Sony Cyber-Shot DSC-RX100 In-Depth Review
Body & Design
The Sony Cyber-shot RX100 is a relatively conventional compact camera in terms of styling and control layout. In size, it fits somewhere between the Canon PowerShot S100 and the Fujifilm X10, but bears a stronger physical resemblance to the former. Like the S100, the RX100 features a twin control dial design, with a dial on the rear doubling as a four-way controller and control ring around the lens barrel on the front of the camera. Unlike the S100 though (and the Olympus XZ-1) the control ring is free-rotating and does not feature 'click' detents.
The RX100 is Sony's first camera to use its 'WhiteMagic' LCD technology (though Ricoh has already used it in its GR Digital IV). This uses four dots to make up every pixel on the display - adding a white dot to the existing Red, Green and Blue ones. As a result, the 1.2M dot display has the same 640x480 pixel resolution as the more common 920k dot designs, but with the ability to offer greater brightness. This can be used in two ways - it either offers the same screen brightness as one of the existing screens but with around half the battery drain, or it can be used to offer twice the brightness - which is especially useful outdoors on a camera without a tilting screen.
The RX100 offers an F1.8-4.9 aperture range across its 28-100mm equivalent range. Here we break down the equivalent focal lengths at which the aperture changes:
As is common in compact cameras with wide-angle lenses (and many mirrorless cameras), software correction of the lens' distortion is an inherent part of the design. This is one of the way Sony has been able to offer such a wide-angle lens in front of such a large sensor, while keeping the whole package down to a sensible size.
Most distortion is automatically corrected in the camera's preview and in its JPEGs. Corrections are applied when the Raw files are processed with Sony's own software or with Adobe's. Other third-party converters, such as DxO will offer their own corrections. Since correction is part of the camera's design, we'd conclude that any converter not applying the corrections doesn't fully support the camera.
