Can I use a Nikon 18-55mm f/3.5-4.5 for wide angle photography?

Can I use a Nikon 18-55mm f/3.5-4.5 for wide angle photography?

18mm is wide angle. So yes

Sure

Have you looked though the lens at 18 mm?

There's a much wider angle lens, the Nikkor 10-24 mm, which is super wide.

Here is a link that will show you what different focal lengths "see".

Yes, you can. 18mm is your widest. So you can use that end of your zoom. If you want something wider than that, then of course, you'll need to invest some more.
