It's a rather new hobby for me. I've taken pictures before, but with crappy cameras. Seeing all the great photos here on Steem gave me the itch to finally get some decent gear.
As far as what lens you would need for night shots, I'm not the right person to answer that one. Someone like pfunk, jamtaylor or steemychicken1 may be able to help though. Make a post in #photography and I'm sure someone would be able to give you a rather precise answer.
