Originally posted by Boris Apparently I am not alone as Pentax is working really hard to produce very thing lenses, such as new XS 40/2.8 and I take it, they do so for the reason.
The following is my humble opinion, as a K-01 owner and user.
A
useable K-01 (
i.e. a K-01 with a K-mount lens mounted sans adapter) is roughly the same depth as a mirrorless APSc camera with a K-mount lens mounted
with adapter - or, for that matter,
any lens mounted, with or without adapter. In useable form a K-01 occupies similar pocket space as a smaller mirrorless APSc body with a lens mounted. The additional body depth of a K-01 permits a more stable grip, at least for me, than a smaller body.
Therefore the additional depth is rather a feature than a problem.
Q.E.D.
Pentax simply has a unique "take" on the mirroless advantage of small size.
