Stumbled across Kolari while trying to learn about IR photography & I’m glad I did. Ilija did a 590nm conversion on my Canon S90 & it’s excellent. After the first week of testing, I haven’t yet managed to create the promised hotspots with this cam, though Ilija assures me I’ll eventually figure out how to combine the right set of conditions! He is a pleasure to work with, the service is excellent, great communications, prompt responses & delivery. And I couldn’t tell my camera had been opened. I will be sending my next camera to Kolari Vison for conversion & I was almost reluctant to write such a good (& honest) review in case he’s too overworked to do my next job!!!
