Currently I have the Nikon 55-300mm f/4.5-5.6 VR for DX camera. It has been a great lens in general, and I love the 300mm capacity. The 70-300mm VR has many good reviews, despite some discussion of soft focus when it is used close to 300mm. To me it sounds like an upgrade, since it has IF and VR II. (Cannot afford the new 80-400mm right now, although that would be an even better choice.)
Opinions appreciated on whether this is a truly an upgrade for me.
Also, how will it affect my long-distance photography (nature, wildlife). I have not got a good understanding of what it means when Nikon states " 300mm of telephoto reach (450mm equivalent on DX-format D-SLRs)". I mean, 300mm is 300mm. My suspicion is that this is a perceptual thing rather than actual. Please enlighten me.
The price in the Nikon Store Outlet is $269.96 for a refurbished lens. My thought is that the possibility of the problems I have read about is decreased because it went through the "refurbish" process.
I could sell my 55-300mm to pay for part of the cost.
Thanks for your insights.
