Hi Luigi do you happen to know whether there is a list somewhere with all that lenses from other manufactures that fit on a Pentax K camera like the SF7/SFX series . I'm not talking about OEM brands like sigma, Tamron, Tokina etc, but maybe Ricoh, Konica, Cosina and others?
For ex. the 50mm f/1.4 XR Rikenon you mentioned.. thanks Markus >>50mm f/1.4 XR Rikenon (I bought it because I couldn't afford a >>real Pentax-M >>or -A 50mm f/1.4 at the time). I am making it a bit of a hobby to find >>"good-enough" old lenses at decent prices.
