You can use lenses you used on your Pentax K1000 on Pentax DSLR's.
One the great features about using Pentax Digital Single Lens Reflex (DSLR) systems is that you can use old manual focus lenses that you would have used on the legendary Pentax K1000. Not only can you use old manual focus lenses, you can also still benefit from Pentax's "Anti-Shake" program as it is part of the camera body as opposed to being part of the lenses as it is with some other manufacturers. When you are attaching an older lens to your modern Pentax DSLR there are a couple of settings you will need to change.
Attaching the Lens
Attach your old K1000 lens by lining up the guide dot on the outside of the lens to match the guide dot on the camera mounting ring. Place the lens against the camera body and rotate the lens until it clicks into place.
Using Manual Settings
Switch the "AF/MF" switch located on the front of the camera to "MF" for manual focusing. DSLR's do not have focusing screens like the K1000 does. However you will know your lens is focused correctly as the center focusing point will illuminate and the focus indicator light along the bottom of the viewfinder will also be lit.
Setting Aperture
Press the menu button located on the back of your Pentax DSLR and toggle through the menus until you reach "Using Aperture Ring" press the "OK" button. Change the value in this menu from "Prohibited" to "Permitted" and press the "OK" button to save your selection.
Meter
Turn the exposure mode ring located on the top left of your Pentax DSLR to either "M" for manual or "Av" for aperture priority. Use the aperture ring on the lens to select the aperture you want to use. Press the green button just beside the shutter release to stop down the lens and activate the metering mode when using older lenses.
Take a Picture
Turn the focusing ring on the lens until your subject is in focus and press the shutter release button to take the picture.
