Conclusion: Good all-around general purpose lens, versatile enough for many situations. Relatively light weight. Good for a walk in the woods because it can capture a decent wide-angle landscape shot, yet still take a great close-up photo of an object along the trail, such as a flower. Limited zoom means it cannot get a close-up of distant wildlife, so if that's your target, you will need to consider a different lens.
Pros: lightweight, takes good photos at night, wide angle
Summary: This is the starting point for everyone, and while the Newer usm versions with IS are cool, I like this one more, im a sucker for simpler tech. You have to really work this lens, alot of things can be learned with it.
