Issue Using M Lens On K-X

The camera has a combination (shutter) of shutter speed and aperture for each exposure value (EV) programmed in memory. Think of EV as the amount of light or brightness of the scene. The program line is this set, recommended for the situation.
This article explain this in detail: Pentax Green Button Guide - Articles and Tips |

See the graph in the article to understand.

When the camera is in manual mode M, with a lens without aperture ring or lens with aperture ring in position A, the green button sets the aperture and shutter speed according to the program line. If the lens has an aperture ring out of position A or an M or K lens, the green button sets the shutter speed for the aperture selected on the lens.

I checked my k-x and *ist DL. In k-x we can use the green button or the AV button to obtain the correct shutter speed automatically, in M mode with a lens with aperture ring. In *ist DL the button to be used is the AE-L button. Same result in both cameras, the shutter speed set correctly.

You have to set Green Button function to Green Button, and not to Optical Preview. Then it will appear two options bellow Green Button. One for M Mode and other for Program Mode.

The K-X has its own green button. The older cameras as the ist series do not have green button.

In my K-X, the green button is set to P-line in M mode.

When I press the AV button in M Mode the lens stops down to the ring setting and sets the correct shutter speed. It is the same behaviour as I press the green button.

You must set the manual exposure mode (M in dial). Then, when you press the green button, the camera sets the shutter speed to the correct value. Nothing more is needed.

You will need a slide copier, bellows or extension tubes, a 50mm standart ou macro (better) lens. See this for doing it with an APS-C instead of full frame. The process is the same, only magnification needs to be diferent.

I use Gimp to process details and color. Also Pentax/Ricoh Digital Camera Utility for cataloging and raw conversion. I am also considering to use Darktable in my workflow.

In my film days I used a 24mm, a 35-70mm and a 70-210. All in a SFX autofocus body. Other possibility is to have the film trio (28-50-135).

You could use a slide duplicator to digitize with a DSLR. Pentax have a recently introduced and vintage ones. Also, it is easy to DIY an apparatus to mount the negatives or slides.
