A camera system includes an image sensor, an aperture, and an adjustable lens. The adjustable lens is disposed in an optical path of the image sensor to focus image light received through the aperture onto a pixel array of the image sensor. The adjustable lens includes first and second lens members and blackout regions. The first lens member includes a first corrugated surface and a first flat surface opposite the first corrugated surface. The first corrugated surface includes a periodic structure of alternating ridge and groove sections. The second lens member includes a second corrugated surface and a second flat surface opposite the second corrugated surface. The second flat surface faces the first flat surface. The blackout regions are disposed between the first and second corrugated surfaces and positioned to block the image light passing through either the ridge or the groove sections of the first lens member.
