I'm feeling the need to rant about the Nikon Service department. A couple of months ago, I encountered the dreaded dust spot issue on my Nikon D70. I decided to send the camera in to Nikon Service for a sensor cleaning because I wasn't comfortable with doing this myself. Fifty dollars (this is not covered under the warranty) and 6 weeks later I get the camera back. I take some test photos... and discover that the dust spot problem just got worse!!! Are there any other Nikon owners out there who have had a similar problem with Nikon Service??? And for those of you who are digital SLR users who change lenses from time to time, have you ever experienced the dust spot issue?
