Very nice external condition. 2 small marks on front element which will not affect image quality.
Most sought after manual lens. Often used for technical purposes due to exceptional sharpness (eg. spectroscopy use which one commercial client puts the lenses to). Compact design focus on quality and no allowances made as to costs (before all prices were raised dramatically following sterling’s collapse these were retailing for £560 equivalent to some £900 today). Long “throw” on helicoid allows for pinpoint accurate and smooth focus.
