Stabilisation uses a marker in the manufacturer model name; no marker is not a negative claim. Price filters use a current price when available.
One limit of this table: it lists only L-Mount lenses that mount natively on the Leica SL3 — lenses fitted through an adapter are not included here. See which mounts adapt to which.
