I'm going to start off by saying that this lens is one of the best all-purpose walk around lenses you can own. With a range from 24mm to 105mm, you can't beat the versatility. On the close end, 24mm acts as a great wide angle lens with great sharpness and minimal vignetting. 105mm allows the photographer to have the extra reach when changing lenses isn't ideal. I use this lens mostly for landscapes such as waterfalls, and it works like a charm! I have also used it for some portrait work and it has treated me well there too. I love this lens to death! It was the firsts lens that I got with my full-frame, and it will probably be by my side until the end.
