Help! Coatings on Victory SF being... weird? (3 Viewers)

You beat me to it.
Never make a simple thing complicated …… you’ll wear your brain out.

I've got a Dialyt 8x30BGAT*P dating back to 1990. The eyepiece lenses are quite different in colour. No differences in optical performance. These things happen from time to time due to minimal temperature variations in the coating process. Never bothered me.

Ooook, another little update.
I got a call from the shop that they had response from Zeiss. (They had sent them photos and a description of the case)
Zeiss wrote (based on the photos) that they had never seen such an extreme difference in color in objective coatings and asked if it was possible to send them the bins for inspection.
So I brought the bins to the shop to be sent to Zeiss. Sadly they didn't stock a replacement pair and I'm now without a Victory SF. No big deal tho, as I luckily own other pairs of bins (Just a little sad to not have my "new toy" around to play with
)
Now I'm even more curious to hear what Zeiss has to say, but it might take a couple of days/weeks until I know what's going to happen.

I believe they'll change the objective lens. I also believe they'll check the whole binocular very carefully, so you'll end up with a perfect binocular ...

Oooook!
I can finally report back to all of you about my SF.
So Zeiss replaced the objective lens of the "green" side.
They also explained that they normally wouldn't change slightly differently colored lenses, as it is normal (as you all suggested and I also suspected) to have minimal variance in the thickness of coatings, which results in the lenses reflecting different colors whilst not affecting performance.
However, one objective being completely green was weird even to them and they replaced the objective unit free of charge.
I'm very thankful for the "fix" and the nice explanation, top notch service there!
The result? The objectives are now both different shades of red, I got the peace of mind that there's 100% nothing wrong now and I have a GORGEOUS binocular that's quickly becoming my favourite every-day birding bin.
Happy birding everybody and thanks again for all of your responses and helpful comments!
