Hello all im having abit of a probleme. Im very new to photography so please bear with me. Basicaly i some how got dust on the peice of glass witht the 9 focus points on, my dad tried cleaning it for me but its got all smear marks on with more dust. Can anyone explain how it should be cleaned? Also what items are needed to clean it as its quite awkward to get to. Or should i just get a shop to clean it for me? Please help

Thanks in advance..:bang:
 
Thats the focus screen and the last time I tried to clean one in a 400D I ended up making it around a hundred times worse and introduced a lot of mess. If it's really bothering you, take it to a shop to get it done but it's probably a waste of time as it wont affect your images.

I wouldnt advise doing it yourself, I took the entire assembly out and it was extremely difficult to get it back in correctly and even when I did the focus points didnt line up.
 
would it be worth using a cotton bud with something.. its quite smudged thats the thing thats bothering me..Thanks for the reply though.

Don't use a cotton bud. The focus screen isn't made of a robust material IIRC and will probably not take too kindly to an abrasive surface like that.

If it's really bothering you I would suggest getting it done professionally. Focussing screens arent removable / interchangable on the 400D IIRC so you're likely to introduce more dirt and dust into the chamber unecessarily, and if you make it worse then you're left with an even bigger repair bill.

Live with it if you can (Alot of people do!) but if needs be, I'm sure a camera repair centre will do it for a few quid :)
 
Whatever bits you decide to try and clean ......

DO....NOT....EVER....TOUCH....THE....MIRROR.......WITH......ANYTHING!!!!

This applies to all of you.

It is not like the bathroom mirror where you can squeeze your spots and wipe the pus off the glass with a wet flannel. Wipe your camera mirror and you'll destroy it. I tried it as an experiment with an old film slr. One gently wipe with a soft cloth and it turned it to dark grey streaks.
 
Dont worrie i havent. I will live with it, i looked again after and its not even that bad. I was just panicing and dont want to damage my cam .

I clean my mirror all the time on my 1dsm3 and my h3d, I take off the lens and seems half the dust in the room is in my camera body. I've used everything from the SensorScope system, Sensor brushes to a white cotton t-shirt I was wearing at the time. Your right its certainly not the mirror in your bathroom but unless your using some super fragile camera I dont know if its covered in dust clean it. I mean if you can clean a sensor/ir film then why not a mirror.

If your really scared you could send it off to your camera manufacturer to have it cleaned which I do once a year on all my bodies but dont see the point of waiting that long.

Best of luck with your cleaning then, and I sincerely hope you don't do any damage. But the glass covering the sensor is significantly more resilient than the mirror. Here is a picture I've just taken of an OM1 mirror that I bought used. For those who don't know, the Olympus OM1 was a pro 35mm film slr from the 70s, and quite pricey for the era. I'm sure the owner took the best of care of it. All the marks that you see here are permanent. The scratches - both horizontal and vertical shown here in just one corner - are also in other areas of the mirror, but I couldn't get a decent shot of them.
