    Same with me. I’ve been watching the information come out on this lens, but I’ve never heard of a pancake lens before. What’s the “why for” on this?

    Everything old is new again! Back in the 1960s, when CANON had the PELLIX in their product line, they had a 38mm lens, which could be called a “pancake” lens, since it was very short. It was designated as the FLP 38, but was specifically designed for the PELLIX, since that had a stationary pellicle mirror, so part of the lens could encroach in the chamber normally reserved fro the swinging mirror.
