The EPIC sensor is 1.9:1. The 'ideal' aspect ratio for still images is 4:3 (but most DSLRs are stuck at the legacy ratio of 3:2, which is dumb but it's a waste of time to crop so I leave it as-is). Now, of course you can crop the EPIC's images to 4:3, but you waste a lot of pixels. So how about 'reverse anamorphic' lenses to stretch the image across the whole sensor width? From there, you have two options:
1. Keep the horizontal resolution (5,120 pixels) and interpolate only in the vertical dimension (stretch out 2,700 pixels to 3,840); or
2. Keep the vertical resolution (2,700 pixels) and shrink the horizontal dimension (5,120 pixels to 3,600).
The first option will maximize pixel count; the second option will maximize clarity and minimize noise (if there is any).
Just as an example of what the sensor would see with a reverse anamorphic lens (this bitmap is 400x210):
And an example of interpolating the vertical dimension as in the first option above (this bitmap is 400x292):
Of course your EVF or monitor would have to correct the image for easier composition.
FYI: If you're familar with Nikon's D1X, a 5.7Mpx camera, the photosites on its sensor are not 'square', and with some RAW software you could keep the entire horizontal resolution and interpolate the vertical so you'd get pseudo-10Mpx output.
