Is this lens worth it over a rectilinear ultra-wide?

Only if you want the fisheye look. A rectilinear ultra-wide keeps straight lines straight; this lens deliberately curves them and gives a full 180-degree diagonal view.

Can I use it for astrophotography?

Yes. The F1.8 aperture gathers plenty of light, and the wide view captures large stretches of sky, though stars near the edges will show the fisheye curvature.

Does it fit all Micro Four Thirds cameras?

It mounts on Micro Four Thirds bodies from OM SYSTEM, Olympus and Panasonic. It is a manual-focus-capable autofocus lens, so check that your body supports the features you need.

How close can it focus?

The minimum focusing distance is 0.12 m, which lets you place a subject very close to the front of the lens against a wide background.

Is it weather-sealed?

Yes, it is part of the PRO line with weather sealing, so it can be used in wet or dusty conditions when paired with a sealed body.

The lens comes with front and rear caps and a lens hood; check the listing for the exact included accessories.

About the OM SYSTEM M.Zuiko Digital ED 8mm F1.8 Fisheye PRO Micro Four Thirds Lens

The OM SYSTEM M.Zuiko Digital ED 8mm F1.8 Fisheye PRO is a prime fisheye lens for Micro Four Thirds mirrorless cameras. It has a 180-degree diagonal field of view and the curved look of a fisheye. The 8mm focal length gives a field of view equivalent to 16mm in 35mm format.

The optical design has 17 elements in 15 groups, including specialized elements for detailed image reproduction across the frame. ZERO coating helps reduce reflections and flare in challenging light. The maximum aperture is F1.8, and the seven-blade circular diaphragm stops down to F22. The minimum focusing distance is 0.12 meters, which allows close shots of nearby subjects against wide backgrounds.

The lens is dustproof, splashproof and freezeproof when used with compatible weather-resistant equipment. The lens hood is built in and cannot be removed. The front element does not accept screw-on filters.
