Honestly, the new Olympus fisheye is a fantastic lens. Image quality, even wide open in the corners, is hard to believe. It gives you an amazing amount of freedom for existing light photography. I was doing video of a shipwreck at dusk a few months ago. We had placed lights on the wreck, and I had a diver swimming up the length of the ship. You could just see the glow of dusk in the background. I was using the Panasonic 8mm f/3.5, and had to jack up the ISO to 800-1600. The Olympus would have allowed me to reduce the ISO to 200-400. On a Micro 4/3 camera, that means a huge difference in image quality.

 

I use mine behind the Zen DP-120 with no spacer ring. An absolutely perfect combination.

Hello jplaurel!
What do you think about autofocus speed? I am wondering how it improves over the panasonic, were you using it before?

Both are fast. The Olympus focuses on my GH4 really, really fast, even in low light. I have not compared them directly, but my subjective opinion is that the Olympus is faster. Maybe it has something to do with giving the contrast detect AF system more light to work with.

I recently used one in the Maldives. This lens' raison d'etre? Speed. Here is a shot, taken just after sunset, wide open (f/1.8) at ISO 1600. The Olympus 8mm allowed me to keep a shutter speed of 1/160 sec to stop the action. It would not have been possible with the Panasonic fisheye without raising the ISO by 2 stops, to 6400, which would result in too much noise, or by lowering shutter speed to 1/40 sec, which would result in motion blur.
