Hey guys, So, I'm new here and finally I have the courage to make a big jump. I've been stuck with point and shoot for 3 years and I realized that I could do so much more with DSLR. Anyway, I need advice in choosing the right gears for my needs. Before I start off, I'd like to let you guys know that I'm a college student working part time job, so my budget won't be that much. I've been saving a little and so far I have about $650 to start. I like to take pictures of scenery, buildings (like downtown skyline), food, people, nature, and some airplane hobby. I looked around ebay and found this Canon Digital Rebel XT refurbished kit with 18-55mm lens priced well below 500 bucks. My friend also selling his 70-300mm f4-5.6 sigma lens for 165 bucks. He said that the lens is good for taking pictures of something in distance (zoom lense). Would you guys recommend those setup for beginner user like me?? Do you guys have any other alternatives solution that is affordable to me?
