Win a Pentax Limited Lens: Raffle Now Live!

Hi,

I'm new to the forum, and new to the pentax digital systems.

I'm having an issue I was hoping someone could help me with. I have a set of medium format manual focus lenses in Mamiya mount that I have had for years. I have successfully adapted these to work on cameras like the 5d II, d800e, and a fuji x pro1. I've never had an issue with these lenses until I got the K-1. I do have a good adapter to mate the lenses to the body, but for some reason, I cannot under any circumstances get the camera to show the exposure meter. This seems to go against most other camera makers, where when the camera is active the meter sits there and works when you half press the shutter or similar setup, reading through the stopped down lens. I understand that the lens would be used in manual only mode, and stop down metering would be in effect, but I can't get the camera to meter using either the optical viewfinder or the live view function. Am I missing some function buried in a menu somewhere?

I know it's an off the beaten path type of question, but any help would be appreciated!

Do you have a k mount lens available for testing? If so first verify the camera is working properly.

Switch to manual and press green button. Exposure changed or not?

You need to change a custom function and ensure that you're in M mode. Instructions below:

I was having this trouble with when a manual aperture ring on a lens was not set to "A". I would only get a DOF preview in the viewfinder.
