Don't let that little letter fool you — the X100s is a completely new camera underneath the external chassis.
Fujifilm has announced a successor to the rangefinder-style X100, which featured a hybrid viewfinder. Though the body and lens is the same as its predecessor, the X100s gets a new sensor, AF system and viewfinder.
The sensor is a 16.3-megapixel APS-C X-Trans CMOS II, which uses a similar technology to that found in Fuji's interchangeable lens camera (ILC) range, also dubbed the X-series. A digital split-image feature shows the same image on the left and right of the viewfinder to line them up for precise focusing. Focus peaking is also available.
Thanks to the new processor, Fuji is claiming the world's fastest AF at 0.08 second (compared with other cameras with a Four Thirds-sized sensor or larger). The X100s can record 1080/60p video as well.
Also on the agenda is the X20. This is an upgrade from the X10 (no surprises there) and keeps the same lens as before. A 12-megapixel 2/3-inch X-Trans CMOS II sensor and focus peaking appear as well. Speed is also touted on the X20, with AF cited at 0.6 second.
No local pricing or availability for either model has been announced, though the X100s and X20 will be available in the US from the end of March for US$1299.95 and US$599.95, respectively.
