How often should a classic 35mm camera be serviced?
Cameras are not like cars. They do not need a yearly servicing. With normal use, a classic 35mm camera should be serviced about every ten years. But, if you have exposed your camera to an extremely harsh environment, such as beach sand or water spray, it would not hurt to send it in to your local repair shop for a CLA (clean, lubrication and adjustment). This is a preventive measure to insure that no damage, such as corrosion to electronics or abrasion to bearings, is taking place inside your camera. Of course, better yet, try to keep your camera away from water spray and sand. Buy a cheap plastic throw-away camera for those rafting trips and leave your good 35mm SLR in the car.
