I think the 70-200 f/4 IS is sharper than the 70-200 f/2.8, and is less expensive. The IS is better and when you upgrade (and you will), to a different body, you will still have great glass. The EF-S series will not work on full frame cameras... the EF series will work on both crop bodies and full frame. The 70-200 f/4 is agreat lens at a great price for what it is. Get a 100 Macro later.
