"B. Limitations of FlatCam ... Achievable image/angular resolution. Our current prototypes have low spatial resolution which is attributed to two factors. First, it is well known that angular resolution of pinhole cameras and coded aperture cameras decreases when the mask is moved closer to the sensor [6]. This results in an implicit tradeoff between the achievable thickness and the achievable resolution. " Also the images speak for themselves - all very blurry.
