The ultrasmall Meike fisheye 3.5mm f/2.8 has an impressive 220° angle of view. Just like the enormous Fisheye-Nikkor 6mm f/2.8 that Erik hauled around in Scotland during our 2016NG trip, but weighs 190g compared to > 5 kg.
I purchased the Meiko on a whim, admittedly, partly because it was offered very cheap partly for its potential use on my Olympus E-M1.2 in an underwater housing. After I few tries I retired the lens for that purpose and only when I later this summer got the Z Fc I was tempted to explore the tiny Fisheye again. It fits the Z camera through an m43-Z adapter, no problem, and of course will draw the full circle as the DX format is larger that its targeted sensor size.
I found the lens is quite sharp and with some judicious processing, the chromatic aberrations can be kept at a minimum. The überwide angle of view means you frequently get your hands, face, shoes or legs inside the frame. The consolation of course is anything near the periphery will be rendered small.
The image below indicates the Meike can deliver the goods as it were. In my neighbourhood we have a lot of ancient burial mounds, most of which are thousands of years old. The municipal planners try to ignore these when they plan a development as they only too well know a protected artefact will cost time, money, and efforts due to the mandatory archaeological excavations. However, many of these mounds are substantially sized thus not so easily "overlooked". The next best approach then apparently is "writing" the mound itself into the development scheme, in this case letting it stand in the middle of a new school yard.
