dust in viewfinder v. affecting focus
In reply to Schwany, Oct 18, 2013

To press on the service advisory issue some more: I'm trying to figure out if there are different kinds of problems that could result from the "wear caused by insufficient lubrication":

The service advisory mentions two problems

1. AF searches but does not lock in on the subject.
(Caused by minute particles produced by wear mentioned above.)
2. The image shown in the viewfinder is “blurry” or “not steady”.
(Occurs if wear progresses.)

Presumably the viewfinder dust is due to wear caused by insufficient lubrication (or is this assumption incorrect?).

Assuming that this presumption is correct: does wear leading to dust viewfinder dust invariably lead to subsequent autofocus problems? Are the two closely tied together?
