My K1 does not give enough "F" (DOF)

Hyperfocal focusing does not really work with 28/2 Distagon. Why? Its focusing field is almost spherical instead of flat plane. Use liveview to get it sharp where you want it sharp. Only at f/8 it gets somewhat flat.

First, OP said that "..distagon f/2". If it is 28/2 Zeiss then it is dead end for handheld landscape shooting. That is one of the most difficult lenses to focus correctly and requires live view at every aperture to get far distance focusing right. Almost the same story for every other distance. If shooting without a tripod is must, then get a mirrorless body to go with the Zeiss to get some idea where it is focused at.

Another issue IF that lens is Leitaxed Zeiss: Light metering is more or less guesswork even with the green button. I had Leitax 28/2 Zeiss and used external light meter to get things right.
