Body elements

In a nice 'retro' touch, the shutter button is threaded for a mechanical cable release.
The small flash unit is placed rather close to the lens, roughly in the center of the front plate. It has a rather modest guide number of 6.4m at ISO 200, although as the camera manual is keen to point out, this does translate to a range of up to 9m at ISO1600.

Because of the X100S's lens shutter design, though, the flash will sync at all shutter speeds including 1/4000 sec.
In the center of the top plate is a hot shoe for external flashguns.

This switch, on the left-hand side of the camera, switches the focus mode between manual, single, and continuous.

The least useful option (AF-C) is in the middle, so you can switch between AF-S and MF quickly, by touch, simply by pushing the switch to its upper and lower limits.

The X100S's two connector ports, micro-USB and mini-HDMI, sit behind a hinged plastic flap on the grip side of the camera.
The battery and memory card live under a door in the base of the camera. The battery is the NP-95, as previously seen in the X100. Oddly it can easily be inserted the wrong way round, despite having an asymmetric shape (we were told this had been fixed with the X100S - apparently not).

The X100S is compatible with SD, SDHC and SDXC cards.
The camera's baseplate is also home to the tripod socket and the grille for the built-in speaker. The former is somewhat off-center from the lens axis, and very close to the battery/card compartment door (so you won't be able to change either with the camera on a tripod).
