Originally posted by Stone G. With genuine SMC Pentax M lenses and a K-5 you should surely be prompted every time you turn your camera on. Non-Pentax lenses with PK-mount can be "peculiar" with the K-5 if the mounts are oxidized / black-anodized and, hence, do not shorten the contacts on the K-5 body.
So, please tell us what specific lenses you are using --- and maybe try cleaning your K-5 contacts gently?
All SMC Pentax lenses: M20 f4, M28 f2.8, M50 f1.4, M100 f2.8, M200 f4 and K200 f4
The contacts on the camera are spotless and the lenses show now signs of dirt or oxidization.
I don't want to send the K5 back and then find that it's some anomoly in the menu ( not coming on because of another setting )
It's no big deal as I'm now into entering the F.L. habitually
