A new Macro lens!

I just ordered my own Christmas present! The "Sigma 105mm f/2.8 EX DG Macro for Canon AF". I have wanted this lens for quite sometime but was going to wait until spring to order it. But, then I thought "why not order it now and really run up the old credit cards" ... haha After all, it is Christmas time :O) I ordered the "Sigma Electronic Flash EF 500 DG Super for Canon AF" and a cable shutter release a couple of weeks ago. I haven't messed with the flash much yet but I'm sure it has to be much better than the "on-board" flash on the Rebel. I have read good reports about this Sigma flash in all the photography forums. I should receive the new Macro lens on Dec 21st. I just love it when that "brown" truck pulls up in front of my house!
