Yep, the 17-35 is a really good quality lens and never fails to produce crisp images. What I like about it most (apart from fabulous image quality) is how smoothly the telephoto slides. The 18-70 is cheaply built, and the telephoto operation seems to "clunk" a lot and focus takes time to "kick in" for some reason. I just don't like the lens. The 17-35 has it all over the 18-70.
So far, nothing I have tried has the 80-200 beat for price and quality! Its a spectacular lens!
They are great people! I once had a problem and only 15 minutes to find the answer. I couldn't find it in the booklet so quickly asked on Nikonians. (I was at a music festival and didn't want to miss a shot of the headliners)
They came through in the nick of time and I got some great shots! They are a wonderful bunch of folks. Very knowledgeable and great even with newbies and total greenhorns.
