|Curiously enough, I catch new (old) projection glass towards the New Year, so that my posts here are systematically marked with swirl in this period. This time it is a Kern Paillard 1.6/50 for 16mm film projector. The lens physical form is pretty attractive, with its clean shape chrome barrel.
The lens vignettes and swirls on APS-C which makes part of its character, common to many 16mm projector lenses. As compared to many from this family, corner abberations are milder and central sharpness/punch is notorious. The barrel may be unscrewed in two parts giving an easy access to the glass for cleaning. If I got it right, the lens is a triplet, the barrel holding one small rear glass and two front ones (possibly a doublet).
The compact lens' size is a relative disadvantage in terms of adaptation, but I found a trick putting the lens into a section of M42 extension tube, with a poliprene padding fixing it inside, and attached the construction to an M42 helicoid. The resulting articulation is well tight and easily operative, giving the MFD of around 30cm.
Some quick shots taken with Sony Nex, with autocontrast applied.
