Hi all, I'm building my list of lenses I would like to purchase in the next 3 months. This list is intended to be built from the ground up (meaning I have no lenses in my current arsenal). For telephoto I would like the EF 70-200mm f/4L IS USM. For macro and portrait I would like the EF 100mm f/2.8L Macro IS USM. Given these two lenses, I am having trouble deciding on a standard zoom lens. My two choices are the EF 24-70mm f/2.8L USM vs. the EF 24-105mm f/4L IS USM. I feel like the 24-70 is the better lens and would fit into the lineup with the first two lenses better. However, the lack of IS turns me off. What do you guys recommend? Thanks in advance!
