Have tested a Underground MC 28mm f/2.8 which has Pentax K (PK) mount.
Below are some of the test shots taken with this lens.
The B&W pictures are analog and are taken with a Chinon CG-5, AGFA CINEREX (X-ray film) and developed in X-tol.
Color shots are digital and are taken with a Canon 500D with lens mount adapter.
My review has more and hires images and can be found here if you're interested: http://blog.bkspicture.com/review_Un...28mm_f2.8.html
