The fixed Carl Zeiss f/2.0 Sonnar T lens on the Sony DSC-RX1 comes with full manual controls, where you benefit from a maximum aperture of f/2.0 with 9 iris blades, delivering a shallow depth of field with attractive bokeh. As for the premium multi-layered T coating, that reduces ghost and flare caused by light reflection.
A quartet of four focusing modes, Single-shot AF, Continuous AF, Manual Focus and Direct Manual Focus are part of the equation, and you can select a maximum ISO setting of 25600, letting you capture images in low light conditions sans flash, although do expect plenty of noise to happen at that setting. The asking price for the Sony DSC-RX1 when it arrives this November? A whopping €3,200!
