I have a Nikon D70 and love it. I have only the lens that came with the camera (AF-S Nikkor 18-70mm). What would be a good 2nd lens for this camera? I shot pictures of a
B-17 taking off today, and the image looks more like a chicken hawk (very small image). What is the next logical step up in magnification in a digital lens for this camera? Any thoughts on this?
