The D300's sensor (the area

Any dust or dirt that gets into the

mirror box (behind the lens) seems to

ultimately work its way and attach itself

Nikon bodies where the frame holding

the sensor came right up to the imaging

area, there's enough room in the D300

off the imaging area when cleaning.

Moreover, the D300 has a self-cleaning

sensor, which uses a shake technique

to remove dust automatically. See
