Hi, I have the opportunity to get a Nikon 80-400mm f/4.5-5.6D ED VR. I'm new to DSLR, I just got a D7k with a 18-105 kit and I sure find myself missing a lot of shots because the lack of reach. I'm not really a nature man but I do trips with my family and I'm starting a collection of my daughters favorite animals, views, etc. (...and eventually would like sell them when a worthy one comes). Thing is, I've read this is not a very updated lens, and not fast enough for some situations (I don't do sports). Do you think it is worth the investment or should I go for a 70-300 instead? (I mean, there is almost a 1k of difference in price). I've read posts saying that maybe nikon would update the 80-400. I'm talking about new lenses. I wouldn't like to venture on used ones while I can't recognize good from bad. Any advice? Thanks. klv.
