View Full Version : Canon EOS 350D view finder debris?

Hi all,

Last week I finally entered the wacky world of the digital SLR by purchasing the 350D (with kit lens).

Today I notice a black spot through the view finder. This spot is an irregular black mark. I checked the lensing and mirror and couldn't see the culprit. I'm left with the notion that there is something on one of the viewfinder elements... but that's all sealed up surely?!!


Anyone seen or heard of similar problems?
I'm not sending the damn thing back as this doesn't have an impact on image quality, its just rather annoying.

take a lint free qtip made for optics and rub the af sensor on the inside of the camera on the ceiling above the mirror in one direction until the debris is loose. Then use a rocket blower to get it out the camera. End of story....

Thanks Johneric8,

You make it sound like a routine, like brushing teeth or taking out the trash :)
I will work out if I have the balls to start tinkering in the camera inards tomorrow.

Hmmm, you should not really touch the focus screen, especially with a Qtip, what a strange recommendation to say the least. It is etched and anything brushing on the surface can leave marks, leading to a replacement screen. Use a blower, but you may find the debris behind the screen, in which case if you have not removed/replaced a screen before, let a pro do it.

Yeah, I took my camera back to the store and the saleman recommended that I put up with it. If it was to get worse, I should send it for a service while its still under warrenty. I'm going to leave it for the moment, its really quite tiny the speck but when you pay the equivalent to $1400 for a camera you expect it to be bleedin perfect!

:(

Thanks for your advise guys.

I would expect the salesman to say that kind of thing. It makes life easier for the salesman.

I would ignore the salesman, take the camera and shove it up his...

Jokes aside, it's probably a used/refurb/demo camera. U pay your money, they charge you 30-40 percent more for the option of return...

My rebel was spotless. And never touch the viewfinder... it's a very fine piece of plastic with delicate etchings that are easily scratched.

My 350D had a spot inside of it too. A nice sized one. It was behind the focus screen and no amount of blowing removed it.

Then one day I picked it up and it was gone. But then a tiny super small one appeared at the top left portion of the viewfinder. Oh well....

To get used to them I figured I might as well name them and become friends with them. Then hopefully one day they'd die out of nowhere and disapear or something.

once again I have used this optics qtip many times with no scratching at all............It has worked perfect!! I only used it when the dust was not moving. You dont have to take my word for it if you dont want to. From my experience in cleaning it I see no need to worry about it scratching if you use gently strokes. Like I said it's worked like a charm for me everytime. I'm sure most people will say not to do it and I can dig that.......

Sorry to say Bob, that is what passes for customer service in the UK.

I love the picture of the phone box. You don't see many of that type anymore as they are usually relegated to areas of rustic charm or significant tourist interest. This one appears to meet neither criterion.

I had one in my 20d. The Giottos rocket blower sorted it out in a couple of gusts, thankfully. That's more than I can say for the dust on the sensor though.

I had two HUGE dust spots in my 20d's viewfinder, and my 5 year-old generic blower couldn't touch them. The rocket came today from B&H and got rid of every speck on the first try. GET THE ROCKET, and save any problems from actually touching anything in there. :cool:

...and got dust problems coming out of the ying-yang.....

nomatter how much you pay you will still get dust on or under your sensor....

the best you can do is to clean the top of the sensor well (copper hill method)

there will always be dust UNDER the low-pas filter...they don't exactly use a dust-free room to put these cams together....

too bad.....for some 6 gran they shoud offer better quality....eh?

they don't
