Hey all, so, I was at this party yesterday and a friend of my mother-in-law came over and asked me if I was interested doing Real Estate Photography - she's a realtor and just starting out so she's looking at different people right now she's gonna be able to afford and since my experience level is almost zero, she though she'd give me (and her) a chance. Now, I currently don't own a designated wide angle lens. I've been looking at several ones and I ahve to admit I'm fairly confused. I have to add I don't want to spend more than maybe $250.- right now. I would sooo appreciate some help from you guys, as I know most of you have a ton more experience as well as product knowledge than I do. Also, is it necessary for me to use external flash for this kind of photography or will I be ok using the compact flash which I know how to take the most advantage of)? I own a Nikon D50. Thanks!
