As for your question I have contemplated this issue. My replacement values range a fair amount but I have nothing over 500,000 and only one over 300,000. With frame rate on my newer camera I suspect I will achieve those values in record time.


As for my Digital cameras they would just fail and typically fairly
hard and nothing to do with the actuator. I am not sure if the years of bumps just took their toll but I
just replaced them rather than suffering the down time while they get repaired.
