This specimen was made in the 1970s in M43 screwmount. By the time I bought it, in the early 2000s, it had been converted to Pentax K mount, probably by gluing on an adapter. Stop-down metering only, on PK or M43 mount. Take $20 off the lens price if you promise to post images on mu-43.com within 90 days. Take $30 off the lens price if you promise to post images on mu-43 comparing this lens's results with those of the Panasonic 20/1.7 or Sigma 19/2.8. Price includes USPS insured shipping and regular PayPal. The following accessories can be bundled with the lens (but not bought separately): The RainbowImaging PK-to-M43 adapter mates perfectly with the lens and G3 body. The Heliopan 67mm multicoated slim UV filter that normally sells new for $100+ new and $45 used. This is the filter pictured, which has been on the lens since I bought it. I haven't take the time to use this lens on my M43 body. It delivered superb, sharp results on my K-mount film bodies, with neutral or understated colors, moderate contrast, and acceptably low distortion. but that was 10 years ago. The glass still looks clean, and the aperture ring turns crisply, without binding. But if you'd rather not take a chance, don't pay me till you've received the lens and tried it for 2 weeks. If you don't like it, return it to me insured and PayPal me $20 for taking the trouble and the risk. Here are four cell-phone shots of the CZJ 20/2.8 mounted to my Panasonic G3.
