I have a Nikon D-70 with the following lenses: 18-70 Nikon 'kit lens' 105 mm macro Nikon(non vr) 70-300 4-5.6 Nikon(cheapo lens) decent pictures, but would like longer lens at times. Have saved some money and want to purchase a new lens. Two thoughts, 70-200mm f2.8 vr, not really long enough (for wildlife etc), but fast and good all around so would probably get a 2x converter. If I get this lens, would there be any reason to keep the 105mm (non vr) macro? or 80-400mm f4.5-5.6 vr not as fast (reviews also say slow focusing) but quite a bit cheaper, especially since I won't need 2x converter. Looked at 400mm prime lens, but price is out of my range. Any thoughts/feedback greatly appreciated............. Dave M.
