Have an NX8 4-32 F1 Mil-xt. Site says 28.6 oz. My [cheap postage] scale measured 30.08. I should have also weighed it on my powder scale for comparison but didn't think to. Anyway, hopefully their number is right and mine is over because that means everything in my pack is actually lighter! Maybe their weight doesn't include lens covers, yet they are included and are already installed.Although I've heard real world NF weights be all over compared to listed weights so maybe you have a light one?
