I've always thought it interesting that Pentax never got into any of the "alternative-to-35mm" formats, such as half-frame, APS, Disc, 110, 16mm, etc. Nearly everybody else did (including their current owner, Ricoh) -- of course some were big, costly flops! But NOW, they see an opening. Maybe it's Ricoh that's leading the way -- which has a rich history in half-frame:

the Pentax Auto 110 was (and Probably still is) the words SMALLEST interchangeable lens SLR camera.
and I love my Pentax 645. their was also a 67 which looks like an overgrown 35mm SLR.
Pentax also made several compact 35mm cameras.
