NPS 400mm f5.9 for M42 brand_Really Right Stuff slight internal haze- nothing dramaticThis is a simple (but large) telephoto lens for the M42 thread mount. In the old tradition of simple telephoto lenses, close focusing distance is 18 feet, and best performance will not be had at f5. 9. But, theres a tripod mounting collar, the glass is clean, and focusing is smooth. The mount is even interchangeable (its a T mount)
