Pentax k1000 light meter issue

SOURCE: Exposure needle not working

clean the battery cover and contact with a pencil eraser making sure the cap threads are also clean.
this is a fairly expensive repair if the meter or circuit board needs replacing ( no new parts are available ).
if the meter still does not work, and the K1000 is in good working order buy a inexpensive hand held light meter.

Unfortunatly I am in Brazil and not aware on repair services in Mumbai. BUT addressing your question, YES all Pentax mount (bayonet) will fit in K1000. As a matter of fact, this is an extremely reliable and simple camera, assuming you are skillful in manual mode shooting. In the "used" market you can find a lot of bargains suitable to the K1000. Try some oldies (but goldies) Takumar lens.

Clean the battery cap and contacts with a pencil eraser including the cap threads.
there are no new parts available for this model Pentax, so a good used part repair could be expensive.
An inexpensive hand held light meter might be the way to go if the cleaning did not work, and the camera is otherwise working good.

The light meter has failed.

You can usually get it repaired (it's even possible to do so on a DIY basis if you're fairly handy, just search "k1000 meter repair", click here for one immediate possible fix), but it may be cheaper and easier to obtain a handheld light meter instead.

If you do get it repaired then at the same time get a full CLA service (Clean, Lubricate, Adjust) and have the gooey foam light seals replaced. Some repairers may try to charge extra for the latter one-off job, but usually do it for free when you smile and politely point out that you can take your business elsewhere.

Although simple and very basic, a good clean K1000 in a freshly serviced and fully functional condition is one of the only Pentax 35mm SLR's which is still worth reasonable money simply due to high demand for them. If you choose to keep it then it should be good for many more years of flawless service.

I hope that I've helped, please rate my answer.

Testimonial: "thanyou for your advice. The light meter was the problem"

SOURCE: I recently dropped my Pentax

Unfortunately, this is a serious problem.

If the focus ring is not working then there is serious damage inside the lens. This cannot be repaired easily and must be taken in for repair.

As for the light meter, this is slightly more worrying as it is damage inside the body. It could be something as simple as the battery contact. But it could also be somehting more serious.

I would recommend taking it for repair.

If repair turns out to be too expensive I suggest you have a look on ebay. Pentax cameras are available with a wide range of prices and so are compatible lenses. A good upgrade would be a Pentax MX or even an LX if you can afford it. The ME super is also an excellent model if you want soemthing simpler.
