So sorry this happened to you. First, yes Precision camera. They have an online quote generator, but be sitting down when you get the result. I may call them today about something, a lens hood issue with my 31 ltd---it's loose, but the quote generator just spits out a number w/o regard to the problem, it seems. If you're in warranty, make haste, though!
Second, check that the Z still works with another lens. I fell off a 5 foot ladder and landed camera first(fortunately not lens first...). I was more hurt than the camera, they are pretty tough.
Third, there do exist
if you are OOW and don't like Precision's quote.
