Forensic photos of ED-X2 104mm
These were taken so that a remote buyer will see ahead of time "worst-case" dust and "imperfections" in the lens, even though they're not readily visible to the naked eye under most lighting conditions.
Lens dust has been blown with a bulb and dusted lightly with a soft lens brush - not cleaned (with fluid) or rubbed.
Camera lens is set to f/1.4 and overexposed two stops to make the dust visible.
