I'd like to shoot round with my m43, how?
You're probably going to have to go for a C mount fisheye for a smaller sensor or APS-C circular fisheye with adapter/speedbooster.
Thinking about it, the Sigma 4.5mm is offered for both Canon and Sigma APS-C which have a 14.8mm and 13.8mm frame height, Four thirds isn't that far off it at 13mm due to the different aspect ratio (4:3 not 3:2) thus you might not even need a speedbooster with it.
You don't need a speedbooster, it fits on the sensor perfectly.
Depending on your quality requirements, a screw in camcorder fisheye adapter may work.
I suppose Hugin and other softwares should be able to "fish" any image, if this can be an option.
It can reproject to fisheye but without going to a lower focal length circular fisheye you won't get the full 180° hemispherical FoV.
Yes, but with the Rokinon 7.5 you should get reasonably close (or the 9 BCL if on a budget). From the post it's not clear if it is just about the look or if there are stricter FoV and IQ requirements.
Lensbaby has a circular fisheye but it may not be fully circular on mu-43, see the chart at
Also, another poster in that thread mentions a Sigma 4.5mm in Nikon mount.
Was there anything that people could have used to shoot circular fisheye in 1990, or 1980 that adapts well to MFT?
C-mount for 16mm, probably.
