Camera is a 20D so no live view, but I found it on some images, checked at f22 on an out of focus plain wall and it is there.
Test in Live View, using F22 aperture. If the hair appears on the camera's LCD, actually it is in the sensor.
There is a hair in the lens, looks fairly deep in, possibly on the image stabiliser element, so I tried another without the hair and the L is still on the image!
Not to ask the stupid question, but have you tried another lens? Sometimes it's in the lens. Don't ask how long it took me to figure this out...
Hi Mt Spokane.
My hair in the lens doesn't seem to show up so far, I guess that confirms my observation that it is not on the rear element.
Yes, a hair on the rear of the lens will show up and look awful.
My question was if I see crud on the top left of the picture am I correct that it is the bottom right of the sensor I need to look at? Bottom line is this only shows at smaller apertures and this camera is mainly used for workshop documentation with flash.
