matter that exist in the air. Atmospheric
conditions have an effect on the amount of haze in the air.
Mist, fog, smog, smoke and clouds are all different than
haze. Green and red light are scattered by haze, but not as
much as ultraviolet radiation, violet and blue light. If you
use filters to absorb scattered sunlight you can penetrate
the haze. Any filter that can absorb scattered sunlight can
be considered a haze filter.
Leica Ultraviolet (UVa) Filter. The Leica UVa Glass Filter is a wise initial investment. It helps protect your valuable investment from dust, moisture and scratches, which can lead to costly repairs.
UV filters provide additional benefits of correction for Ultraviolet(UV)
light, which can register on film and videotape as a bluish
cast, and can obscure distant details If desired, they can
be left on the lens at all times for protection
Ultraviolet filters allow you to correct for the UV effect
to varying degrees
UVA/IR. The Leica E39 UVA/IR Glass Filter (Silver
or Black) is specifically recommended for the Leica Digital M8 camera. In order to maintain maximum optical clarity, the M8with its superior sensorwas not designed with a total IR protection filter system.
This filter is designed to eliminate the pinkish/purple/reddish tint that certain black synthetic items might be subjected to when shooting under certain lighting conditions, such as incandescent bulbs. This filter can also serve to help protect the glass in your lens.
Note! Leica recommends removing the attached UV/IR filters when using lenses from 16-50mm in analog photography
Infrared filter for the M8 camera which does not have a built-in complete infrared system
Helps minimize potential pinkish tint under cetain conditions; ensures neutral color
No light loss
Can also serve as protective filter
Should only be used with 6-bit coded Leica lenses.
Leica Infrared (Black). The Leica UVA/Infrared filter is targeted for the M8 series camera. Although not a traditional infrared filter in the classic sense, i.e., helping with special effects images, this filter corrects for the magenta cast occasionally found on digital sensors.
This filter does not block by means of absorption, but rather by interference of the unwanted UV and IR
radiation that is repeatedly reflected between these layers,
affecting wavelengths on both sides of the visible spectrum
with a steep cut-off.
Leica 1x ND Filter. Neutral Density filters have several uses and offer the possibility to achieve otherwise unachievable results. ND filters appear grey and reduce the amount of light reaching the film. They have no effect on color balance. They have four main uses: 1) To enable slow shutter speeds to be used, especially with high speed films, to record movement in subjects such as waterfalls, clouds, or cars. 2) To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background. 3) To decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situations. 4) To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure.
Neutral Density factors:
ND.3 (exposure adjustment = 1 stop, reduces ISO 1/2)
ND.6 (exposure adjustment = 2 stops, reduces ISO 1/4)
ND.9 (exposure adjustment = 3 stops, reduces ISO 1/8)

These filters are used to reduce or eliminate reflections. They are ideal for photographing through glass or water as the glare from water tends to be white. Polarizing filters can also reduce the effects of haze and darken the blue sky image in black and white and color photography. There are various polarizing filters available to increase color saturation in a photo without altering the hues of image colors, but there are only two principal styles. One style fits over your camera lens, while the other is made to be used over the source of light. They don't affect color, that's why polarizing filters and screens are used in both black and white and color photography. There are two pieces to a polarizer. The front part rotates so you can change the angle of polarization. If you look at the blue sky through a polarizer and rotate it, the sky appears to get darker and then lighter. These filters range in price from about $15 to $800. They come in various sizes.
Leica Circular Polarizer (rotating Mount).
Creates dramatic sky/cloud contrast. Saturates colors
without changing color balance. Mount rotates to control
amount of effect. Increases contrast equally well with black
& white film.
Leica Circular Polarizer (Series 8). Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun. Filter factor is between 2.3 and 2.8 (approx. +1.3 stops).
Leica Linear Polarizer. Other than in an SLR, where the user sees his subject looking through the lens, the effect of a polarizing filter cannot be judged in the viewfinder of a rangefinder camera. Nevertheless, many users of rangefinder cameras would like to benefit from the photographic advantages of a polarizing filter, such as higher color saturation and reduction of reflections at non-metallic surfaces. A very easy-to-handle universal polarizing filter solves this problem for LEICA M-photographers.
A hinge allows it to be swung exactly 180° over the viewfinder for composition and setting, and back again over the lens for metering and shooting. The two special adapters (threaded rings) for the filter sizes E 39 and E 46 delivered with the filter enable the use of the majority of the present interchangeable lenses for the LEICA
M6-models; others for earlier lenses are also available. The
new universal polarizing filter replaces the former
polarizing filter A42.
Square & rectangle sizes are 75x75mm 100x100mm with the graduated.

Look at the front of your lens to find the size. If you have lenses of several
sizes, its a good idea get a 77mm or 72mm filter and get a step-up ring (lens to
filter size) for each of your lenses. That way, one filter will fit all your
