Camera cleaning
« on: July 30, 2014, 02:31:00 PM »
Hi all, I have been trying to remove some dirt spots that show up when I look though
my camera's eye piece, the dirt is not in my lenses as it is still there when I
don't have the lens on i have tried everything to clean them with no joy any advice.

Cheers Geoff

 The good news is that if they show up through your eyepiece then they're not on your sensor.
 (I'm assuming DSLR here.)

   Could be on the mirror, carefully use a blower brush. The mirror is front surface coated and VERY easily scratched.
   Could be on the fresnel, this is on the underside of the pentaprism and is visible if you look into the camera through the "lenshole". if it's a posh camera it may be possible to remove the fresnel, have a look in the manual (It's in the attic with the boxes!)
   Could be under the eyepiece. Remove the eyepiece, there may be a trick to this, again check the manual (It's in the bin.) and go at it with the blower brush.
   If all this fails, learn to live with it as it doesn't affect your pictures and in all probability it will dislodge itself and fall somewhere less visible (But infinitely more damaging.)

I had something similar with my Pentax - specks on the focussing screen. This link shows how to clean that. I found it scary to think about doing, but easy in practice once I plucked up the courage to try it.

Your camera might well be similar, or maybe you'll find specific instructions on line.

Good Luck.

It is probably dust on the focusing screen OR between the focusing screen and prism.  I have replaced my focus screen on my Canon 450D, it is not hard.  It was all clean when I was done, now I have dust again.  None on the sensor, so I am ok.
