KMZ Zenitar-M2s 50mm f/2 MC MOD - M42

Modified M42 normal lens for experimental photography. Modification affects lens rendering radically, adds heaps of aberrations and makes the bokeh extra-swirly. Modified lens is only suitable for close-up photography. See sample photo for reference . Aperture has been modified for manual operation, so works great with an adapter. Optics are tidy.
