Given that Sigma's sensor seems so well suited for landscape/architecture I'm wondering is an ultrawide(20mm equivalent or wider) model possible? I thinking mainly about cost and whether the foveon sensor can cope with light coming in at a narrow angle.

Possible it should be. even wider FL.

Cost is something else, unknown here.

Since its a fixed FL, the sensor could be concave to match that specific FL and light would hit straight till the bottom of every pixel.

FF sensor have issues @ edges at WA and concave sensors could address those problems too.

If this is possible , Ricoh could make modules for diff. prime lenses and every Concave Sensor with diff. curvature  to match the specific FL of that prime.

maybe i am totally wrong here.


Hello J.,

with today's wafer cutting technology, it is impossible to produce a concave sensor. What it is possible, and Leica for instance does it, is to design and produce microlenses to be placed above each light receptor of the sensor, to "straighten" the light path at the edges of the sensor itself and allow light to reach the corners of the sensor. This microlenses can create problems, as they do with the Leica M series, when used coupled with interchangeable lenses; but it should create perfect results in a fixed-lens camera as the DPW Merrill would be.
