So there have been tons of threads here from n00bies like myself coming and asking dumb questions seeks advice on glass when they still have a lot to learn. With that said, I would like to get opinions from those of you who were once in my shoes or perhaps those of you who do photography professionally. Basically, I purchased a Canon Rebel XS the other day, so it came with the 18-55mm f/3.5-5.6 Canon lens. Not a terrible lens for everyday point and shoot stuff; however, I desire to begin learning with something a bit better. So my first choice for my next lens is going to be the 50mm f/1.8 Canon lens which I think would be not only a good fast lens but also a good lens to start getting the fundamentals down. With that said, I still desire to have a telephoto lens of sorts. I am looking at the Sigma Zoom Wide Angle-Telephoto 28-300mm f/3.5-6.3 for $300 from B&H, sure I would get a better lens if I spent $1000 or more but for now I just want a telephoto lens to get me started. I am open for suggestions in the $300-$400 price range. Thanks for any advice and further thoughts.
