Focusing Screen Dust!

Lennardinio · 2010-01-28T14:16:07+0000

Hi I noticed earlier a rather annoying dust spec on my focusing screen. After some ill-advised self attempts at cleaning it with air blowers and lens cleaning brushes, I am now left with a lot more dust there which is really annoying. Obviously I appreciate that it won't show up on any images but I would like to get it fixed all the same. So my question is... where is the best place to get the focusing screen cleaned and how much should I expect to pay? Many thanks in advance. Andrew

If the K-m has interchangeable focus screens like the K10 and K20 you can easily remove the screen with the correct pair of screen-removing tweezers as seen in this photograph.. There is also a move on youtube showing you how to do it. You can then puff/hoover your screen and the bottom of the prism. Be careful though, the screen will scratch almost as soon as look at it.

Using 50 year old cameras has taught me to just live with it. As long as the final image is OK, I leave well alone.

Why's it a problem?

I just find it annoying, that's all. It's just me being pedantic. I will try and live with it for a while and see if I get used to it.

Thanks for all the comments.
