Overview

The Fujifilm FinePix X100 arrived as a genuinely new kind of digital compact — an APS-C sensor camera with a fixed, purpose-matched prime lens and a viewfinder system that bridged optical and electronic design in a single body. The 12.3-megapixel APS-C CMOS sensor paired with the eight-element Fujinon 23mm f/2 lens produces files that reward careful light reading and deliberate composition. The 23mm focal length — 35mm equivalent on APS-C — is a classic documentary and street focal length: wide enough to include environmental context, tight enough to give the frame intention. At f/2, the rendering is warm and natural with smooth out-of-focus transitions; stop down to f/4 and sharpness across the full frame is genuinely excellent for a compact prime.

The hybrid viewfinder defines the X100 experience. A mechanical lever switches between a bright-frame optical finder — showing the scene in real time with a parallax-corrected frame overlay — and an EVF displaying a live sensor view with exposure and depth-of-field preview. The OVF is used for reading the scene and anticipating the moment; the EVF confirms exposure in difficult lighting. Physical aperture, shutter speed, and exposure compensation controls make the shooting experience tactile and immediate. The X100's operational limitations — contrast-detect AF with low-light hesitation, 720p video, modest LCD resolution — are real, and belong to a camera designed for photographers who prioritize still image quality and shooting deliberateness above all else. Those priorities are served exceptionally well.

Pros & Cons

👍 Pros

  • The 23mm f/2 Fujinon (35mm equivalent on APS-C) is engineered specifically for this camera body — the optical formula is optimized for this sensor size and distance, delivering edge-to-edge sharpness that a zoom lens set to an equivalent focal length cannot match at any aperture
  • The hybrid OVF/EVF system offers a shooting experience unique in digital photography — the optical finder delivers real-time scene reading with no electronic lag, while a lever-switch brings up the EVF for exposure preview, all in the same compact body
  • 12.3MP APS-C CMOS produces files with excellent tonal gradation and natural color rendering, particularly rewarding in black and white conversions where the sensor's tonal transitions between highlights and shadows are notably smooth
  • The compact rangefinder-inspired form factor draws minimal attention on the street — the X100's profile reads as an old film camera to passersby, which changes how subjects react and opens documentary moments that a DSLR or large mirrorless would close off
  • ISO range extending from 200 to 6400 (expandable to 100 and 12800) provides useful latitude across changing outdoor light conditions for a camera with a fixed prime lens

👎 Cons

  • The fixed 23mm focal length is absolute — there is no zoom, and the only framing options are physical movement or an optional conversion accessory that adds front-element bulk and image quality trade-offs
  • The original X100's contrast-detect autofocus hunts noticeably in low-contrast or dim scenes and misses fast-moving subjects that phase-detect systems would capture — patience and anticipation are required, not optional
  • HD video is limited to 720p — the X100 is a stills-first camera with minimal video capability; any serious video work requires a different tool
  • The 2.8-inch LCD at 460K pixel resolution is low by contemporary standards — live view composition and image review lack the clarity that modern high-resolution rear displays provide
  • The original X100 carried well-documented firmware quirks including slow startup, AF inconsistency, and modest battery life that were partially addressed through updates, but represent real operational considerations for a used purchase

Frequently Asked Questions

Absolutely. The 12.3MP APS-C CMOS sensor produces detailed, film-like files with excellent tonal gradation, particularly in RAW processed through Lightroom or Capture One. The 23mm f/2 Fujinon renders beautifully at f/2-f/4. The honest limitation is the contrast-detect autofocus, which requires more patience in low light than current cameras demand — but for deliberate, zone-focus street shooting, it is entirely capable.
No — the 23mm f/2 Fujinon is permanently integrated into the body. Fujifilm offers the WCL-X100 wide conversion lens and TCL-X100 tele conversion lens as front-element accessories that attach to the filter thread, approximating 28mm and 50mm equivalents respectively, though with some image quality trade-offs compared to the native prime.
A physical lever switches between two distinct viewing modes. The optical bright-frame finder shows the scene directly through a window with a parallax-corrected bright frame overlay — real-time situational awareness without electronic lag. The EVF displays a live sensor view with exposure and depth-of-field preview. Experienced shooters use both: OVF for reading the scene and anticipating the moment, EVF for confirming exposure in tricky light.
The X100 shoots Fujifilm RAF RAW files. Current versions of Adobe Lightroom Classic, Camera Raw, and Capture One all support X100 RAF files with full lens correction and tonal profile access. Fujifilm's own X RAW Studio also provides in-application RAW development.
At f/2, the lens delivers a warm, natural character with smooth out-of-focus transitions at close focus distances. Center sharpness is strong wide open; edge sharpness improves noticeably at f/2.8 to f/4. The 35mm equivalent field of view at f/2 produces portraits with an intimate, environmental quality that the focal length and rendering character support naturally.
