To give an indication of the maximum magnification you can get with fisheye lenses for macro, two more images of the Canon 7.5mm FD, wide open and at f/16, buttercup touching the front lens:
Another fisheye, the Samyang 8mm f/3.5, I forced into macro mode by mcgyvering an EF to Sony E adapter slightly longer than the regular adapter (Novoflex Eos-retro, 58mm distance ring, 58mm reverse ring for Sony E). Obviously it wasn't intended for full frame use. At f/3.5 and f/11, subject touching the front lens:
And finally a lens with an even shorter focal length, a Yashinon 6.5mm f/1.4 D mount lens. At f/8, with a Schneider Cinegon 8mm f/1.4 (2.0) as a relay lens. This results in a nice and compact setup, but it may be improved upon. Certainly the Yashinon being taped onto an extension ring doesn't guarantee a perfectly parallel setup. Still, it gives you an idea about maximal magnification and how much of the background you can see this way:
