Modified old lenses

All the old fixed focal length lenses having been kept while the Silver Salt Film period have modified to adopt into Canon EOS Digital SLR body. Every camera company has developed many zoom lenses for the actual convenience in line with the times, but I insist on my own concept that I use only the fixed focal lenses which are so individual promptly. According to my experience, no variable focal length lens could not exceed the performance of fixed one however expensive it might be , this is why I follow my own way persistently. I'm going to enjoy like this my photographic life for the time being.
