Wow - it's almost like we dealt with different repair companies! I sent my 16-50 lens off for repair in early December. After three months of them not answering the phone and not responding to emails, I decided to try working through Pentax support, figuring they might have some pull with the jokers at Precision Camera. Two days after contacting Pentax, I received an email from Pentax telling me that my lens had been shipped to me via UPS that morning. I heard nothing from Precision Camera, and of course they didn't bother to send a tracking number. I really have no idea if it is actually on the way or when it will arrive. And, I have no idea if they actually did the repair, another common problem with Precision Camera. All I can do is wait and see.
Really, avoid Precision Camera if you can. Their customer service is non-existent. They don't answer the phone. They don't respond to emails. If you keep trying on a daily basis, and if you do it for a couple of weeks, you *might* eventually get someone on the phone, but even then, they don't follow through on their promises. It has been an awful and frustrating experience.
If you want another data point, check out the Yelp reviews -
Precision Camera - Photography Stores & Services - Enfield, CT - Yelp . Just about every review past 2010 is a 1 star review. There are a couple of 5 star reviews, but they are definitely the exception.
My advice - take your repair business elsewhere - anywhere else, just don't use Precision Camera.
