Canon EOS 5D Dust Problem
There has been an ongoing discussion at Canon EOS 5D forums regarding dust found in the Canon EOS 5D viewfinder. Below is the sample of Canon EOS 5D viewfinder with dust (not the sensor dust) that sits inside the finder and can not be removed with usual cleaning technique
One 5D user also has compared his experience with dust on EOS 5D and EOS 300D:
“In over 2 years I have had 0 issues with dust in the 300D viewfinder and also I have only ever had to blow dust of the CCD on 1 occasion. For the 5D in 4 weeks I have blow cleaned sensor 6 times and blown dust off focus screen almost every day”
By putting all input in similar threads in other photography forums together it seems to be fair to say that the 5D has an issue with dust in the finder. Let’s see if Canon will react on this…

Well, I have had my 5d for just 4 weeks. When I changed the focus screen to an Ee-d grid type I had a white powdery dust fall onto the mirror when I opened the screen cradle, which I blew off with a rocket blower holding the camera face down. As soon as I put the new screen into the cradle and locked it off, high static activity pulled loads of debri onto the surface of the screen, or into the prism area, and it just won’t budge via blowing. In fact it just makes things worse. I now not only have dust in my viewfinder, but dust on the sensor that can’t be moved by just blowing. I have contacted Canon’s help department about it and hae had little response. I don’t just want to be told to send it in for cleaning and wait 6 weeks for its return, I want some kind of acknowledgement that this is a problem they will deal with as a matter of urgency and at least recognition that they will do so. It’s not much to ask considering the price of the camera and loss of enjoyment. My comment here is to warn others off buying this otherwise brilliant imaging machine untill Canon have sorted out their quality control.
Hello,
I have had the same problem with my Canon 5D and also sent mine in to Canon for a cleaning which took nearly a month for it to be sent back. However, it doesn’t take much to get dust back onto the glass. I have learned not to clean it and basically live with the dust though it is virtually impossible to change out lenses and not get dust in there again despite how moist the surroundings might be, I have learned to improvise my images. The worst scenario with the dust specks is in a bright blue sky if you shoot landscapes. However, I tested this with and without using a tripod and noticed when I hand-hold the camera shooting the same scene there are fewer specks. I guess the slight movement from hand holding is just enough to make those annoying specks less in focus. Sounds strange but it is the only thing I can think of. You may have to sacrifice your shutter speed and ISO settings when shooting hand held but luckily the resolution of those 13 megs does not depreciate the image with noise that you would otherwise get with a lower res DSLR or of course a high-speed film. Until Canon fixes this issue, this is one way around it. Hope this helps.
just read about the guy with dust problems in view finder i,v got the same problem in my 5d tried the same things to no avail cost me a small fortune in cleaning products nothing works i,m not getting the proper benefits or enjoyment out of a so called top camera as i should be lets hope they can sort something out soon!! such a small problem to sort out don,t want to be sending camera back for cleaning every week?? what a waste of time could be out taking pictures!!!
Keith..I have exactly the same problem as yours and it seems that Canon would not react on this problem anytime soon.. I think They might just going to release the new camera replacing 5D with Integrated Cleaning System..
Thanks for the reply, but I don’t see that an integrated cleaning system on an upgrade of the 5d dealing with dust will help with what is clearly manufacture debris problem and one that seems to originate from the viewfinder, mirror or prism housing area. It seems to me that Canon need to spend more time ensuring clean, laboratory conditions, manufacture of cameras in the first place, before bringing out new models. In the UK we have a sales of good act that protects purchasers from this kind of shoddy workmanship, (for that’s all I can put it down to) and which I will probably have to evoke if no response is forthcoming from the Canon management soon. I hope you can resolve your problem too because it isn’t how Canon should be doing business with us if they want photographers like us to remain loyal to their cause.
I just couldn’t figure it out. I saw the dust and immediately thought it was on the sensor. After blowing, I realized the dust wasn’t on the sensor at all. Dare I say that I’d only had the 5D a few months and saw the dust while on my first vacation with it? It was only last night with the camera club and today while reading the posts above that I realize there is no easy solution. You would think that for the amount of money paid, Canon would be on top of the problem and forthcoming with a solution other than sending the camera off for weeks.
My 5D is about a year old and full of viewfinder dust. It appears to me it is collecting on the pentaprism behind the viewfinder eyepiece where you can’t clean it without disassembly. Blowing with air just sends MORE dust up there. This is very poor engineering……. it wouldn’t take much thought to design a simple seal. Quite disappointing.
My 5D was only 3 days old. I’ve got more than 10 little specks of dusts accumulating in the viewfinder. I regret blowing air into the viewfinder, which creates even more black cruds appearing. It’s sad, but I have to live with it…
Hello,
Does anyone have any idea if these little specks on the viewfinder of the 5D can affect focus in anyhow??? i’ve compared the 5D ( i only brought it a week ago! ) using 24-105mm lens with a Sony DSC-R1 (10 mega) taking the same shot on tripod, the clarity and sharpness in the sony is much better than the 5d!
i have had it four about four hours didnt even use it really and it has dust init!
MItch
same problem I am going to look into the legal position been with canon for years no problems till this.. this isnt performing as it should at all.dust in viewfinder and on sensor barely had camera 4 weeks constantly having to clean
never had dust like this in any other camera
