Zeiss Super Speeds Mk I, or B-speeds were some of the fastest lenses when they first came out in the 70s. The Lenses have been full serviced and remounted for PL mount cameras. The front on the lenses have been spaced out to 80mm diameter.

Front Diameter	Aperture	Close Focus	Front Diameter
25mm	T1.4 – T22	250mm – 10′	80mm
35mm	T1.4 – T22	355mm – 14″	80mm
50mm	T1.4 – T22	406mm – 16″	80mm
80mm	T1.4 – T22	609mm – 24″	80mm

These lenses have their original glass, original coating (giving very nice flares), and iris.

With their iconic 9-Blade iris, these lenses have a distinct rounded corner triangle shaped aperture. That means when shooting stopped down, out of focus points of light have a iconic triangular shaped bokeh. This does not occur when shooting wide open. The iris also gives a more gentle focus roll off.

These lenses are very delicate. With rear elements being exposed on some lenses. Extra care is needed for use.

Lenses used on such iconic movies asTaxi Driver (1976), Raging Bull (1980), The Shining (1980).
