Is the laowa 6mm f 2 zero d mft worth it?
I'd call it worth a look if you want a wide view and don't mind focusing by hand. On Micro Four Thirds it frames like a 12mm lens on full frame, and f/2 gives roughly the depth of field of f/4, so a lot stays sharp. It's manual focus only and not stabilised, so it suits deliberate, slower shooting. I can't speak to the price, so check that against what you'd pay for an autofocus wide.
It fits almost every Micro Four Thirds body, but two good places to start are the OM System OM-1 Mark II for speed and the OM System OM-5 Mark II if you want something smaller. Read the Laowa 6mm f/2 Zero-D MFT page for the full list.
