No, nothing like the first to exist. But the first I’ve owned (I’ve had two that include 14mm since pretty much the beginning; that’s the angle of view of a 28mm on old 35mm film—not all that wide. 12mm is fairly wide, and they’ve been common for a while, and there are one or two good 7-14mm zooms, too.
But a 7.5mm f/2 for half or less of the price of some of the good alternatives was very interesting. Too soon to really know about performance, but it’s a nice wide lens!
