Hi All,

Just an update - received lens back from the retailer yesterday. It had to go off to Pentax in Hamburg for a service and a replacement PCB. Well, what a huge improvement! Now focuses just as fast at 17mm as it does at 70mm. Additionally, it seems to be focusing very accurately too - no evidence of front or back focus so I am very pleased with it now.

Good job Pentax.
