The OM4Ti stays simmering in the oven for one hour with its back opened. The OM4Ti is filled to the top with electronics, circuit boards, and plastic seals. The camera is taken out of the oven with kitchen gloves and we try the shutter speed tests. The tester does not function because of the high temperature. After cooling down for a few minutes the tester functions again and we ascertain that heat has no effect at all on the camera.
All shutter speeds stay within their tolerances.
The sandblaster asks us if this is another expensive one and hangs it by its straps in the air outlet of the blasting room, where it stays for two hours. At Olympus TD they say that the Dutch are sloppy with their cameras. The number seems to be a lot higher than in any other country. We deliberately abused our 4Ti with dust to check if the camera is sealed well against dust and water. It is, because after the sand, dust, and dirt test the OM4Ti still functions well.
