I purchased the Canon EOS M with a 720nm filter conversion from Kolari in July 2015. It is a nice compact user friendly mirrorless camera and I was able to find a lens adapter for using all of the Canon EF-S mount lenses. The Kolari website has a very informative tutorial section where they explain the use of the GIMP photo processing method. I downloaded the GIMP application and it is working rather well. The Kolari product is first class.
