Do you have any regrets about the gear you have purchased, or the company you bought in to? I'll start with myself. I somewhat regret going Nikon, because they do not make an F4 70-200 zoom (aside from the MF one). I was at a trade show today, looking at an 80-200 AF-D F2.8, the guy next to me was looking at a Canon 70-200 F4. My price was $675, and his was $450. I don't really need the 2.8 aperture, and the small size of the F4 is a huge plus. I wish I didn't have to spend so much to get an 80-200. So, what are your regrets, if any?
