X100

X100 is a model designation used by Fujifilm for a line of fixed-lens digital cameras that began production in 2011. The line is known for its non-interchangeable 23mm f/2 lens, compact form factor, and a hybrid viewfinder that blends optical and electronic viewing options, appealing to street and documentary photographers.

The original Fujifilm X100, released in 2011, paired a fixed 23mm f/2 lens with a 12.3-megapixel APS-C sensor and a first-generation hybrid viewfinder, allowing users to switch between optical view and electronic view without changing cameras. It emphasized manual controls, build quality, and Fujifilm’s film simulations.

X100S, announced in 2013, updated the camera with a higher-resolution X-Trans CMOS II sensor and faster autofocus, while keeping the fixed 23mm lens and retro styling.

X100T, introduced in 2014, was a mid-cycle refresh that improved autofocus performance and handling, added new film simulations, and refined the control layout while maintaining the core X100 design.

X100F, released in 2017, brought a 24.3-megapixel X-Trans CMOS III sensor and faster processing and autofocus, continuing to use the same fixed 23mm lens and the familiar body design.

X100V, launched in 2020, redesigned the body for better ergonomics and weather sealing, introduced a redesigned 23mm f/2 lens, and upgraded to the X-Trans CMOS 4 sensor with enhanced autofocus and 4K video capability.

Outside Fujifilm's X100 line, the X100 designation has limited use and is not widely assigned to other consumer products.
