Well now, it appears as though I may have opened up a can of worms with this issue, as I have discovered a problem with the K-7, however I will have to post that in another thread.
I went ahead as suggested and cleaned the contacts in both the camera and the lens. Went through every line item in the Menu, just to make sure I did not personally throw a monkey wrench into
the works. With the aperture ring in the "A" Position, I mounted the lens back onto the k-7 body and the camera asked me for a focal length. I had no choice other than 300mm and then took a few
shots, checked the EXIF data and sure enough, Focal Length showed up as 300mm. The auto-focus functioned great up to 160mm and then quit. At that point I had to use the shutter speed and ISO settings in order to produce a decent image.
I just recalled that I had the same exact problem with a Pentax-M 40~80mm Macro lens and I did not know which number to enter, 40mm or 80mm? So whatever I entered, that is what appeared in the EXIF data, and again, that is a Pentax-M lens.
I will mention briefly the other issue I discovered with the K-7. When I attempt to change shutter modes, I noticed that when I enter AV and then attempt to change to TV, it stays in AV Mode according to the read out on the back panel. The only setting that changes properly is M for Manual Mode. I wonder if these two issues are related. I will go ahead and post this latest discovery in the proper thread section heading. Thanks for the info. Am I confused? Aaaaaahhhh, Yup.! I wonder if the lenses are too old for the k-7. Tonytee.
