Old canon porros question (1 Viewer)

Do Canon porros (non IS) from the 70's come with the lens elements blacked? I had to clean some recently acquired at auction and was surprised to find the objectives as well as the eyepiece elements all blacked. Outside of some early Nikon 8x30 8.5 degrees binocs, that the only 2 of the Japanese manufacture that have passed through my hands that have that treatment. I have no way of knowing whether that was standard fare or done after the fact at one of the cleanings/ adjustment the bins might have gone through. Further question- since I've not experienced any of the euro maker binocs, do any of them offer such treatment in the binocs? Regards, Pat

Pat, I have a pair at my office, but during Covid times I don't get there a lot. I'll check though next time I'm there. You mean blacking the outside perimeter of the elements, right?

b-lilja; That's correct. After opening to clean approx 200+ binocs, it's a pleasant surprise to see the attnetion to detail hat a couple of the makers used in their optics. If you have to open them up, best to leave them as is and not disturb the settings. Regards, Pat
