POS, or at the bar
No, not what you're thinking. Here, "POS" abbreviates "point of sale." As in, where you go to buy cameras. I hate the camera bar. Or, as I've described it elsewhere, the "camera anchorage." That semi-circular tier of cameras on display, where every camera is attached to a weighty metal anchor which, in turn, is cabled to the display. This is the worst way to experience a camera. You can't tell how a camera feels in your hands if it's bolted to an anchor. You can't tell if it's lightweight or too heavy. And you probably can't tell whether its tripod socket is in a centered position or off to one side. I want that experience. More to the point: I want to power up the camera and see if it works as I expect. That means the power connector from the camera bar has to operate. Which it seldom does. Target, Walmart, BJ's and Best Buy all have a variant of the camera anchorage, and every one I've experienced has electrical issues...
