Originally posted by dwhopson My question is...am I better off to by the K-01 as a supplemental camera - OR - sell off my K100d-Super and Kx and buy a used K5/K5ii?
Owning two K-x cameras and a K-5, I picked up two K-01 bodies when they were going for USD 250.
While the K-01 does not quite have the dynamic range of the K5,
its less aggressive anti-alias filter seems to give sharper images.
I have one K-01 dedicated as an M42 camera, with the Pentax adapter permanently mounted.
The advantage of live view is that once you have the M42 lens focused (at open aperture),
you can frame the pictures at the taking aperture without having to mess with the preset lever.
Focus peaking also works very well. For example, it "tames" the 50/1.2 lenses.
The only downsides of the K-01 are that the screen can be hard to see in bright light,
even with the brightness cranked up to the max,
and that there is a slight shutter lag with fast action.
Nevertheless, you can work around those issues.
Anticipate for action, and shade the screen with a hand or hat.
Recently, I also acquired a K-50.
Its live view is not quite as good as on the K-01,
because you get the mirror flipping.
(Using an A50/1.2 on the K-01 in poor light,
I can hand-hold the camera at 1/13 sec with shake reduction,
and still get a sharp picture.)
