The specks are in the lower left, looking into the front of the camera.


I guess the people who replied meant to say that the dust is in the bottom
right *when looking at the camera from the rear*. The only trouble with
this is that you would not be able to see the sensor (to clean it) without
the aid of a mirror ;-)

Adrian,
So far, I get: "look(ing) into the front of the camera..." , "when looking
at the camera from the rear"... I'm confused... very confused ;-)
Please, when looking at the sensor to clean it, then where? Thanks
Marcel


It's in the bottom left, as you look at the sensor to clean it.
The lens both inverts and reverses the image on the sensor; as you
look at the sensor *from the front*, you're reversing it again, but
not inverting it.
Imagine this: use a piece of frosted glass, and see the image from the
lens from behind the glass; this is how the sensor sees the image from
the lens: upside down, and left for right. If you now move in front of
the glass, the image is still upside down, but it's not left for right
anymore.
Easy. :-)
