Ok so i am looking at getting a new lens for macro photography and im wondering how much of a difference i will notice
currently i have a
- 18-70mm Nikon DX (focus up to 1.3ft)
- 70-300mm Nikon D (focus up to 5ft)
but keep in mind since it is on a digital camera it is really a 105-450mm and that brings things darn close at 5ft away

here are the 2 lenses i am looking at
Nikon 105mm/2.8 AF MICRO D

Nikon 60mm/2.8 AF MICRO D

So if i could get some feed back on if you all think this is worth it or not, it would be very appreiated
