X Series · 2012
Fujifilm X-Pro1
The camera that created the X mount.
Short answer
The X-Pro1 launched the X mount in 2012 with the first X-Trans sensor and the first interchangeable-lens hybrid viewfinder. It has 10 film simulations and slow autofocus, and it is now a cult object more than a working tool.
Fujifilm had a fixed-lens hit with the X100 and needed a system camera to follow it. The X-Pro1 arrived with three lenses, a new mount, a new sensor design and a viewfinder that switched between optical and electronic while changing magnification to match the lens.

What it started
The X mount has a 17.7mm flange distance and a 44mm throat, chosen to allow fast lenses with short back focus. Every X camera since uses it, and the original 35mm f/1.4 launched alongside the X-Pro1 is still sold.
The X-Trans sensor design, with its non-Bayer colour filter array, also debuted here and defined the look people associate with the brand.
What it is like now
Slow. Autofocus hunts, the buffer fills quickly and the menu is from another era. Manual focus by wire is poor.
What survives is the rendering and the viewfinder, both of which people still write about a decade later. Prices are low, and it is a lovely object to own if you already have a modern camera.
What is good
- The first hybrid viewfinder with variable magnification First-generation X-Trans rendering Beautifully built and now inexpensive Historically the start of the whole system
What is not
- Slow autofocus and a slow buffer No Classic Chrome or ACROS Single card slot, no sealing, 1080/24p video
Verdict
Buy an X-Pro1 as a second camera and an object of affection. As a primary camera in 2026, it will frustrate you.

Common questions
Can I use modern X-mount lenses on the X-Pro1?
Yes, all of them mount and work. Autofocus performance is limited by the body, not the lens.
Does it have Classic Chrome?
No. First-generation X-Trans bodies never received it.
