To answer the OP, I have been into photography for quite some time. For Christmas I received a Canon 7D, and I've really been enjoying the shots I get with it. I don't use it on the farm, simply because my goats and horses are far too friendly and they have a tendency to be a little rough. On the farm I use my trusty 'ole Canon T1I!
I also have a collection of lenses that includes a 50mm f/1.4, 85mm f/1.8, 17-85mm f/4-5.6 (my favorite!), and two kit lenses: 75-250mm and the 18-55mm.
Here are a few shots from around my farm:
