Ok Have you ever seen Jim Kramer's "Am I Diversified?". Well I like to be covered for all ranges in lenses. Right now I have a 70-200 L f/2.8 I USM. I am thinking about getting the 24-70 L f/2.8. However I would also like to get a bit more of a wide angle lens. I was thinking the 16-35mm f/2.8 II USM. However I noted a prime wide angle; the 14mm f/2.8 II USM. The 14mm is however 500 dollars more then the 16-35mm. Is that extra 2mm worth the money or is there something else that makes the 14mm that much better. By the way this is for a 50D body.
