Anyone living in Canada who needs lens repaired should get in touch with Ralph Innes, who is located on Vancouver Island in British Columbia, Canada. He does excellent work and the lenses come back renewed for another thirty to forty years of life. Ralph's web site describes how he got into the lens fixing business as a result of his love for Kiron lenses, which are notorious for grease breakdown jamming the apertures. Ralph recently fixed an Orestor lens for me, and he did an excellent job getting rid of the grease on the fifteen blade aperture. His rates are low, the quality of his work is high. Highly Recommended.
