Is it M42 or K-mount? Its a manual lens either way. Good lens even by today's standards. However the 4 optical elements give it a long minimum focus distance. Longer than a current lens like the AF Sigma 500/4.5 for instance that has more elements. These things tend to go for around $700-800 on eBay depending on version, whether it is SMC or not, or one of the ones with Nikon mounts modified in NYC for the AP. Nobody makes a 500/4.5 mirror lens by the way. Only Sigma made a 500/4 mirror which actually goes pretty high on the used market. Kent Gittings

This is the SMC, and is NOT a mirror lens. I've got the chance to get one, and am thinking about jumping on it as a holiday gift of sorts to myself . . .
