The real issues with the DX 18-200mm VR II that it has some distortion (mostly easy to correct in software) and that it's fairly slow (f/5.6 from about 100mm to 200mm) but both of those caveats are the price to be paid for a super zoom lens like this.Ok, now I'm really confused.Keeping in mind that I'm a complete camera and photography newbie, yes, I was actually looking at this 18-200 lens because it seemed so flexible.
As for what I want to shoot, maybe it's a lame answer, but well, everything. I want to do close-ups, far distances, stills, things in motion, day shots, and night shots. Is that vague enough?Oh and I really want to take some cool DOF pics, that's high on my list.
Is the 18-200 is a good newbie lens that will deliver reasonably good performance in most scenarios? My thinking was to get this one to start, and then once I've gained enough experience to appreciate the difference, to go and get some more special purpose lenses. Good idea, or no?
The big advantage is that, as a new dSLR user, you'll be able to learn a good bit about what focal lengths you are inclined to use and that you'll have a wide range to start with, and without having to change lenses. Though you'll probably find you take a lot of shots at 18mm and 200mm, at least at first. You can to back later and look at the EXIF data from your shots to see which focal lengths seem to get the most use -- and which ones tend to "work" for you.
IMO, you could do a lot worse than to start with the 18-200mm VR II and use that $250 rebate toward a faster prime like the 35mm f/2 or maybe the 35mm f/1.8 DX for low light/indoor shooting. And, if you decide to upgrade later, you'll be able to get a good chunk of the cost of those lenses back (which isn't as true for the camera body).
Good luck on whatever you decide.
