Fujifilm's third-generation X100 — 24.3MP X-Trans III sensor with improved hybrid OVF/EVF and film simulations.
The Fujifilm X100F was released in February 2017 as the fourth-generation X100 fixed-lens compact, upgrading to the 24.3MP X-Trans CMOS III sensor with Acros film simulation and an improved hybrid OVF/EVF viewfinder. The fixed 23mm f/2 Fujinon lens (35mm full-frame equivalent) continues from earlier generations. The X100F was the first X100 model to adopt the NP-W126S battery, aligning battery compatibility with the X-T2 and X-Pro2. At approximately 469g with battery and card.
The 24.3MP APS-C X-Trans CMOS III sensor pairs with EXR Processor III. The fixed 23mm f/2 Fujinon lens uses 6 elements in 4 groups. Hybrid OVF/EVF provides optical viewing with overlay or full electronic viewing. Burst shooting at up to 8fps. No 4K — 1080p/60fps only. Battery life approximately 390 shots using NP-W126S in OVF mode (approximately 270 shots in EVF mode). Body weight approximately 469g with battery and card, single SD/SDHC/SDXC slot.
The X100F's 24.3MP X-Trans III upgrade from the X100T's 16MP X-Trans II is the primary image quality improvement — higher pixel count and the third-generation sensor provide better resolution and dynamic range. Acros film simulation adds a dedicated black-and-white mode with characteristic grain structure not available in the X100T. The NP-W126S battery switch improves availability (shared with many X-mount bodies) but breaks backward compatibility with the NP-95 batteries from earlier X100 generations.
On the used market the X100F is available at mid-range fixed-lens compact pricing. Condition checks: hybrid OVF/EVF switching mechanism, NP-W126S battery health — shared with X-T2, X-T3, X-Pro2, X-H1 — front element for marks (a 49mm accessory adapter thread accepts optional filter accessories), and leaf shutter for any irregular operation. The X100V (2020) added weather sealing and a tilting screen. Fixed 23mm f/2 lens; no interchangeable mount.
