Norm, This is exactly what I was affraid of - the dust can escape from the lens and scatter all over my camera bag! If you feel you can tackle the problem I will gladly send you the lens safely packed along with SMC M 24-35/3.5, K 28/2 and K 35/2 which also have some dust inside. I am really glad you offered help as I was feeling somewhat lost not knowing what to do. Luckily FA 35/2 is new and therefore relatively clean.
Do you feel you could dispose also my refconverter A and a MX body? :-) Pawel Norm Baugher wrote: > Hi Pawel, sounds like a lot of dust.
