If they are deeply stuck inside the focusing screen, there is nothing much you can do.

Im not sure if camera bodies with no interchangeable focusing screen can still remove it, but Im afraid not.

Only way now might be try blowing from the edges of the focusing screen and hope some of the air goes in and blows it away.

And you sure you checked that the dust bunny is not sitting on the mirror?

Thanks YiP, yeah it's definetly not on the mirror...

Adam - which camera are we talking about? IIRC you have a D200. Is this happening with different lenses attached?

A month after I bought my camera, I saw a hair in the viewfinder.
I realised that it is on the focussing screen, so tried to blow it off, didn't work, so I used a brush, then a tissue.
Oh no, from one hair, to many black specs. But I lived with that on for more than 2.5 years years now.
If you can't clean it, you can always buy another focussing screen and install it yourself, or get the technicians to.

There's instructions somewhere on the Katz Eye website showing how to remove/replace focussing screens on Nikons - strictly speaking they're not "interchangeable" but they're not very difficult to remove.

I've got dust in my viewfinder too.

I found it annoying for a while but now hardly notice it.

OK just did it.... removed the screen as per the link above..... cleaned it all up with my sensor cleaning kit and walla..... too easy, although a couple of the supposid dust bunnies are actually small marks on the fosuing screen :shock:

wich is wierd ive never touched it. maybe manufature fault??
Ahh well the annoying ones are gone......Cheers for the help guys.

Adam,

There are in fact meant to be some "marks" on the focusing screen.

You should be able to see some very faint lines around the centre horizontal and bottom vertical areas, for instance.

Ok, yep i saw them but these arent really straight lines but more like a scratch, you can see it faintly through the viewfinder if you look at say a clear sky.

I just wanted to revive this post to say that after much annoyance at a hair in my focus screen, I decided to take the plunge and have a go at removing the screen and giving it a spring clean.

The results..............

It is obscenely easy to remove and the whole process can be done in about 2 minutes. Just thought I would share the "tools of the trade" especially after some of the horror stories. I used a matchstick to unclip the whole thing, a good sturdy one with no splits in the end, I hoped that if I slipped then soft wood is better on glass than metal and luckily I didn't have to test the theory. It worked really well.

I didn't manage to remove every single speck however I did get rid of all the hairs which were the major annoyance.

Does anyone have any suggestions as to how to remove the little specks?

So if you have 2 minutes, a steady hand and are seriously jacked off with the lines in your viewfinder, sit down in a quiet and dust free place and get cracking!

Thanks

Ed.

Ed,

What camera was that you removed the focusing screen?

Can you please explain the process in the removal and resintalling the screen??

by **adame** on Sat Oct 28, 2006 1:22 pm

Ed, I managed to remove 99% of the tiny specs i could see through my viefinder.... utilising my rocket blower and PEC pads, Very happy with the results... simple proscess indeed

by **edneeves** on Sat Oct 28, 2006 1:39 pm

I have a D70s

I would explain it myself however it is best done on the link further up in this thread. It also has pictures so its pretty foolproof.

This is the link

I still have to perfect the cleaning technique but you really will be surprised how easy this process is!!!

Is that a Giotto Rocket Blower? If so which size do you have? I have to say that my blower isn't the best in the world!

Yeah mate a Giotto rocket blower.....to be honest im not sure about what size.. :roll:

what i also forgot to mention is that i used my sensor sweep brush wich i got in this kit.

by **gstark** on Sat Oct 28, 2006 1:51 pm

Ed,

Most of us have the large, family size Giotto blowers. The photographic equivalent of a portable wind machine.

The blowers that you see in camera stores are merely generators of a light breeze, by way of comparison. BTW, could you please take a moment and update your location in your profile to something that is both more meaningful, and in compliance with the rules as per our FAQ?

Done!! No excuses for that either, I have been here a little while

I think I need to visit eBay and get some purchases going. The blowers don't seem to be expensive either so the accountant shouldn't be able to have too much of a fit!

LOL
Guess what...

I was too curious to try cleaning the focusing screen on my old camera which had big piece of hair inside, had a try on the F80, and.... I broke off the clip retaining plastic... :shock:

The plastic might be too old to apply force on... now, im left with a crying face and a none functional camera :cry:
