We use our digital equipment up to 5 to 10 times more than our film cameras, we have the facility of view and delete. When we had a roll of 36 film we were careful what we took images of and as a consumer the roll would last for at least three birthday parties.
Today with our digital cameras we take up to 100 or more images at the one birthday party. This creates wear on the unit.
Professionally used equipment
Should be cleaned, serviced and maintained every year. They are tools of your trade and they do need to be serviced and maintained to prevent break downs.
Consumer units
Depending on the usage. General recommendation is every second to third year. If you are a high usage consumer perhaps every one to two years.
SRT
Shutter release time. Most cameras have a shutter counter in them. Each time the shutter unit is fired the camera keeps count. This is a good indication of the type of service your equipment will require. If the camera has a high SRT (100,000 or above) the unit may require a full clean and service. The technician will inspect the cameras major moving parts for wear. If these parts show sighs of wear we will recommend their replacement.
A low shutter release count the equipment may require a basic clean and service and preventative maintenance.
A high shutter release count the equipment may require the major moving parts to be replaced.
