This is the first and oldest generation of the now legendary Zeiss “Super Speed" lenses, commonly referred to as “B-Speeds.” Introduced in the 1970s this original housings has ARRI Bayonet Mount and comes with the Arri Bayonet to Arri PL so you can use this lens on any modern (or Vintage) cinema camera. They share a lot of DNA with the later versions of Super Speeds. Their incredible optics are made of “rare earth element glass,” (which lens manufacturers are no longer allowed to use). This 50mm B-Speed has its original coatings intact, and arguably most important its original iris design.
The thing that sets B-Speeds apart from nearly any other lens ever made is their unique 9-blade iris that results in an aperture that has the shape of a triangle with rounded sides. This iris design not only gives the lenses a more gentle focus roll off, but it also produces one of the most striking bokeh effects of any other lens. Shoot them wide open out-of-focus pinpoint light sources are rendered as round orbs. However stop down to T2, and the circular orbs turn into rounded triangles. B-Speeds give you multiple looks within the same set, and the ability to make your project stand out.
Breathing is minimal. Flares are very nice thanks to the vintage coatings. Shooting wide open results in a beautiful flattering look with a slight glow to highlights. Stop down and the look is sharper and has more contrast.
