Default Help with spot on sensor.

My Olympus E-520 has a Black Tiny spot on the sensor. ( I think )
I tried different lenses and cleaning the mirror. No LUCK
So I am ASSUMING it is on the sensor.
Luckly it is on the Very edge of my pictures.
Any Ideas if it is dirt or something else ??
What is the best soloution for a FIX.

Thanks in advance

It could be a bit of dirt. Do you have a 100% crop of that side of the pic?

Assuming it is dirt and not hot/dead pixels on the sensor, you can try using a blower like one of these to get that speck of dirt off your sensor.



See your owner's manual on how to pop up the mirror to get access to clean the sensor.


If blower doesn't work, then a wet swab sensor cleaner might be next.

Thankyou for the Reply dr_spock .
Yes the image is 100 %
It is very noticable through the viewer.

By viewer, do you mean the optical viewfinder or the liveview on the LCD? If it show up in the optical VF, it is not on the sensor, and could be a bit of or something stuck to the side of the mirror box. If it is the live view on the LCD where it shows, then it is on the sensor, but in that position, it probably isn't worth worrying about.

It is very noticable on the Optical view finder.
I cannot see it on the Live View. I will have a closer look.
If it is NOT on the sensor that is encouraging.
If it is on the sensor , in that position as you say Its not worth worring about.
It is just a little annoying seeing that dot in the Optical VF

Thankyou.

Something doesnt sound right here.
If its on the image the dust blob is on the sensor, if its in the viewfinder it could be on the mirror, or in the viewfinder. Never the twain shall meet.

If you want to insepct dust on your sensor the easiest way is to set aperture to the highest f number your lens has, focus to infinity then snap a shot of a clear blue sky. Open in PS or equivalent and bump contrast. The dust blobs will show themselves. example below, I use this to not only see if I need cleaning but also to locate the problem spots. If the blob is top left on the image the blob is bottom right on the sensor. This guy needed cleaning and took a little time but can be done at home.
