I have had the D40 a little more than a month & as a beginner (new to DSLR) like it very much! It comes standard with an 18-55 lens. The guy at (a will refrain from naming) a very popular camera store had sold me a 55-200 lens telling me it is the ONLY other lens that works with this camera. I found out that Nikon makes a 18-200 lens. My question? Another photo store has told me that it will work on the D40. Is this true & if so is it a good lens to work with??? My thoughts are if it works good, I would have no need to change lens when I needed to.. Thanks!
