With its 16.1-million-pixel sensor, 15-point AF and 10fps with continuous AF, Sony’s Alpha 57 may suit aspiring wildlife and action photographers
All Sony SLTs, including the Alpha 57, use the company’s 1,200-zone metering system, offering multi-segment, centreweighted and spot modes. Spot metering is limited to 15 AF points, all of which are located within the central portion of the frame.
This can make spot metering a little awkward if the subject is off-centre. However, I suspect those interested in the Alpha 57 will generally stick to multi-segment metering, and this mode works effectively, leaning slightly towards underexposing for brighter results.
