Photographers of Foo! Need your help on finding a lens.
So, I'm looking to get a lens for my Nikon D3100 for portraits and night shots. I was told by a friend this evening while at the pool hall that he knew someone who was looking for a photographer to come to his night club on Friday and Saturday nights to take photos of the club goers. I would also get paid for it! Well, it sounds like a lot of fun. I would be able to dress up, socialize, have a good time, and take some pictures. :D Problem is this: I feel as though my stock lens that came with the Nikon D3100 is sufficient for the task at hand.
After doing some research I noted the following lenses:
Nikkor 35 f1.8 DX
Nikkor 50 f1.4G
Any recommendations? Either way I would like to get a lens that would allow me to take photos at a rather close range (ie. flowers). I understand for that I'm going to need a macro lens.
