The Competition
When we tested the X100 in AP 23 April 2011, its only competitors were the Leica X1 and compact system cameras. Two years later there are a few more, such as the full-frame Sony Cyber-shot DSC-RX1, APS-C-format Nikon Coolpix A and the Leica X2.
The sensors of the APS-C models contain around 16 million pixels, while the RX1 has 24 million. Of the APS-C cameras, the X100S has the fastest lens at f/2, compared to f/2.8 on the Coolpix A and X2. Equivalent focal lengths are 35mm, 28mm and 36mm respectively. Like the X100S, the RX1 uses a 35mm f/2 lens.
The Coolpix A is the smallest of the these cameras and lacks a viewfinder or accessory port. An OVF slots onto the hotshoe instead. The X2 has an accessory port for an OVF or EVF, while the X100S features Fuji’s built-in hybrid viewfinder. The X2 has neither video recording nor live view.
