This is my first post, so hello everyone! I am looking to purchase a DSLR to use for 2 purposes: 1. I buy & sell houses, so I will be taking pics of the completed properties, and need something with a really wide angle so I can show the entire bath, kitchen, etc. 2. getting into the photgraphy hobby So here's my question...I was looking at the D40X and wanted to purchase some great lenses without spending a fortune, so 1. do i need a fisheye, or just a wide angle for my #1 need above, and 2. whats a great first lens for general use....nature, portraits, digiscoping (i have a Swaro ats-80hd with a 20-60x), etc. THANK YOU !!!!!!!!!
