Sigma seems to have made progress in developing the 35mm (full-frame) Foveon X3 direct image sensor. In an interview with President Kazuto Yamaki, he said something to the effect that the sensor will be commercialized within this year. Foveon was originally a venture company established as a spinoff by engineers from National Semiconductor, and first exhibited the Foveon X3 technology at Photokina in 2000. It was Michihiro Yamaki, the company's founder and president at the time, who noticed the sensor and foresaw the digital camera era. In 2008, Sigma made Foveon a wholly owned subsidiary, and the Sigma SD9 was born. It was a digital SLR equipped with a Foveon X3 direct image sensor with a vertical recording APS-C size and a crop factor of 1.7x. The SD9 was improved to become the SD10. Furthermore, Sigma released the SD14 and SD15 digital SLR cameras equipped with the Foveon X3, named after Merrill, an engineer at Foveon, as the second generation Foveon X3 direct sensor. Furthermore, the Sigma sd Quattro and sd Quattro H mirrorless cameras were released, equipped with the Foveon X3 direct image sensor in APS-H size in addition to APS-C size, with a slightly changed structure. These mirrorless cameras used the same SA mount as Sigma's digital SLRs, and had a structure similar to a fixed mount adapter. This was the third generation Sigma Foveon X3 direct image sensor. After that, the company joined the Leica L-mount alliance and released the Sigma fp and fp L, full-fledged mirrorless cameras. However, the image sensor was not the Foveon X3 direct image sensor, but a Bayer array CMOS image sensor made by Sony. Behind the scenes, development of the 35mm Foveon X3 direct image sensor was continuing, but the company decided to scrap the development and start the development work from scratch. With President Yamaki's recent comments, the realization of the Foveon X3 direct image sensor is now on the timetable. The camera will naturally be a mirrorless camera, but it will be exciting to see what kind of image the new 35mm Foveon X3 direct image sensor will produce.

JPEG straight out of the box. No adjustments have been made at all. Photo taken in July 2019. This camera had a dual slot for recording media, one for CF cards and one for SD cards, but the Wi-Fi card was left in the SD card slot. For this reason, the images were recorded on the CF card, but since it was UDMA7 standard, I was not dissatisfied with the transfer speed. Canon EOS 7D Mark II, Tamron 16-300mm F3.5-6.3, aperture F8, 1/500 sec, AWB, ISO Auto.
