Turns the GR III's 28mm into 21mm with no crop and no image-quality complaints. Needs the matching Ricoh GA adapter, and it is not cheap.
The biggest change you can make to a GR short of buying another one. On a GR III it takes 28mm to 21mm; the neat trick the community worked out is that it screws onto the GR IIIx's GA-2 adapter too, so IIIx owners can go from 40mm to roughly 30mm. With a genuine GA adapter the camera actually detects it and displays WIDE. Two honest notes from owners: third-party adapters do work, but at least one owner traced focus-breathing problems to one and lost them by switching to the genuine GA-2; and the front element is bulky and exposed enough that people worry about scratching it.

“I took the gamble and sold my GR III for a IIIx + GW4 (for when I wanted that wide angle). I travelled NZ and the US with”u/m1nstral on r/ricohGR
GR III (21mm) - also fits IIIx via the GA-2
