GR IV with the built-in Highlight Diffusion Filter — the soft-look 2025 variant.
The Ricoh GR IV HDF carries the Highlight Diffusion Filter variant concept into the GR IV generation, replacing the ND filter with the switchable mist-bloom effect introduced on the III HDF.
It shares the GR IV platform: a 26MP APS-C sensor behind a redesigned 28mm-equivalent GR lens, 5-axis stabilisation, snap focus, and 53GB of internal storage in the classic pocket body.
Its appeal mirrors the III HDF's: the diffusion look built in, no filters to carry, and the same one-handed street operation the GR line is known for.
As a recent release, used examples sit close to new prices; verify the HDF switch, check sensor dust and grip wear, and confirm box and battery count in the listing.
