[QUOTE="kbouk, post: 1058814793, member: 20882"] TΙ ακριβώς σημαίνει η προδιαγραφή IP53 που φόρεσε η ΟΜDS στις ΟΜ1 κι ΟΜ5 και στους νέους φακούς ? [B]IP53[/B] With the new [URL='https://magazine.e-group.uk.net/pages/the-digital-om-system-olympus-om-1/']OM-1[/URL] 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.” Στη φωτό ακολουθεί η παρουσίαση των σημείων που το σώμα και ο νέος 12-40 ΙΙ έχουν τις απαραίτητες τσιμούχες [ATTACH alt="7FEC047B-3DA2-47AF-A6C6-BD1EE3CB4F68.jpeg"]204953[/ATTACH] Για την ενίσχυση της βάσης έγραψε σχετικά και το Dpreview , το πρόσθεσε και στην περιγραφη Source: [URL='https://www.dpreview.com/articles/2125228181/om-system-om-5-what-s-new-and-does-it-compete']OM System OM-5: what's new and does it compete?[/URL] [/QUOTE]
