According to a press release issued on the 21st of February 2022 Sigma is still actively developing a new full-frame three-layer image sensor (Foveon). They currently are creating a prototype with a small sensor to test the characteristics of the new design. After this stage, they plan on prototyping the full-frame sensor.
In other words, we need to have a bit more patience. But it looks like a full-frame Foveon camera is still coming in the future. Fingers crossed.
Sigma press release:
Dear SIGMA customers,
First of all, thank you very much for your continued support and interest in our products.
SIGMA would like to share the development status of the three-layer image sensor as of February 2022 by the following.
The development of the three-layer image sensor is currently underway with the strong leadership of SIGMA’s headquarters in collaboration with research institutes in Japan. The stages of development can be roughly divided into the following:
● Stage 1: Repeated design simulations of the new three-layer structure to confirm that it will function as intended.
● Stage 2: Prototype evaluation using a small image sensor with the same pixel size as the product specifications but with a reduced total pixel count to verify the performance characteristics of the image sensor in practice.
● Stage 3: Final prototype evaluation using a full-frame image sensor with the same specifications as the mass products including the AD converter etc…
We believe that these three stages are necessary in the development, and we are currently in the process of creating the prototype sensor for Stage 2.
Based on the evaluation results of the prototype sensor, we will decide whether to proceed to Stage 3 or to review the design data and re-prototype “Stage 2”. When we proceed to Stage 3, we will verify the mass-producibility of the sensor with research institutes and manufacturing vendors based on the evaluation results, and then make a final decision on whether or not to mass-produce the image sensor.
Although we have not yet reached the stage where we can announce a specific schedule for the mass production of the image sensor, we are determined to do our best to realize a camera that will truly please our customers who are waiting for it, as soon as possible.
Once again, I would like to thank all of you for your continued support of SIGMA.
We will continue to strive for technological development to meet your expectations and trust.
