Hi all,
Despite being extremely happy with the optical performance now-a word of warning!
after just 4 weeks use where the lens has NOT been off the camera there seems to be
quite a lot of dust collecting inside the lens.I know there was a problem with the Canon 100-400 regarding dust in the past and was wondering if anyone else has noticed this or whether its just a problem with my copy?
Definately wasnt there 4 weeks ago when new.
