Looking for a Canon 28-135 IS lens. If you have a reasonably priced one you would like to sell please let me know. Would prefer that its not a refurbished unit but either one thats been lovingly owned and in Excellent condition (no scratches/dust etc) or about as near to new as possible. Been eyeing a few on ebay but would prefer to get it from a reputable person and not just a store if that makes sense?? Thanks.
