[QUOTE="mooreorless, post: 1303864, member: 28262"] Hi Ed,Sorry I didn't see this until this evening. When I bought my 7x30SLC is was supposed to be WP. You are right this binocular doesn't have the glass plate in front of the objective, so I guess it is just water resistant.:-) I don't imagine the 1991 model 8x30 SLC was phase/coated either like mine. The picture I have of the 1991 model doesn't have the glass plate in front of the moving objective. I returned my pair to SONA in 2003 and at that time I asked if I could upgrade to phase/coating and they told me only the full size SLC could be upgraded to phase coating. Zeiss is supposed to have come out with p-coatings in 1988, so I would think it would of taken a while for the rest to catch up. Regards,Steve [/QUOTE]
