About to finish a 3-year plan to round out my main lenses. I already have a 35mm f/1.4L and last year I bought the 70-200mm f/2.8L IS. Now I'm about to push the button on the 24-70mm f/2.8L. Now I'm planning on investing in other equipment. I figure after this lens, I'll invest in a good tripod. The one I have now cost $25 and is decent enough, but it won't support anything very heavy and it's not the most stable of things. I'll be getting a 580EXII flash unit this summer 'cause I'm doing a friend's wedding in Sept. and need an off-camera flash capability. I was considering getting Canon's 14mm f/2.8L II lens, but I already use my 35mm a lot to do panoramas, and I think I'm willing to do more stitching if it saves me $2000USD. I will be getting a new body, the 5D Mark II, but that won't be 'til 2011 and so may be a "Mark III" by that point. Is there any other equipment I should be looking at? What do you find is an important item that I may not have thought of?
