>>4283720If you ever actually read IP ratings, the highest standard of this marketing scam, you'd know that 0 cams actually gaurantee that dust/water will not enter, only that the camera wont shut off immediately if they do. The highest IP rating ever assigned to a consumer ILC is IP54 (leica m11). No W, meaning the camera is not actually weather rated. The OM1 is IP53.
IP5X:
>Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment.Dust can cause it to fail LATER, by building and causing a jam, accelerating wear, forming mud due to water ingress, or by being conductive in nature. Not during the test. A device is NOT dust proof until IP6_.
IPX4:
>Water splashing against the enclosure from any direction shall have no harmful effect, utilizing either: a) an oscillating fixture or b) A spray nozzle with no shield. Test a) is conducted for 10 minutes. b) is conducted (without shield) for 5 minutes minimum.In IP speak, no harmful effect means the device works during the test. If corrosion has started on an electronic part, or if your lens is now doomed to be fungified, this rating does not care. The normal highest water section of an IP rating, IP8, STILL allows immediately harmless ingress, and the depth and duration are manufacturer specified. Only IP9k is actually where I would begin to call your device waterproof, everything else is "insured against immediate failure and ok if you dry it out really thoroughly afterwards".
No tests are conducted while a man puts pressure on the body or uses buttons, wheels, focus/zoom rings, and the articulating screen
If you trust this marketing BS, there is a great chance your camera will immediately survive, because rainwater is freshwater and less conductive, and most dust isnt sand or metal. long term? camera manufacturers want you to buy more cameras. video of a nikolympony OM-ZrV in rain? It'll die, get glitchy, or fungify - later.
