Question about Pentax K1000 35mm SLR Camera
When I look through the viewfinder there is a black splotchy spot in the middle of the frame. It does not show up on the negatives but it is quite an annoyance. Does anyone know how to fix this, if it is fixable?
It would depend on exactly where the splotch is. If it's on the outside of the viewfinder, you could simply clean it off with a damp cloth (and maybe some Windex or Formula 409). If the eyepiece is damaged, you can order a replacement part here.
Remove the lens and look at the mirror. If their is something on the mirror, you can carefully clean it. The mirror is very sensitive and vulnerable to scratching. If the reflective coating has been removed then you'll need a new mirror.
Look up at the bottom of the focusing screen. That's the more-or-less clear piece of glass that the mirror will reflect light from the lens onto. If there's a splotch on the outside, you can clean it off.
Those are the parts you can get to. If the splotch is on something on the inside, then you'll have to take the camera to a good camera shop to have a trained professional disassemble and clean it.

That's the mirror bumper, it softens the blow and cuts the noise as the mirror flips up.
Carefully remove it and then replace it with a new one. You can get it as part of a foam light seal repair kit for your camera; this also ensures that the sticky black goo which used to be foam and which prevents light from getting past the edges of the camera back gets replaced. Light seal kits are very cheap, and if you buy a pre-cut version then it makes a fiddly job a bit easier and potentially less messy. They're widely available on sites like ebay, just search for "k1000 light seals" and check that the kit includes a mirror bumper/buffer.
If you don't get it repaired the fuzz will get everywhere and can also get onto the film surface causing white spots on your photos or black spots on negatives/slides. The debris can also get into your lenses so remove it asap. Gooey foam light seals are even worse as it's both corrosive and abrasive (due to the grit it attracts) and gradually migrates to gum up the works. It can also result in light fogging on your photos (usually seen as red streaks from the top or bottom of the picture). Modern foam seals do not decompose like the old ones did.
I hope that I've helped you, please take a moment to rate my answer.

There could be a number of causes.
First make sure that the replacement batteries are up to it. Ie one's marketed for camera use. Others often cannot supply the current required by the motors. (Electric motors require most current just as they start, and so it may not do anthyhing at all.) Then check the battery contacts are clean. Much the same reason applies, dirty contacts cam prevent the batteries from supplying enough current.
One more simple possibility is that it does not know the battery door is closed. This may be detected by a protrusion in the film door edge operating a contact in the loctaing groove, or contacts in the door latch. There may be more than one!
It is also possible that the camera is detecting an impossible film. DX coded film uses the contacts inside the film chamber to read the film speed from unpainted sections of the film cassette. It is just possible that a dirty contact or a scratch in the paint is telling the camera that the film is a speed it cannot handle, or is just confusing it with a nonesense code!
Outside these there are a number of possibilites which will require internal investigation. You can try these camera repair pages for tips on repairing your own camera.

SOURCE: Can't get my lense off!
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.

This is not a user repairable problem.
You need to take it for a professional repair. The good thing is that this is an all mechanical SLR and was designed so that repairs are usually straightforward. Spares are no longer available, but so many of these cameras were sold and are still in use today that many repairers have a few scrap examples which they can cannibalise when needed.
Given that you can buy a perfectly good used K1000 at online auction sites for between £30-£40 it may not seem like an economical repair, but newly serviced ones with a guarantee sell for over £100 so it's definitely worth it for such a superb classic SLR.
