Im a complete amateur at photography. I recently bought a Nikon d3200 SLR with the 18-55mm lens kit. I've bought it specifically for my trip to Lapland to hopefully see the northern lights. Could someone please advise me on what lens would be best based on a low end budget?
The lens is fine; you'll probably want to mostly use the wide end of the zoom range. What you really need is a tripod, since the exposure time will be on the order of seconds. With a "fast" lens (which the 18-55 unfortunately isn't), you could be able to grab handheld photos of especially bright auroras, but to get the sort of "amazing" shots you see on the Internet, you're going to need a tripod.
