Seriously - I've been learning about something very interesting lately, though. I've been learning about the 'M42 screwmount'. I'm referring to the mounts on Pentax, Praktica, Pentacon, Icarex TM, Chinon, Cosina, Ricoh, Fujica, Mamiya, Yashica, Hanimex, Edixa, Petri, Zenit, Carena and others. Appearently there are some world class lenses available with this mount - most notably Zeiss, and Fujinon EBC. Now I've heard that the Super-Takumars were excellent, too. ..And now I hear about Rork's Zenitar 16mm 2.8 MC fisheye! I am seriously thinking about switching to a screwmount body. Joe
