With the release of the Kolari R Drop-In Filters for EF-EOS R Lens Adapter and the Kolari R Magnetic Clip-In Filters, the options available to Canon mirrorless shooters can be a little overwhelming. Between the many infrared and general photography filters available in lens, drop-in, and clip-in varieties, there’s a lot to choose from. But not every filter is compatible with every camera. If you use a Canon R-series camera, modified for infrared or not, this tool will help you determine which filters are compatible with your sensor plus stacking options across the different filtering systems.
