Some general points.......

The problem is that with (relatively speaking) cheaper lenses, they don't give their best results when used wide open. Even if your technique is perfect, a budget zoom wide open will give relatively soft images especially if used at max zoom. To get the best out of these lenses, you will have to stop down a bit to f/8 or even f/11 and pull the zoom back a bit from its max reach. At this point, you're starting to need a lot of light.
