TΙ ακριβώς σημαίνει η προδιαγραφή IP53 που φόρεσε η ΟΜDS στις ΟΜ1 κι ΟΜ5 και στους νέους φακούς ?
IP53
With the new
OM-1 and OM-5 camera bodies launched by OM System, and several of its new lenses, the IP specification is now IP53.
The ‘5’ means the product is ‘Dust protected’ but this is one down from the ‘6’ rating of ‘Dust-tight’. Rating 5 means: “Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the safe operation of the equipment.”
The second value, ‘3’, means that there is protection that can cope with water spraying onto the product. Interestingly, the next number up the protection performance ratings (4) refers to splash-resistance. It seems that neither Olympus, nor OM System have yet achieved this level of IP rating for water resistance, despite the widespread talk of ‘splash-resistant’ bodies and lenses.
The test regime to achieve a ‘3’ for liquid ingress is: “Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect, utilizing either: a) an oscillating fixture, or b) A spray nozzle with a counterbalanced shield. Test a) is conducted for 5 minutes, then repeated with the specimen rotated horizontally by 90° for the second 5-minute test. Test b) is conducted (with shield in place) for 5 minutes minimum.”

Summary
In conclusion, while the OM System OM-5 might not be the most exciting new camera we've seen in 2022, it retains many special attributes. The fact that this didn't grow a DSLR-shaped grip is actually kind of a blessing in a time that cameras are getting bigger and meatier. It's nice to have this kind of retro-styled option that's on the smaller side, has a long list of features, and that retains and furthers OM System's dedication to weathersealing.
Updates from its predecessor without adding weight or size include:
- Faster processor
- Starry Sky AF, LiveND and Handheld High-Res Shot
- IP53-rated weathersealing
- Improved image stabilization
- Reinforced bottom plate/tripod socket
- Native UVC/UAC webcam support
- Vertical orientation video shooting
- Uncapped video recording
It's clear that these minor updates won't make Olympus OM-D E-M5 Mark III owners run out to their local camera store to buy this as an upgrade. But as a camera for new shooters looking for something small that can do it all, the OM System OM-5 has a lot to offer.
