I wrote a little article for NYIP about bargain lenses:
Beyond Your Kit Lens:
Cheap -- But Good -- Lenses for your Digital SLR
"Most people who buy a Digital Single Lens Reflex (DSLR) camera purchase the lens bundled with the camera -- the "kit lens" -- and do just fine. After a little shooting, though, they realize there's a world of possibility out there for their photography if they add a few new lenses. That's what an SLR camera allows you to do -- take that kit lens off and put other lenses on. At this point, however, sticker shock can set in: the best-rated lenses often come with a very big price tag.
So, are there some great bargains out there? Can you start adding to your camera bag without breaking the bank? Could we assemble a full camera bag of high-quality, useful lenses for under $1000? It turns out that we can."
