It wont be my only lens i also have the lens that came with the rebel.
I mean is sounds logical to me correct me if im wrong. I know i do need to get more custom to setting my own aperture and shutter speed for the right environment
Im not going against your word I am just trying to show you my POV, i mean if this is a wrong way of thinking please correct me.
The pop-up flash is not
meant to be used as a primary lighting source. It doesn't matter how far back/how close you are, it will make your photos look bad. The pop-up is just meant to act as fill lighting, when the subject area is darker than the rest of the image.
Your camera also has settings to adjust the pop-up's power (but again, it's not meant to be used as a primary lighting source).
For portraits, with the $700 you're planning to spend on the Sigma 70-200mm f/2.8, you can very easily get your own basic lighting setup for the same price. A lighting setup when properly used would have a much better effect on your photos.
For $700, I'd grab a used Canon 85mm f/1.8 myself with a 430 EXII, off-shoe transmitter/receiver, and a beauty dish.

+1 to this. We're not trying to sound mean. It's just how it is with photography; in this case skill really will go much further with your current gear than with a new $700 lens.
