I just got my D700 body back from Nikon on friday and as luck would have it my 28-70mm f2.8 lens aperture mechanism died on the weekend. So back off to Nikon I went. I bought the lens back in 2007 so it should still be under warranty. This is a good thing as money is pretty tight right now. At least until I start getting paid from the last few gigs.
It's times like this where I'm glad I have a zipcar. Taking transit to get to Nikon would take 3 hours each way and taking a cab would be easily $120 for the round trip. With Zipcar it's only $26.00 and it still gives me time to do grocery shopping.
