Panasonic just unveiled a new lens for Micro Four-Thirds, an 8mm f/3.5 fisheye offering a 180 degree field-of-view.  Frankly, I would have preferred to see more development by means of faster, more useful primes.  A fisheye is a “fun” lens on occasion, but I don’t own one for my Canon system.  Why would I get one for my Micro Four-Thirds body in favor of the system with the bigger sensor…especially since the announced price makes them comparably priced?  Yikes.
