I wonder what the limits of a "pancake"'lens are. Could they make a 14mm or 85mm pancake?
Since Pentax can make a 70mm f2.4 Pancake and a really small 15mm f4.0 for APS-C, I think it is not completely impossible but the Limiteds are a bit pricy unlike the EF40.
Wait till they include diffractive optics into the mix
