To be honest none of these are that interesting. Maybe the slr magic 8/f4 since it is somewhat unique but it sounds like it is meant for drones and not general use. Early reviews seem to indicate it isn't that great though the center is fairly sharp. Hum checking a few others I don't think it is worth the effort to vote. None them excite even as a curiosity (I've never liked circular fish-eyes myself).

Btw is the yn50f1.4 II actually available ? Couldn't find any existing commentary and iti s preorder at b&h
