P.S. Actually Tv (shuter priority) mode also works with your lens. The "A" (automatic) setting on the lens is designed for shutter priority mode of film-era SLRs, when the user determines the shutter speed, and the camera automatically change the aperture setting in the lens according to metering result.

If you change to "Tv" mode, you shall see the top row shutter speed number turns blue. The shutter speed value will change when you turn the finger dial in front of the shutter release button, and the camera will determine the aperture value (you should see the aperture number change when you point to different areas of brightness).

There is also the dual "Av/Tv" mode which allows you to change both aperture and shutter speed for convenience, so that you don't have to shift from Av to Tv or vice versa.

Thanks you again. Yes, Tv mode gives me the shutter speed numbers and is changeable via the rear dial. And indeed the TAV mode works too. Thanks for the lesson on this manual focus lens and now I'm really happy I have the K50.

In a day or so, I'll spend some time outside getting some images from my "new" lens. From what I can see so far, the IQ looks like it will work fine for most anything. I'll shoot the models I usually work with (Border Collie and Chihuahua), but they are expensive and pretty demanding with treats, car rides, walks, etc.! Thanks again Fred and hoping you have a very good 2019.
