Probably because most of us have one Admit it, it's all about the blog...whatever. Go take pictures!!

For anyone else looking for a 70-200 foot, an alternative source is Hejnar Photo. Their 70-200 arca-compatible foot ($60) is almost half the price of the RRS foot ($100), and only $5 more than the RRS plate-only ($55) for that lens. The only disadvantage is that the Hejnar foot doesn't have a quick release, but for most people that's not an issue. In fact, the hex screw attachment method should theoretically make the foot more stable than the RRS foot.
