I recently purchased a 40D with 17-85mm lense and wanting to get into photography for a while. Question is, I am thinking about offering a maternity/engagement session for my future sister in law as a shower present. I have been trying to learn the camera and it's settings before her party in a few weeks.
My question is - am I crazy to undertake this? I thought it would be fun. We can take the photos outside (beach, park areas) and wanted to work with the lighting shortly before sunset.
Is this equipment a good start? Do I need another "basic lens" and an additional flash? I'll probably will rent, since I've spent a fortune recently. Help Help!!
Thanks so much for your time everyone 

Should I pick up a Tamron 28-75 or a Canon EF 50mm f/1.4 USM?
