I am about to purchase the Canon Digital Rebel XT and have heard that the standard lense that comes with it is not that good. I am a novice and will mainly be using the camera when I travel and for outdoor shots. I am looking for a good, but not too expensive all purpose lense for everyday use. I am also considering getting a zoom lense as well if I can afford it. Can you all please recommend what type I should get? Like I said before I am a novice and really have no idea what I should get so I need specific recommendations. Thanks in advance!
