Hello,
My pentax k1000's mirror was dirty so i cleaned it with some acetone (bad mistake) i got some on the condenser lens and it seems it made it murky/ghosty.
It's annoying when taking photos as the viewfinder displays the ghosty images.
Is there a solvent able to remove this? or is the plastic lens damaged? if so can i replace it easily? (I can eBay a bits model to transplant it)
thanks. timbo400 |

No solvent will help - in fact, it was the solvent that damaged the focusing screen, as you guessed. You're going to have to replace it, I fear. I know absolutely zero about K1000s, but most SLRs I know of which do not have replaceable screens only can be removed by taking the top cover and prism off. Someone will likely be along to give details. I learned a few things fixing cameras and one of the big ones was never ever get solvent near an SLR focusing screen or a half-silvered mirror. The other was do not poke shutter curtains with your finger. |

Acetone is among the very worst possible solvents to ever have near a camera - it will attack plastic, paint and leatherette, and it's not really good for your hands either. Throw the acetone away and buy a bottle of cigarette lighter fluid if you need a hydrocarbon solvent.
For cleaning mirrors, I use Kodak lens cleaning fluid first, and then just my breath to clean off the water marks.
To replace the focusing screen in the K1000, first you'll need a new screen; the easiest place to get one is probably another K1000. Once you have that, you need to pull the top cover and prism off of both cameras to get the screen out. I'll be happy to send you some sketches if you would like them. |
