Originally posted by Pioneer Beyond the manual setting problem the idea of using some of my Takumar lenses with the K-01 is intriguing.
I need to spend some time playing with this setup. I like M42 Takumar lenses and I love the K-01. The combination should be terrific.
The K-01 has the same sensor of the K-5. If by chance you own both, the choice is based on the ergonomics, the WR, single or dual wheel, etc etc.
The quality of the raw files (and the dynamic range) of the K-01 are surprisingly good.
Despite some shortcomings the K-01 is still a solid performer. It is also good value because of a rather low second hand price.
Used with adapted lenses, for example Takumars or other M42 lenses, I personally find that the lack of a viewfinder and the highly reflective screen don't go too well with the use of manual focus lenses... BUT there is one thing that makes the K-01 invaluable.
It has no mirror!
Which means that ANY M42 lens can be used, even those with a protruding back element. No fear to damage the glass or the camera.
This comes very useful with adapted projection lenses. Some have long barrels, and once you fit them in a focusing helicoid, the back element has to go inside the camera, very close to the sensor, to allow for infinity focus.
Of all Pentax digital cameras, only the Q line gives more freedom, at the cost of a much smaller sensor and less dynamic range.
I am keeping my K-01 mainly for this reason. It is a great test bench for vintage lenses, including some old wide with very protruding back element, and "project lenses" originally not meant to take pictures.
