Originally posted by illdefined really hope Ricoh remembers to ‘activate’ those PDAF pixels in the new sensor with the next firmware, because it doesn’t make sense that it’s worse than one without them. and in their defense, it’s much much easier to fast autofocus the tiny sensor of the GRDs where most everything is already in focus anyway
Ricoh/Pentax tends to use slightly older sensor probably due to cost. So if comparing GRIII's pdaf performance to a slightly older sensor I'm not sure it's that different so I don't really expect it to be night and day difference with firmware updates. That said I'm probably just going to mostly rely on snap focus when it's too dark.
