Using manual old K mount Prime lenses on a K5

Hi, my partner has just upgraded from her K20D to a Pentax K5 DSLR. She has a couple of old Prime lenses which worked well on the K20D but we cannot get them to operate on the K5. One of the lenses is a SMC Ashai Pentax 1:2 50mm and the other a Ricoh Rikenon XR 1:2 50mm.
When these lenses are attached to the K5 we get a Flashing F on the screen and no activation of the shutter release.
We have tried various settings including those that were used on the K20D.
Would appreciate any advice from forum members as to what if anything we are not doing or doing wrong. Cheers, Blair

Welcome aboard.

You have to go into the menu and set it to use the Aperture Ring. You also have to set the switch to MF for Manual Focus.

This is from an article here on the Forum:
The hard part is to get the camera to actually fire when a manual lens is mounted. In order to accomplish this, enter your camera's custom function menu, select the "Using Aperture Ring" setting (#21 on the K-7, #27 on the K-5), and set it to 2 (allowed). Once you do this, the shutter will at least fire, as it wouldn't have with this setting disabled (you would simply have seen an F-- indication on the top LCD/info screen). The setting description should read: 'Shutter will release when aperture ring is not set to the "A" position' when "allowed" is selected.
