Canon TS-E 17mm f4 Teleconverter and the focusing isn't theThe Canon TS E 17mm f4 is a full frame ultra wide angle lens with tilt & shift capability, making it ideal for tight interiors and close range architectural shooting. Cosmetic condition is not superb, with paint wear and a few scuffs and scrapes. However, function is excellent, and optics are clean, with minor dust. It's a "user", as they say. Includes front and rear caps. Please note: this is a manual focus lens.
