. I just purchased a D700 to help out my wedding business and to help on those highschool sports. What I am wondering is ... can I use my lenses that I already have for my d80 for the d700 without losing any quality on pixels or anything else for that matter? I have 3 lenses that I am pretty fond of: 1. Nikkor 50mm 1.8D 2. Tamron 28-75mm 2.8 xr di ld 3. Nikkor 70-300mm 4.5-5.6 g af-s vr Do I need to buy all new glass for my new d700? And I got a great deal on my d700..im stoked... got it for $2100 from a family member that owns a store -Puma- .
