Samsung NX100 Preview: 1. Introduction: Digital Photography Review Samsung has announced the addition of the NX100 to its NX series of mirrorless interchangeable lens cameras. It features the same 14.6Mp sensor and 3.0" OLED screen as the NX10, which are built into a flat, 'compact camera style' body. It also offers the i-Function feature that allows the use of the focus ring to control various camera functions when using compatible lenses. To complement this feature the company has launched two lenses with i-Fn buttons - the 20-50mm F3.5-5.6 ED kit zoom and 20mm F2.8 pancake lens. There is also an electronic viewfinder, flashgun and GPS unit to accompany the NX 100. We've had a pre-production NX100 for a little while, so have produced a quick hands-on preview.
