ROUND KW Revolution Magnetic CPL polarizing filter

Our magnetic round filters from the KW Revolution series are made of the same tempered glass as our Wolverine rectangular filters and therefore have the same excellent imaging performance, extremely low color shift and high impact resistance. In photography, polarizing filters are often used to minimize light reflections or to increase the intensity of natural blue and green tones and also to increase the contrast range. Remove unwanted reflections and glare on surfaces such as glass or water with a turn of the CPL filter. This correction can usually no longer be implemented in post-processing due to the lack of image information. The magnetic polarization filter is supplied with a matching magnetic adapter ring, which can also be used with our magnetic ND filters with the same diameter./span> Frame material: Aluminum / magnetic strip Glass material: tempered optical glass Scope of delivery: 1x Round KW Revolution Magnetic CPL Polarizing Filter (Silver Frame) 1x magnetic adapter ring for screwing onto the lens 1x storage box

ARMOUR slide-in CPL polarising filter with rotating function

The special feature of our rotating insert polarising filter with rotating function is its mechanism, which allows the polarising filter to be rotated independently of the filter holder.This means that graduated filters or other ND filters, which are attached to the front of the filter holder via a magnetic frame, can be ideally combined with the freely rotatable polarising filter. In which cases is this required? Particularly wide-angle lenses such as the Sony 14mm F1.8, Laowa 15mm and the Olympus 7-14mm have a very strong curvature of the lens which generally makes it impossible to use a 100mm filter holder. To overcome this, we have developed special adapters which are used with our ARMOUR 100mm filter holder. This means that these ultra-wide-angle lenses can be used on a 100mm filter holder. However, as the magnetic 95mm polarising filter of the ARMOUR filter holder can no longer be used in this case, this insert polarising filter with rotatable polarising filter gives you back some flexibility. Scope of delivery: 1x ARMOUR insert polarising filter Note: This polarising filter is not as shock-resistant as the Wolverine series. This is due to the fact that the glass of a polarising filter (also the case with other manufacturers) cannot be thermally hardened accordingly.

Improving photos with polarizer camera filters

Circular Polarizer (CPL) filters reduce reflections and light reflections from non-metallic surfaces. They can significantly help to improve the quality of photos:

Reduce glare: CPL filters minimize reflections and glare from non-metallic surfaces, such as water and glass, for clearer and more detailed shots.
Enhanced colors: Polarizing lens filters can deepen the saturation of colors that are typically present in outdoor scenes, like blues in the sky and greens in foliage, making them more visually striking and true to life.
Improve contrast: This filter helps to cut atmospheric haze and enhance the overall image contrast, making the subjects stand out with greater definition. If a subject is at a 90° angle to the sun, a CPL filter can be used to enhance the blue of the sky.

FAQs about polarizer filters for camera lens

How does a CPL filter work?

The light can reflect off of objects and surfaces, as well as be absorbed by certain materials. As it travels through space, light waves oscillate in multiple planes. However, a CPL filter is designed to ensure that light waves only oscillate in one plane, which allows for improved clarity and reduced glare. Additionally, the direction and degree of polarization can be adjusted by rotating a polarizer lens filter.

How do I use a CPL lens filter?

Attach the polarizer filter onto the front of your camera lens: simply screw it in or attach to the adapter ring. Once attached, rotate the outer ring of the CPL filter to achieve the desired effect. If you are using one of our filter holders, rotate the corresponding wheel on the holder. Experiment with the rotation to minimize reflections and optimize color saturation based on your shooting conditions.

What size polarizer filter do I need for my camera lens?

To determine the correct size for your polarizer filter, check the diameter marked on your camera lens. It is usually imprinted near the front of the lens or mentioned in the lens specifications. Choose a CPL filter with the same diameter to ensure a proper fit. If you plan to use a polarizer filter on a camera lens of different diameters, take the filter matching the diameter of the biggest filter.

What types of polarizer filters exist?

At Kase, there are three types of polarizers for camera lens:

Screw-in CPL filters can be attached directly to the lens. These filters are ideal for handheld photography and can be easily rotated on the lens.
Round CPL filters which can be attached directly to the filter holder ring of the Kase filter system. Using an external wheel on the filter holder, you can rotate the filter.
Rectangular polarizer filters can be used with the filter holders and combined easily with several other filters.

Can you leave a polarizing filter on all the time?

While you can leave a polarizing filter on your camera lens, it's important to note that the filter may reduce the amount of light entering the lens, particularly when fully polarized. Consider removing the CPL filter in situations where maximum light intake is crucial in poorly lit environments. Otherwise, you can keep the CPL filter on to benefit from reduced glare and enhanced colors in various shooting scenarios whenever it´s the effect that you want to get.

How do I clean a polarizer filter?

For cleaning a polarizer camera filter, use an air blower or a soft brush to remove any loose particles. If smudges or fingerprints persist, use a microfiber cleaning cloth or cloth dampened in distilled water. It’s important to avoid using abrasive materials that could scratch the filter or chemicals since they can damage the filter.

Can I use CPL lens filters with other filters?

Absolutely. Some of the CPL filters are stackable, so you can get creative by combining them with other filters. It’s common to combine a polarizer with an ND filter for shooting water bodies. However, you can combine them with other filters as well.

Read our blog about stacking multiple filters.

Are CPL lens filters only for outdoor photography?

Not only! While polarizing filters are highly effective in landscape photography, they can also be used indoors to reduce reflections on glass surfaces or enhance colors in certain lighting conditions.
