Kase Magnetic Circular Filters

The Kase Magnetic Circular Filters are made from the same tough, colour neutral pro glass as our square filters, so you can be assured of your image quality and still have peace of mind whatever the conditions.

These filters are perfect for those that do not require a full square system setup, the advantage being that they are lighter and more compact, making them a great companion to have in your camera bag. The sets consist of stackable neutral density filters and a CPL, useful for both photographers and videographers, allowing you to both control reflections and control light.

1. Review your lens threads and focal lengths – Select the largest lens thread size

Whatever your largest thread size is, go up to the next size. This will prevent vignetting when stacking on wide angle lens.

Example, 24-70mm f/4 lens (72mm thread) = 77mm Circular Filters.
24-70mm f/4 (72mm thread) and 14-30mm f/4 (82mm thread) = 95mm Circular filters plus 72-95mm and 82-95mm magnetic adapters.

Kase Revolution Magnetic Circular Filters, the next generation…

Incorporating the much loved and trusted Wolverine glass, known for its clarity, toughness, and excellent colour control, the Revolution filters take it to the next level on ease of use. Coloured Identifying rings make it easier to select the filters you need, new adaptor rings help reduce vignetting on those awkward lenses. Identify each filter with confidence and select the right tool for the job, allowing you to focus more time on photography. 

The new Wolverine Magnetic Circular Revolution filters are backwards compatible* with existing Kase Magnetic Circular filters, magnetic circular adapters, step-up rings and the magnetic lens hoods. Allowing you to continue to use our rich and diverse filter ecosystem. Whether you are new to filters or a long-term user of Kase filters. 

For many users, all circular filters were not an option and had some limitations due to some lens constructions. Which prevented circular filters being stacked and would cause vignetting regardless of the size used. 

Kase filters have resolved this by introducing an inlaid adapter ring which fits inside the lens thread, meaning the filters sit closer to the lens element and ultimately reduces vignetting. This adapter, comes as standard with all kits. Available in 77mm and 82mm Entry and Pro kits only at launch. More sizes available soon.

*Kase Revolution filters will attach to existing Kase Wolverine Circular Filters and adaptors and accessories.

The Kase Wolverine Magnetic Circular Filters

Things to consider when using the Kase Wolverine Magnetic Circular filters.

Stacking filters will increase the chance of vignetting on wide angle lenses. One way to negate this is to buy a bigger size than you need and use our magnetic step up rings. Another point to consider is that using step up rings will mean that your lens hood can not be used at the same time as the filters.

Magnetic filters are not designed to be kept on your lens at all times. By making these filters so very easy to use and allowing you to swap them quickly and easily when taking a photo we think we have come up with a winner of a design. It would be remiss of us though not to point out that having the filters attached using a strong magnetic force is not as secure as screwing a filter to your lens. We do not recommend that you walk around with these attached to your camera lens all the times, we would hate you to accidentally lose them. 

3. Review remaining lens and select what adapters you need

Do you want to use the Magnetic Lens Hoods? If so, you will require standard (non-magnetic) step up rings. If you do not wish to use the Magnetic Lens Hoods, you can use our magnetic step-up rings.

The lens adaptors screw direct to your lens and are just one size to correspond with your kit, however if you need to step from a smaller lens thread size then our magnetic step rings work as both the lens adaptor and step ring.

Example, if you buy an 82mm set for your largest 77mm lens thread, you also want to use it on a 72mm lens thread, simply buy a 72-82mm magnetic step-up ring, this allows you to mount the magnetic circular filters directly to your 72mm lens thread.

If you buy an 82mm magnetic filter kit and 82mm magnetic lens hood to use on 72 and 77mm lens threads. You will require standard (non-magnetic) step-up rings 72-82 and 77-82mm with the 82mm lens hood adapters. This allows you to use the lens hoods across all your lens, with your magnetic circular filters.

Don’t forget to buy extra lens caps to fit your set size if you want to keep them on your lenses at all times.
