Hi!
I returned from an outing to the Tana/Tanojoki river delta over the weekend and discovered that I had got rust on the hinges on my SF! The weather was splendid without a drop of rain, and the only thing I have done to them is to rinse them under (clean) water to remove some dirt and dust.
I see there is a part of the hinge of the SF that exposes its shiny metal inner workings to the elements. I thought such binocular hinges were supposed to be made of magnesium, or at least stainless steel or some other material that shouldn't rust so easily? I find this quite weird, especially for a binocular that purports to be waterproof...
Question is: could this rust be dangerous to the binocular, or is it just surface rust that I don't have to worry about?
I also attached a couple of pictures of the discolouration on the binocular armour, which has been reported by several other SF users, but which has been the object of some contention on this forum.
