Pentax K1000 lens stuck on front

Look on the Pentax Forums for K30 aperture block

Yes, with limitations. The lenses will fit on any Pentax (now Ricoh) digital SLR. You may lose autofocus and/or auto exposure metering.

To repair this camera will be well over $100; my opinion not worth it. You would be better served purchasing another camera of the same type from ebay. An alternative terrific camera is the Pentax K1000, better yet K1000 SE. The SE has a split viewfinder, easy to focus. The K1000 have microprism that are more difficult to focus with especially in lower light; need good eyes. Then there is the Pentax K2, that at the time was their top of the line camera. All three cameras can be purchased for about $100-ish. Most will come with the Pentax 50mm f/2.0 lens.

Pentax makes a number of different 50mm lenses. Which one do you have in mind?

Although your lens is an older manually operated K mount and will physically fit onto your camera, there are incompatibilities which limit the level to which it is compatible with your *ist DS.

Ignoring the really obvious difference that your lens is totally incapable of autofocus, the first real incompatibility is that your camera body has one of the "crippled" versions of the KAF (autofocus) mount. This means that it lacks the mechanical stop-down coupler/indicator used on the original K mount. The result is that your camera body does not sense which aperture the lens is set to and will not stop the lens down to the selected aperture when you press the shutter release. The full specification KAF mount maintains these old mechanical legacy couplings, but as most owners don't use older lenses any more the crippled KAF isn't an issue to most users and significantly reduces manufacturing costs. Crippled KAF lenses can still use some manual K lenses, but only the ones which have the A setting on the aperture ring and your lens pre-dates this development.

Your only realistic fixes for this are to either replace the camera body with a model supporting the full KAF mount (expensive) or to use later K lenses with the description SMC Pentax A instead of earlier SMC Pentax M. You'll still lack autofocus but as long as the lens aperture ring is set to the A position then it will work when the body is set to shutter priority and Automatic modes. There are far more Pentax A lenses remaining in good condition than Pentax M so you should have no trouble finding them, but because of their compatibility with later mounts you'll find that prices are somewhat higher.

Note that there is no adaptor which will allow you to improve compatibility between your present camera and the lens you have asked about.

I hope that I've answered your question, if so please take a moment to rate my reply. If not, perhaps you should add a comment to further explain in which way your camera doesn't work with your lens and I'll then try to assist you further.

Sounds like the shutter is stuck. Same thing happened to my ALPA. I like you was unable to take it apart to repair, so many small tools required to take it apart. You could be better off sending it to New York.

Impact damage??? remove the lens and check the barrel for straightness. also the rear lens element must be perfectly straight. some of the latest lenses have a plastic helical gear that can be tapped out with a light hammer and a piece of wood ( 1in X 4in. ) used on the high end of the rear lens, if impacted.

Try this first.

Set your lens focus to infinity and focus your screen at a far away object (like a distant lampost). If it,s not in focus, then you have a misaligned mirror. Adjust your mirror so that a infinity setting, the split-screen image merge well to form a well focussed image. Hope that helps.

Yes the K100 uses LR44 or G13. I would recommend the G13

You can use any mm lens you want as long as it was made to fit the K1000.
Is the lens a Pentax lens ?
Push the lens release button down and turn lens Clock-wise then while holding release button down quickly turn lens counter clock-wise, it should come right off.
If it did not then it must be disassembled to remove the lens.
