Hi everyone! So I just got 2 used Nikon cameras, a D50 and a D70s. I have a small room that is my recording studio (10' x 8') and I would like to use the D50 to take some nice pictures of my guests. Right now I have a Nikon AF Nikkor 50mm 1:1.8 D and I can't seem to fit few people inside my studio in the picture. So for a very small room, the lighting is poor what would be the best lens to buy as I don't have a lof of money to spend, if possible around $100. I am not looking to buy a new lens I can settle for a use one that would do the job. Can I use a macro lens with my current lens? Also, what would be a good lens for taking pictures of birds and trees, as my girlfriend likes to take that kind of pictures with the D70s. Thank you in advance.
