These questions don't go to the company employees, but to other Google Maps users like you. However I did go there recently and they do work on a Nikon equipment so the best thing would be to give them a call and ask about your specific lens issue.
We can take a look for you for $20. Once our tech has taken a look we will let you know of the cost. We are open from 10AM-5:30PM. We will be closed for a full week starting September 3rd and will return on September 10th.
