I still have it, the 18-55 Nikkor that come with the D50.
That lens isn't bad at all, sometimes you can notice it's not a piece of expensive lens, but not that often, and it's pretty sharpif you use it for subjects that it is easy to focus on.
EDIT: yeah, the rotating front element is iritating at time, forgot about that.
I'd like to replace it with either a 17-50 F2.8 Tamron or Sigma 18-50 mm F2.8 or the 17-70 mm Sigma.
Although I'll probably get both eventually, unless I get one of those F1.8 or F1.4 primes.
