I think my 7D sensor is dirty.

I notice some dirt specks on the mirror. Should I start cleaning the sensor?

can I clean off the dirt specks on the mirror using the lens pen brush ?

The mirror and the sensor are two separate things . Dust on your sensor will show up on photos of the sky shot with a small aperture .

Is it safe to use the brush to wipe off the dirt speck. They are light static dusts.

+1 for rocket blower for loose dust.

If that doesnt clear it its time for wet cleaning (which can either be done by a professional or yourself if careful)

Copperhill method is one method
