System Boundaries
and Lens Expansion
This guide is written for still photography with a specific working kit. Use this page to see what is covered, what is left out, and how additional GF lenses should be added without rewriting the six-bank setup.

What This Covers
This is a still-photography field manual for a specific working kit. It is not a complete replacement for Fujifilm's owner manual.
Still photography first.
The guide covers still capture, bank setup, field technique, and Lightroom-oriented output. Movie settings, audio, timecode, webcam use, and full production tethering are acknowledged only where they affect still-photo work.
| Area | Status | Where handled | Boundary |
|---|---|---|---|
| Still capture | Fully covered | Settings overview and six bank walkthroughs. | Configured around C1-C6, not every possible Fujifilm menu combination. |
| Specialist still techniques | Covered where relevant | Focus stacking, Pixel Shift, filters, night/Bulb, lighting, maintenance. | Technique pages do not replace the bank walkthroughs. |
| Post-processing | Covered for Lightroom-led output | Lightroom manual and monochrome chapter. | Capture One and Photoshop are mentioned only where workflow requires them. |
| Connectivity | Covered as a still-photo support topic | Connectivity chapter. | Full studio IT, production delivery, and enterprise FTP management are outside scope. |
| Video | Excluded for now | Owner manual only. | Requires separate banks and a different operating model. |
Current Four-Lens Kit
The guide is built around four lenses because each has a clear field role. The point is not minimalism for its own sake; it is predictable behavior under pressure.
| Lens | Primary role | Strength | Constraint |
|---|---|---|---|
| GF 20-35mm F4 | Wide landscape, architecture, environmental context. | Controlled wide perspective without changing lenses constantly. | Not the default Pixel Shift lens; foreground distortion and edge discipline matter. |
| GF 45-100mm F4 OIS | General compression, sport, street, architecture detail. | Most flexible working zoom; OIS helps handheld banks. | OIS must be managed carefully on tripod and Pixel Shift work. |
| GF 80mm F1.7 | Portrait depth, static isolation, Pixel Shift prime for controlled detail. | Subject separation and high-quality static rendering. | Depth of field is unforgiving; not a moving-action lens. |
| GF 100-200mm F5.6 OIS | Long compression, restricted-distance documentary, remote architectural detail. | Reach without moving position; useful for distant static detail. | Slower aperture and long-end stability demand higher shutter speeds or support. |
Lens-to-Bank Map
Every lens can physically mount on every bank. That does not make every pairing equally coherent.
| Bank | Primary lens | Useful alternates | Avoid by default |
|---|---|---|---|
| C1 Landscape | GF 20-35mm F4 | GF 45-100mm; GF 100-200mm for distant compression. | GF 80mm unless the subject is static and deliberate. |
| C2 Portrait | GF 80mm F1.7 | GF 45-100mm for safer working distance; GF 100-200mm for restricted access. | GF 20-35mm unless environmental distortion is intended. |
| C3 Street | GF 45-100mm F4 | GF 100-200mm for distance; GF 20-35mm for environmental street. | GF 80mm if AF speed/discretion matters more than rendering. |
| C4 Indoor Sport | GF 45-100mm F4 OIS | GF 100-200mm when reach is required; GF 80mm for non-action moments. | GF 20-35mm for normal action coverage. |
| C5 Architecture | GF 20-35mm F4 | GF 45-100mm and GF 100-200mm for detail/compression. | GF 80mm except detail, product, or controlled still work. |
| C6 Pixel Shift | GF 80mm F1.7 | GF 100-200mm for distant static subjects; GF 45-100mm selectively. | GF 20-35mm for most scenes unless plane and edges are controlled. |
Adding Lenses
Add new lenses by job, not by wish list. A lens earns a place in the guide when it changes a repeatable field problem.
- Define the job first. What image problem does the lens solve that the current four-lens kit does not?
- Choose the bank it belongs to. Add to an existing bank unless the lens creates a genuinely new workflow.
- Write the shutter/stabilisation rule. Every new lens needs a handheld floor, tripod/OIS rule, and Pixel Shift position.
- Test AF behavior. Run AF-S, AF-C, face/eye, and close-distance behavior where the lens will actually be used.
- Update filter strategy. Thread size, step-up rings, vignetting, CPL behavior, and hood use must be documented.
- Update Lightroom expectations. Lens profile, sharpening amount, distortion correction, and vignette behavior need a processing note.
- Do not duplicate a role without a reason. A second lens in the same role must be faster, smaller, wider, longer, closer-focusing, or optically different in a way the guide can use.
Expansion Candidates
These are the logical ways the system could grow. Each candidate changes a different part of the guide.
Explicit Exclusions
These subjects are not omissions to patch casually. They require different working assumptions and should become separate chapters only when the guide can treat them properly.
| Subject | Status | Reason | What would be needed |
|---|---|---|---|
| Video / cinema | Excluded for now | Requires separate banks, audio, codec, shutter angle, stabilization, and post workflow notes. | A dedicated video chapter and bank map. |
| Dedicated wildlife | Excluded for now | The GFX100S II is not configured here as a fast wildlife system. Long-lens landscape and documentary reach are covered instead. | Long-lens AF, shutter, support, and field-carry chapter. |
| Full commercial tether workflow | Acknowledged | Connectivity chapter covers posture; full Capture One / studio pipeline needs a separate production manual. | Computer, naming, client review, delivery, and backup pipeline. |
| Every GF lens | Not the goal | The manual is stronger when it explains a coherent working kit rather than listing equipment. | Role-based additions only. |
| Third-party adapted lenses | Excluded for now | Mount behavior, EXIF, corrections, aperture control, and reliability vary too much. | Separate adapted-lens testing protocol. |
Revision Rules
A lens addition changes more than one page. Use this checklist before calling the guide updated.
- Update this chapter with the lens role and bank relationship.
- Update the relevant bank walkthrough with the lens-specific shutter floor, OIS/IBIS state, AF mode, and aperture range.
- Update the filter reference with thread size, step-up strategy, and vignetting notes.
- Update Lightroom or monochrome notes if the lens changes sharpening, distortion, vignette, or rendering behavior.
- Update the master index description so readers know the lens has become part of the system.
- Run a field test in the bank where the lens will be used before publishing firm recommendations.
