It is in great condition and highly rated on many websites including PentaxForums:

The only problem with this great lens has to do with its large aperture flange (fits to many older Pentax cameras but not all Pentax DSLRs) but in my lens this problem has been resolved: flange was cut down and lens works perfectly on all Pentax cameras (K-5, K-7, K20D, K10D, K100D, K200D, K-r, K-x, etc.).
