Laowa 8-15mm f/2.8 FF Zoom Fisheye (Canon RF)

Testers found centre sharpness excellent wide open at 8mm, with the whole circular image sharp from f/2.8 and best around f/5.6 to f/8. At 15mm the centre starts very good while the corners need about f/8 to f/11 for their best. Lateral colour fringing is very low apart from some colouring at the rim of the circular image at 8mm, which crops away; coma is mild at 8mm but needs f/8 to clean up at 15mm.

Flare handling is judged average to better than average for such a wide view, though a ring flare and ghosts can appear with the sun near the centre and sunstars are irregular. Vignetting is moderate at around 2 EV wide open. The build is praised as solid metal; the main complaints are the lack of electronic coupling, the small zoom ring, an aperture ring that is easy to knock, and the 650g weight.
