Lens: EF 75-300 f/4-5.6 III (telephoto zoom)
Good points: Metal ring at the front which allows you to focus in sharply. It also has an Auto Focus (AF) option and Manual Focus (MF). Currently I'm using AF as I find MF is leaving the pics a little blurred. I love this lens for long distance and action shots. Beautiful results!
Bad points: MF is a little difficult for me right now - I just need more practice and once mastered I'm sure everything will be hunky dory. Not good for close-ups as it will only come up super magnified ;) - but this isn't a lens intended for close-ups.
Why you should buy it: If you're looking to get a basic telephoto lens, this is a great starter option. I have no need to get anything more than this right now so I'll stick with it until I want to upgrade. You will get beautiful results with this lens on long distance shots. Oh yes and remember you're probably about a million miles away from your subject - you won't bump them with the lens ;).
For: Any Canon camera that will fit an EF lens. Or any other camera that has the right adapter to fit an EF lens.
