I have a fairly new FE 100-400 G Master and although the lens is sharp, a huge annoyance with the lens is the amount of zoom creep when at the tight setting.
This seems to be a general problem with most owners with active threads in Fred Miranda and DPReview.
Even when the lens arrives with the tight setting holding the lens in position, light useage causes this to loosen to the point that the tight setting no longer works.
One owner has found it so bad he can't rely on long exposures with the lens elevated slightly.
Ive owned the canon equivalent and never had a problem with this at the tight setting.
Has anyone had any experience getting Sony to address this as a defect?
