I found the strap that comes standard on the small side anyway so I replaced it immediately for a 'Sun Sniper'

Dear Pentax users

I want to buy the 'Sigma 18-125mm F/3.8-5.6 DC OS HSM Pentax' for my K-5, but is the Sigma's HSM motor compatible with the K-5 or is the K-5's screwdrive-motor compatible with Sigma's HSM?

I can only find old posts related to the K-7 and Sigma lenses!

Best regards,
Egon
