저는 AF Nikkor 80-200mm F2.8, Sigma 17-70m F2.8-4.5 이렇게 쓰고 있지요.
참 일전에 kiki님께서 하사하신 MF Nikkor 50mm F1.8도 잘쓰고 있구요.

60 mm micro f2.8
일할때 사용하는렌즈인데
가끔 심심풀이 접사놀이 할때 아주 좋답니다.

전 18-50(3.5-5.6인가) 하는 놈,
28-70(2.8)
85(1.8) 요놈만 니콘, 나머진 다 시그마
70-200(2.8)
그리고 2배 컨버터가 있는데... 거의 쓰진 않죠.

제가 듣기로는 싸구마 렌즈에도 니콘렌즈만큼 잘 나오는 화각이 있다던데... 그런정보를 어디서 얻어야할지..
참, 만능화각으로 토키나 17-50 2.8 도 괜찮아 보이더군요. 그거 펜탁스랑 제휴해서 만든거라던데...쩝

Depends on your budget and the angle you want to shoot. I've used Nikon for 5+ years, so I know the lenses left and right.

If the money is not an issue, you want to buy these lenses.

1. 17-35 2.8
2. 28-70
3. 70-200 VR
4. 85mm 1.4
5. 28mm 1.4
6. 45mm 2.8
7. 105mm 2.0 DC
8. 135mm 2.0 DC
9. 180mm 2.8
10. 200mm 4.0 Macro

If the budget is an issue, then..

18-35mm
50mm 1.8
85 1.8
80-200 2.8

I'd avoid any lenses that covers an extreme angle. But then, that's just me.

12-24mm is also very nice lens.

budget DEFINITELY is an issue!!! hahaha....T.T
that is why i'm planning on buying a 50mm 1.4. would you say 85mm is better than 50mm??

50mm produces rather dull photos, but it's very good lens to start out with. If you are starting out, then I'd go with 50mm 1.8 then see if this is your primary angle. If it is, it's not too late to sell your old 50mm 1.8 and get a 50mm 1.4. Optically, they both produce very good pictures.

I think most people do not know what angle they shoot most. Once you shoot a lot, you started to get a feel for an angle that you usually shoot with. Then, investing a good lens in that angle is a good idea. I'd avoid buying any lens with top quality when you find yourself not using at all or rarely.

So in short, why not buy 50mm 1.8 first and see how it is? Then you can either replace it with 50mm 1.4 or buy additional 85mm 1.8.
