LUG - I finally heard back from the SL specialist at Leica. He suggested I try to gently wiggle the front element of the lens. That worked!! It is now moving smoothly from 24-90. Thanks for your suggestions, everybody! Tina -Tina Manley www.tinamanley.com tina-manley.artistwebsites.com http://www.alamy.com/stock-photography/3B49552F-90A0-4D0A-A11D-2175C937AA91/Tina+Manley.html
