Are pancake primes extinct ?

Well, Pentax has a range of small-ish (maybe not all pancake) lenses that are quite praised; it's one of the reasons I added a K-30 to my arsenal. They are not corrected in software for distortion (to my knowledge) and show decent to very good optical performance. Pricey indeed, but I suppose m43 producers can also hope to sell for similar prices if they offer good products.
