I sent my Lumix G5 in to Kolarivision for 590nm conversion. I receieved the camera back in less than 10 days. I have been very pleased with the results! Focus with my 9-18mm Olympus lens is excellent, and manual focus with my 7.5mm Rokinon is easy. Images exhibit good sharpness. I had Canon 40D previously that was converted by a competitor at a much higher cost, and the Kolarivision conversion is every bit as good if not better. Kolarivision will definitely be my choice for any future conversions.
