It doesn't work with the K100D or K200D.

Also look at the Metz 48 AF-1 -- considerably cheaper than the Metz 58 AF-1. I have one and it works great with P-TTL, both on-camera and controlled as a wireless slave.

Thank you very much.

The SIGMA seems to have a mind on its own, yesterday it worked on wireless P TTL mode on the K10D.

Metz 48 AF-1 is not available here, but 58 AF-1 is available. But this does not have the P/S Suffix meaning this may not work with Pentax cameras. The dealer claimed that this will work with the Pentax K10D, but the Metz website clearly says that only the Metz 58 AF-I P / S will work with K10D.

Thanks for your reply while I am trying to get the 48 AF-1 or the 58 AF-1 P/S.

Best Regards,
