With a topic like this I'm bound to cop a lot of flak but what I mean is... though Ruby is such a great lens to look at, they just aren't that good to look through. I may be in the minority here but I find the dull grey/blue tint does very little to improve contrast or even cut out glare and just seems to make everything murkey and..well, just plain dull :/
Also, after having worn my Ruby XX's for the first time I decided to give the lenses a quick clean only to find they streak and smear like crazy. Yes, I was using a clean micro bag but like +Red these things are HARD to clean. With much effort I've managed to get em near perfect again though now there's a couple of swirl marks that won't disapprear, which means they're more like tiny scratches! Granted they're so small you can hardly notice them.. but still. Is there a special art to cleaning ruby lenses?
I'm glad this happened with the XX's and not my Pennys, which I probably won't attempt to clean at all now after this drama.
