LIGHT SEALS & MIRROR FOAM These are internal rubber pieces that, like the oil in your car, need periodic replacement. Varying with conditions they need to be replaced every 8-12 years. Like lubrication you cannot tell from the microscope camera cosmetic condition anything about the light seals and foam as time is the biggest determining factor, not use or handling. This is the most common flaw and the easiest to correct though the standard charges are still in the $75.00 + range.
BRASSING This is where the finish is worn away to the point that you can see the underlying brass. The degree of brassing is another clue to the use and care of the microscope camera. Though common on painted finishes brassing can be avoided by preventive measures such as leather washers around the eyelets. If you see brassing to the point where the l itself is worn AVOID that camera as the structral integrity of the casing has been compromised. Light, mild brassing on painted finishes is nothing to be afraid of as even limited, careful use can produce this.
