Sony has just announced the DSC-RX100 III, another upgrade to the original RX100, following up on the RX100 II. This time, Sony has concentrated on improving the image quality and built-in features for ease of use. For example, the new camera includes a lens with a wider aperture at the full zoom range, enhanced video capability, and, probably most prominent, a pop-up electronic viewfinder. There is an excellent introduction to the new model at dpreview.com.
Although plans are not definite, at this point I expect to be producing a White Knight Press guide book for this camera this summer.
