I'm wondering, what lens do you recommend for D7000 users, mate?
TIA
Depends on what type of shooting you want to do...Alden suggested an excellent lens (or lenses since he specified the D or G versions)above...I would always recommend going for the best glass you can get...my favorite would be the 70-200 f/2.8, but that might be overkill for some folks in terms of its range or its cost depending on what they were shooting...
Personally, I shoot sports - indoor and at night on lit fields - so I knew I would need the fastest, highest end lenses I could afford. I also planned to move to full frame even though I didn't have one at the time...those combined meant that I chose not to purchase any DX lenses and got me eventually into lenses like the 70-200 above. Your choices may be different than mine because of what you like to shoot and your reasons for shooting, but I doubt you can go wrong by picking the best lens you can afford for the photos you want to take (note that does NOT mean the most expensive!)...
