A great tool in the hands of a master creates a work of art. A great tool in the hands of an idiot creates junks. A master knows his tools and they free him to concentrate on his craft. A mediocre partitioner plays with his amazing tools, admires it and even worships it but will never work hard to hone his skill. He will never become a master. Everyone will forget the chiesel that created the statue of David, or the paint brush that painted the ceiling of Sinstine chapel, But no one will forget Michelangelo and his creations. A true master may be excited about his tool and even praise it, but the reason for his excitement is that of the anticipation of the art that he will create. Nikon and Canon are both great tools, but where is the master of the craft?
