Nikon Camera Lens’s, help picking.. tips.?
I currently have the Nikon – Zoom-Nikkor 18-55mm f/3.5-5.6 ED-II zoom lens.
I want to be able to zoom in farther with a new lens, but not sure which would be the next best and cheapest lens. Any tips.?
50-300mm.?
80-200mm.?
The new Nikkor 55-300 mm will give you some good reach.
Visit your local camera store and try it out.
300 mm is usually long enough for shooting outdoor sports, action and some wildlife.
Once you reach 400 mm or longer, you are looking at from $5,000 to nearly $10,000
