Good morning all,

I`ve just taken delivery of a Samyang T3.1 / 14MM ED AS IF UMC ULTRA WIDE Lens. It is a manual lens.

This is paired with a Pentax K1 ii camera.

I am getting the famous flashing F - - regardless of what setting I have the camera in. I realise from previous reading that this is the camera (super intelligent as it is) telling me that it can`t set the aperture. This leaves the camera unable to take any photographs

How can I clear this "error" message?

Many thanks

David

Menu C4 line 26 allows you to enable / disable use of the aperture or page 111 of the destruction manual

Excellent - many thanks Chris.

Now I need to remember to change it back when I use the other lenses

I leave mine set as above, imo no need to change it back, then whenever you use an older lens ( non A lens ) it just works as it should

You will need to use the camera in M mode for the lens to stop down.
