Just got my first DSLR which is a Sony A300, and with it I have the kit lens (18-70). I'm in real estate and I'm required to take photographs of my listings, so I was wondering if someone could recommend a decent lens that would take great inside shots. Now I'm only a noob when it comes to DSLR photography, but I'm assuming it'd need to be some sort of wide angle lens to help give more depth?? Would love a lens that could be used for other shots aswell if possible and not just inside photographs eg. landscape What about a better flash, would that be required aswell?
