Fujifilm has been producing lenses for decades now. The are m42 screw-mount lenses to be found, medium-format lenses on their fixed-lens 120/220 film rangefinder cameras, not to mention broadcast and cinema lenses. In this article, we will focus on Fujifilm’s current digital compact camera system with APS-C sized sensors and discuss the most common Fujifilm lens abbreviations you can come across while looking for a new lens to put on a Fujifilm X-E1 or other camera. I will also mention some of the common abbreviations found on other Fujinon lenses, too.
1) Fujifilm Lens Mount Abbreviations
The first thing that we need to talk about are the two best-known Fujifilm lens mounts:
- Fujifilm X-mount – this is the current, modern, fully-electronic lens mount used in Fujifilm’s mirrorless camera system with APS-C sized sensors. As of October 2013, there are five cameras that use this lens mount: X-Pro1, X-E2, X-E1, X-M1 and X-A1. Fujifilm X-mount has a flange focal distance (distance between lens mount and film/sensor plane) of 17.7mm. It is relatively new, but has gained some good traction with over 10 lenses currently available since its launch in 2012 and more to come soon. Lenses that use this bayonet are simply called Fujinon.
- Fujica X-mount – an old, mechanical lens mount used in the film era. It replaced the previous m42 screw-mount and was used by STX-1 and other analogue 35mm format Fujifilm SLR cameras. Fujica X-mount lenses are called X-Fujinon and X-Fujinar. The mount – and lenses designed for it – are now obsolete, but there are still plenty of old X-Fujinon lenses to be found in places like ebay at bargain prices. The Fujica X-mount has a flange focal distance of 43.5mm.
