The original Fujifilm X100 — the APS-C fixed-lens compact that launched a phenomenon, with hybrid OVF/EVF.
The Fujifilm X100 was released in 2011 as the original X-series fixed-lens APS-C compact, featuring a 12.3MP APS-C EXR CMOS sensor — a Bayer (not X-Trans) sensor, as X-Trans debuted on the X-Pro1 in 2012 — and a fixed Fujinon 23mm f/2 lens providing a 35mm full-frame equivalent perspective. The hybrid viewfinder provides both optical and electronic viewing modes. NP-95 battery. Approximately 445g with battery and card.
12.3MP APS-C EXR CMOS sensor (Bayer, not X-Trans). Fixed Fujinon 23mm f/2 lens (35mm equivalent). Hybrid viewfinder: optical frame with electronic overlay (1,440,000-dot EVF mode). No IBIS. NP-95 battery. Body weight approximately 445g with battery and card. Fixed 23mm equivalent lens; no interchangeable mount.
The X100's hybrid viewfinder was a landmark feature at launch: the optical rangefinder-style viewfinder could switch to full electronic EVF mode, combining the brightness and parallax-free framing of an EVF with the battery-efficient clarity of an OVF for different shooting conditions. The EXR CMOS sensor's Bayer design is distinct from the X-Trans pattern adopted from the X-Pro1 onward — image rendering is characteristic of the early X-series era.
On the used market the Fujifilm X100 is very affordable as the original X-series fixed-lens compact. Condition checks: EXR CMOS sensor for dust (known accumulation point), hybrid viewfinder optical element clarity, NP-95 battery health (specific to early X-series and FinePix), and 23mm lens element for marks. Fixed 23mm equivalent lens; no interchangeable mount.
