two pancakes, one crêpe

Many have extolled the virtue of the Pentax DA pancakes: 21mm, 40mm and 70mm Limited primes that serve very well and are tiny to boot.  At one time I owned the DA40 and 70 at once, and I liked them very much but the budget demanded a sacrifice.  I later picked up the DA21 so my lifetime triple was complete!

Now I have picked up a new 40mm - not the DA Limited but the XS model that came with the K-01.  If the others are pancake lenses, this is surely a crêpe as it's substantially thinner.  It loses quick shift but is optically the same excellent lens; I look forward to using it to replace my lens cap! :^)  Actually the lens-cap for this is about the size of a rubber quarter, so hopefully I shall be able to keep track of it.

The fourth prime is a Sigma 105mm macro, which is larger and heavier than these three combined.  Hopefully I can justify carrying such a 'beast' now and then!
