Hi Steph Johnson,
Numerous things could be the issue. 1, dirty lens, clean the front and back element, 2. The camera focus is not working properly not focusing on the correct spot. So, are you manual focusing or auto focusing? If it is auto then there could be an issue with that. If your are manual focusing are you sure your diopter setting is correct for your eyes, if not then it may appear correct in the viewfinder, yet be off focus.
Do you have a way to check the lens on a DSLR? If so you can try that lens on the DSLR seeing if there is an error with the lens or if it is your film camera.
There may be a few things preventing the camera from taking a picture. I don't know the lens you are using but by chance does it have an auto/manual switch that has been switched to manual? Also make sure the lens is locked in position. The camera won't take a picture unless it has focus in the auto focus mode, this is normal. What are you trying to focus on? The camera auto focus system will search and fail to auto focus on surfaces that have little or nor contrast. For example glass, chrome, a blank wall, water, blue sky. Other conditions that auto focus fails is being to close to your subject, heavy fog, a dim lit subject, available light and night photography. Once the little green confirmation light comes on the camera has focus and will operate as it should.
Turn the focusing ring on whatever lens you're using. You can use either the split-prism in the center or the the microprism collar and matte screen around it. For the split-prism, turn the focus ring until the two segments of the image divided by the horizontal line in the center line up. For the microprism collar and matte screen, turn the focus ring until the image appears sharp.
Hi ericm675, Yes they will. What you run into is were one uses a auto focus lens on a newer digital such as a D40. Some of the new digital cameras do not have the drive gear to turn the autofocus on the lens. Those newer cameras use electronics. Look on your camera lens mount at 7:00 you will see the drive pin. Look on your old autofocus lens you should see a slot where that pin fits. Hope this helps you.
There were years ago, but you did not have auto-focus or metering as I remember. Also there adapter had an optic that was not too good so the lens lost a lot of quality when used. Get an SRT-101 for use with the Celtic lens.
be sure batteries are good. pull up on the rewind knob to open film door. load film ,push down rewind knob. pull enough film to connect to take-up spool. close film door. advance film to counter # 1. look through finder and set meter ( push shutter button to turn on meter ) focus subject and fire shutter repeat to end of film. push rewind button ( bottom of camera ) rewind film.
remove lens by pushing button and turn lens left to remove.
Brush off any lose dirt from both the lens and bayonet mount and the autofocus drive shaft . If you are still not getting camera to auto focus your lenses have an expert look at the body : this is not an expensive problem to repair on these Pentaxes either a small mechanical problem or the connection to the pc board is bad. In either case only the front of the camera has to be dismantled ( +- 1 hour of labour to do the whole job ).
