Ricoh only just refreshed its GR III camera lineup earlier this year with the GR III HDF, and it already appears to be ramping up to launch the GR IV early next year. The two new GR IV cameras are rumoured to launch in 2025 with a new sensor as the GR IV and GR IV Monochrome. Ricoh's GR-series compact APS-C cameras have always posed the biggest threat to Fujifilm's X100 line-up, but the X100VI stepped up Fuji's game significantly.
