Smear Away.

It's not a good feeling when a simple light brushing of a camera sensor to remove some minor bits of dust results in grease (from the shutter mechanism??) being spread all over the sensor. That is what I did to my Nikon last night.

Three swabs, numerous drops of 'Smear Away', a lot of frayed nerves and £36 later I think the sensor is clean again.

Lots of photos tomorrow will tell me one way or another.
