- Sony's RX1 is the talk of the camera world, with a compact body, fixed lens, and massive full-frame sensor.
The Sony RX1 uses contrast-detection autofocus utilizing the image sensor. Users can select from up to 25 zones within the sensor's frame to focus on, with options for single autofocus, continuous autofocus, and manual focus. There is a focus mode dial on the front of the camera that allows users to switch between these focus modes.
The 35mm lens has a normal close focus distance of 35cm from the lens to subject. This can be adjusted, however, using the camera's macro ring, which is built into the lens assembly. The macro ring actually alters the focus assembly physically to allow the camera to focus as close as 20cm, offering a higher degree of magnification than shooting normally.
In addition, the camera includes a focus peaking mode, which allows you to highlight in-focus areas in a bright color to ensure proper focus acquisition when manually focusing.
Exposure & Metering
The RX1 uses the same 1200-zone metering system found on the rest of Sony's DSLR lineup. It has standard options for selecting center-weighted, spot, and evaluative metering. The RX1 has built-in HDR modes as well, for those looking to capture a wider dynamic range than the full-frame sensor will allow.
The Sony RX1 will include a native ISO range of 100-25600, though this is expandable to both ISO 50 and ISO 51200 in single shot modes. Through the use of the camera's multi-shot noise reduction, sensitivity up to ISO 102400 can also be achieved. This is slightly larger than the A99's range, which tops out at ISO 12800 normally, expandable to 25600 with the multi-shot NR mode (likely due to the translucent mirror blocking a percentage of the lens).
