Hi

Help need regarding dark spot on top of image.

When i look thru the viewfinder, it does not show up and when i use my kit lens, on white sky its shows a small black blurry spot at the top when i load the image into the computer.

When i use my 50mm f/1.4, it doesn't show but when i stare hard enough i could see a faint black spot on white image.

Thot the kit lens was dirty and clean it together with my 50mm but its still showing. Is this becos the CCD is dirty and how do i go abt cleaning/rectifying it. Advise appreciated

tks :sweat:

I will post pics if i know how... :sweat: :eek:

Most probably is your CCD dirty.. dun worry try to use the blower kit to blow away.

I got such blur spots from my 300D recently too... I thought it was my lens, but realised that dust specks in lens will not show up on images...

So I flipped up my cam's pentamirror and used a blower to blow the CCD... it worked...

Hope this helps... :)

Never blow the CCD with a blower.

Just send in to Nikon Singapore for CCD cleaning.

Pardon me. What you did is a no no. You will ruin your CCD. Maybe it is really damaged. :dunno:

Mr Pok,

Ya the CCD will be damaged, unlike film where you get a new frame each time. With CCDs once dust gets in it stays there. I'd send it for professional cleaning. Don't DIY.

Hi!

1. 300D has a CMOS sensor. not CCD.
2. The pentamirror cannot be flipped. It's behind the focus screen. What you flipped was the reflex mirror.
3. Do NOT manually flip the reflex mirror. Use the sensor cleaning function to get it out of the way.
4. Using a blower (no brush) on the sensor is recommended by Canon (despite what the other say. RTFM before making others panic). be careful not to touch the sensor.
5. if the blower dont work, send it in. Canon charges $20 for a sensor clean.

heheh... pls pardon me for my lack of technical knowhow... yup, I used the sensor cleaning function to get the reflex mirror up... and yup, blew without the brush of course... so glad to know that Canon recommended this procedure too... for a while I thought I screwed up my 300D... but anyway, been taking photos after the the blowing... image quality not affected leh... phew.. ;p
