This is according to a recent interview Quesabesde did with Sony’s Mr. Aoki who confirmed that KW1 did indeed come with a curved sensor. Back in July, Sony published a photo taken by the curved sensor and according to Sony, they claimed that a curved sensor allows for less vignetting and aberration that arises in flat and more traditional sensors.
Now we haven’t tested the Sony KW1 for ourselves so we can’t speak for its image quality, so we will just have to take Sony’s word for now. The good news is that according to Sony Alpha Rumors, they believe that this is the same sensor that will be making its appearance in a new full frame RX camera from Sony in the future.
They believe that this is the case as it was the same source who revealed the curved sensor in the KW1 to them, so there is a chance the source’s other rumor could also prove to be true. It will be interesting to see if that will really be the case, but we’ll keep our eyes peeled anyway.
