Camera & Lense Recommendation

[Ruth]

Reeferaddict which lenses would you recommend? I also have a Canon 20D system. I have a few lenses for it but I think the 2 that I am happiest with (and yes they were definately the most expensive) are my 75-200 and a 100mm macro lense. I am looking for a wide angle lense and after a while go cross eyed trying to read and understand all of the info out there. Care to make a recommendation on a good zoom and wide angle lense for this camera.
