in broad generalizations, the wider the zoom range, the lower the quality. Itys been a while, but in the film days, there were a few 28-200 and a 28-300, and the 28-300 beyond about 200 mm was pretty poor quality. And wider than about 35mm, there was vignietting and a fair bit of distortion.
The exception is the AF Canon 5-500 f1.8 L IS zoom.
