The first in a range of one-off ‘boutique’ lens sets. Truly unique in every way, and unlikely to be replicated by our many impersonators! Each of the four focal lengths in this lens set (28, 38, 58 and 88mm) contains a matched 1950’s Meyer Optik Primoplan with aperture of f/1.9. Capable of covering Alexa LF, Sony Venice, and RED VV in open gate, this is the first time a complete set of lenses based upon the Primoplan optical formula has been available for cinematographic purposes. The fragile single layer coatings are in near perfect condition. The external finish is an authentic oxidation process encapsulated under a durable ceramic impregnated polyurethane coating. Incorporated within each lens is an over-sized aperture iris, permitting light to hit unpolished optical edges and internal element seatings for unpredictable flaring when wide open, and more control of flares when closed down to match the true f/1.9 optical clear aperture. These lenses come without focus scales or aperture markings (to preserve the beauty of the external finish) however we can add markings if required.
