Firmware and
Version Baseline
Use this page to record the firmware and software versions used when checking the guide. Body firmware, lens firmware, Pixel Shift Combiner, Lightroom Classic, and menu wording can change, so these notes should be reviewed after updates.
How to use this document
Read this first for the assumptions, limits, and checks behind the menu settings.

Current Baseline
This is the version state the guide is checked against. If your camera or software differs, the guide can still be useful, but menu wording, connection behavior, AF behavior, or Pixel Shift processing may not match exactly.
| Component | Baseline checked | Why it matters | Recheck trigger |
|---|---|---|---|
| Camera body | GFX100S II firmware v1.20, listed by Fujifilm as updated 09.02.2025. | Controls menu wording, wireless security behavior, AF revisions, and bug fixes. | Any body firmware update or reset. |
| GF lenses | Record each lens firmware with the lens mounted. | Lens firmware can affect AF, stabilization, aperture behavior, and update reliability. | Before trips, after buying used lenses, before updating lens firmware. |
| Pixel Shift Combiner | Mac 1.7.1 / Windows 1.7.0 current on Fujifilm download pages at this check. | Controls combine behavior, folder handling, DNG output, tethered Pixel Shift support, and Capture One integration. | Before any C6 or high-resolution archive work. |
| Lightroom Classic | Current Adobe Enhance behavior checked against April 2026 documentation. | Denoise, Enhance, DNG handling, masking, GPU requirements, and camera profiles change over time. | After major Lightroom updates or a new Camera Raw engine. |
| Backup/restore software | Fujifilm documents X Acquire and now points users toward FUJIFILM TETHER APP for backup/restore and tethering. | Backup workflow should follow the current Fujifilm software path, not an obsolete habit. | Before firmware updates or multi-camera work. |
What Can Change
Firmware and software updates rarely invalidate an entire manual. They usually affect small, high-consequence areas: connection menus, AF behavior, file handling, Pixel Shift combining, and post-processing behavior.
Update Order
Do not update the body five minutes before a job. Firmware work is maintenance. It needs power, a formatted card, time, and a recovery path.
- Charge a battery fully. Fujifilm warns not to turn the camera off or use controls while firmware is being overwritten.
- Back up or document settings first. Use FUJIFILM TETHER APP or X Acquire where available; keep a written critical-settings sheet as the field fallback.
- Update the body before lenses. Fujifilm notes that some lens-update issues are prevented by updating the body first.
- Update lenses one at a time. Mount the lens, check version, update, power-cycle, and confirm the new version before mounting the next lens.
- Reconfigure connection settings. After v1.20-style wireless changes, rebuild smartphone, FTP, Frame.io, and tether profiles deliberately.
- Run the six-bank critical check. Do not assume saved banks survived exactly as intended. Verify C1-C6 against the table below.
Body Firmware Checks
Body firmware changes have the widest reach. They can alter menus, network behavior, AF, and compatibility with external applications.
| Area | Check after update | Why | Related chapters |
|---|---|---|---|
| Wireless / Network USB | SELECT CONNECTION SETTING, smartphone pairing, Frame.io, FTP, tether profiles. | v1.20 removes older wireless menu paths and resets connection setting behavior. | Connectivity; Backup; C5 architecture. |
| AF tracking | Face/Eye, Zone, Wide/Tracking, AF-C custom set behavior. | AF revision history means saved AF settings may behave better or differently. | C2, C3, C4. |
| Custom banks | Mode dial C1-C6, Auto Update Custom Setting, EDIT/CHECK rows. | Any reset or update can expose undocumented temporary changes. | All setup walkthroughs. |
| Drive modes | Focus BKT, Pixel Shift Multi Shot, bracketing, continuous drive. | Specialist chapters rely on drive modes being reachable and named as expected. | C1 stacking, C5 stacking, C6 Pixel Shift. |
| Button assignments | Fn buttons, Q menu, focus lever behavior, touch screen mode. | Muscle memory breaks when a shortcut silently changes. | Settings overview; C3; C4. |
Lens Firmware Checks
Lens firmware is checked with the lens mounted. Treat each lens as part of the camera configuration, especially OIS lenses and lenses used for AF-C work.
| Lens | Bank role | Firmware-sensitive behavior | Post-update test |
|---|---|---|---|
| GF 20-35mm F4 | C1 and C5 primary wide lens. | AF at edges, aperture response, lens corrections. | Tripod frame at 20mm and 35mm; check edge sharpness and level workflow. |
| GF 45-100mm F4 OIS | C3/C4 workhorse; C1/C5/C6 selective. | OIS behavior, AF-C response, focal-length dependent shutter floors. | Handheld AF-C sequence and tripod/OIS-off verification. |
| GF 80mm F1.7 | C2 portrait primary; C6 still-life/detail prime. | Eye AF at shallow depth, aperture consistency, close-distance behavior. | Eye-focus test at session distance and f/1.7/f/2.8 comparison. |
| GF 100-200mm F5.6 OIS | Reach extension for C1/C3/C4/C5/C6. | OIS, long-end AF, tripod collar stability, minimum shutter floors. | 200mm handheld and tripod tests; confirm OIS switch discipline. |
Software Baseline
This guide is a camera manual, but two workflows depend on desktop software: settings backup/restore and Pixel Shift. Lightroom Classic also matters because several chapters assume a specific processing order.
Six-Bank Recheck
After every firmware or software change, run this short audit before trusting the camera for paid or unrepeatable work.
| Bank | Critical checks | Why it matters |
|---|---|---|
| C1 Landscape | IS/OIS off on tripod, ISO 80/100, self-timer or remote, Focus BKT reachable, Classic Chrome preview if used. | Tripod detail work fails through small stability mistakes. |
| C2 Portrait | Eye AF behavior, minimum shutter 1/200s for 80mm, IBIS on handheld, shutter state for flash if used. | Firmware AF changes show up first in face/eye work. |
| C3 Street | Electronic shutter, self-timer off, Auto ISO floor, AF-C SET 1 or intended street setup, wireless off. | Street work breaks when the camera stops being immediate. |
| C4 Indoor sport | Mechanical shutter, flicker reduction, AF-C SET 4, Pre-AF session exception, card speed, OIS/IBIS active. | Sport exposes buffer, AF, and lighting problems quickly. |
| C5 Architecture | Electronic level, ISO 80, mechanical shutter if flash/bracketing requires it, IS/OIS off on tripod, fixed/custom WB. | Architecture punishes drift in level, color, and stability. |
| C6 Pixel Shift | Drive mode, IS/OIS off, electronic shutter, stable continuous light, combiner version, source RAF preservation. | C6 depends on both camera and desktop software working together. |
Version Log
Keep a small version log with the camera kit. It makes later troubleshooting easier and stops firmware/software changes from becoming invisible.
| Date | Body | Lenses | Software | Manual action |
|---|---|---|---|---|
| 2026-05-12 | GFX100S II v1.20 | Record 20-35, 45-100, 80, 100-200 | Pixel Shift Combiner Mac 1.7.1 / Win 1.7.0; current LRC Enhance checked | Recheck six banks; update guide if menu wording differs. |
| YYYY-MM-DD | GFX100S II v... | Lens versions mounted and checked | LRC / Combiner / Tether App versions | Note changes, test C1-C6, revise affected chapter. |
