👉 The dial fluid, also known as the cartridge fluid or internal lubricant, is a critical component in many digital cameras and camcorders that operates within the camera's internal mechanisms, particularly in the moving parts such as the mirror, lens, and shutter. This fluid serves to reduce friction, ensuring smooth operation and longevity of these parts by preventing wear and tear. It also helps in maintaining the alignment and functionality of the camera's internal components, contributing to the overall performance and reliability of the device. Typically, dial fluid is replenished periodically or after extensive use to keep these mechanisms in optimal condition.
