Hi everyone
I am having trouble cleaning my camera, when i look through the eyepiece i can see bits off dust, hairs ect, the outside of the camera is clean, so is the lense. So when i detach the lense and look inside the camera, the mirror & sensor appear to be clean.
So the question remains, where abouts is this dust and how do i clean it.
My camera is a canon 450d.

Any help would be appreciated.
Cheers
Eddy

Sounds like it's in the viewfinder.
If you're not comfortable attempting to clean that area, there are businesses that can clean it for you, at a cost.
It won't affect the pictures, though I know it can be annoying.

Depending on how much of that stuff inside the camera, you may want to clean it out properly, including the sensor. I don't think I would want hair getting into any of the mechanisms.

I tried cleaning my viewfinder in my Canon 1000, what a catastrophe it turned out to be. I was missing a small section of the frame from the manufacturer, so when I went to clean it, it fell out and it did not take much to scratch the living daylights out of it.

I took it to a service tech, the viewer was around $70.00 to replace due to the scratches, but while the camera was there I had the sensor and unit cleaned. All up it cost me about $150.00. The camera was full of dust and sand from frequently changing the lenses. I learnt a lot from talking with the tech who was very helpful.

Cheers

Colin

on the subject of dust bunnies, my 1000d seems to do a good job of keeping itself clean..Atleast once a week even when it hasnt been used i give the lenses a good clean both ends, and give the sensor and mirrors a job blow.. but when it comes to my old kodak Z7590 being a fixed lense it has enough dust bunnies for some shots to resemble a snow-dust storm on the clearest of days! would the lense be removeable to allow the removal of the dust? there are a few lugs on the lense that look to be there to remove it..where would a suitable tool be found? i'd say it'll be similar to a grinder wheel tool semi circle with lugs on it to suit?

Thanks guys

Sounds like its the viewfinder then. Probably should take it to a service tech too & have it professionally cleaned.

Easiest way to tell if it's the viewfinder or the sensor or the lens is to do the following:

1) change lenses - if marks still in same place it's the viewfinder.

2) Shoot a picture of a uniformly white surface if marks are in the photo its either the sensor or the lens (go to point 1 above to test this)

Basically all camera viewfinders end up with crud in them always have since forever and probably always will. The good news is that viewfinder dust will not be in the photos - it will just annoy you. Trying to clean it MIGHT just mean it ends up transferred to the sensor by floating into the body that has this nice charged dust attracting surface (sensor).

If you're careful and mechanically minded - you can have a go at cleaning the viewfinder but be GENTLE or things may break and it'll cost more to be fixed. I have cleaned my film SLR's a few times BUT I will be less keen to do the digi.

Sometimes it's best to let the dust bunnies peacefully coexist in your viewfinder instead of trying to evict them. Some people can't handle that but sometimes the cure is worse than the disease.

CP - be carefull re the Kodak - a number of non SLR cameras actually have the sensor and the main electronics units AFFIXED to the rear of the lens unit. Many modern "compact" cameras are not suitable for "repair".

Talking to say Vintech or Camera Clinic in Melbourne (2 good camera repair mobs when I was in my camera store) may give you an idea of whats possible.

The cost of cleaning the Kodak fixed lens cam would be much more than what the camera is now worth...

Agree Teckert - however a quick call to the repairer might give CP the answer he needs re those "lugs" because it sounds to me CP is thinking of removing the unit himself. I would only do that if I could afford to have the camera U/S if it goes wrong. smile

Thanks DaveM i gave that a try, so appears that is the viewfinder and your right about being annoying to look through.
Pictures are still coming out relatively clean, thats the important part.
Cheers
Eddy

Yep Eddy - if you're seeing spots through the eye level viewfinder, it's almost always the viewfinder, sometimes the lens but you can't see spots that are on the sensor because it's not in the light path in ole fashioned viewfinder mode. If you are composing via live view (which IS showing what the sensor can see - then a spot on the screen MAY be from the sensor.(or a dicky screen or the lens etc but not in the viewfinder) wink
