Use an adapter to mount these lenses to many mirrorless cameras.
Data credit: these ratings come from the remarkable research at irlensdb.com, a community-built resource that has tested and documented more infrared lenses than any other reference online. I have stripped the retailer links and reformatted the data, but the hard work of collecting it belongs to them.
Ratings describe how a lens behaves on an infrared-converted camera. A maybe lens is usually fine wide open and shows a hot spot as you stop down, so check the notes before you write one off.

Where this data comes from
These ratings are compiled from the community-maintained Infrared Lens Database, with contributor credits kept in the notes. Ratings are submitted by photographers using different conversions, so results vary by wavelength, aperture and individual lens copy — treat them as a strong starting point, not a guarantee. Retailer links from the source have been removed. If you have tested a lens, contribute your result back to the original database so everyone benefits.
