Hi,
There is a 23 mm from Rodenstock
Canon's 17/4 TSE L and 24/3.5 TSE L would be usable if the camera would have FPS
A lens like the SWC doesn't play well with digital sensor, because the symmetrical design gives large angles.
The effects of the large beam angles are:
Best regards

The effects of the large beam angles are:
- Vignetting (cos 4, and vignetting by pixel pits)
- Crosstalk between pixels
- Astigmatism caused by cover glass (can probably compensated in optical design)
Best regards

The SWC is 38mm on 56x56 format. That is ultra wide to me. To achieve that on 33x33 format requires a 22mm lens.
The available digital backs I could use on the SWC are not 56x56 format.
