Brock:
I have 2 8x32 SE's, one is a 504xxx and the other a 550xxx .
Both have just a plastic sticker with ser. #.
They appear identical except for coatings, the 504 has a blueish cast when
light is reflected off the objectives, and the 550 is more greenish.
When do you think the eco-glass, lead free appear?
You know, these are just a beauty to look through!:t:
For me, optimum diopter setting is identical, near 0, as are other Nikon premium optics I have.
Nikon really does have excellent quality control in this respect.
I have 20:20 vision without glasses.

Jerry,
Thanks, now we know when Nikon updated the coatings (2002) with the 505s. Your 504 coatings look like my 501's.
Too bad you aren't sensitive to CA or you could probably see which SE had the lead-free glass.
According to Nikon, they changed over to lead-free glass in all their optics in 2002, which would mean my 505 SE is lead-free.
If I were sensitive to CA, I would see CA closer to center in the 505 than I did in the 501.
That's the "telltale sign" I've identified in lead-free bins, and IMIUUS (in my "idle, uniformed/unconfirmed speculation"), that's the chief driver behind why the alphas and some betas are using extra low dispersion glasses in their bins now.
Too many complaints about CA in their previous models after switching over to lead-free glass. (I actually do have some scientific evidence for this but I have to work this weekend, so I don't have time to dig it out, but will when I get a chance).
Count yer lucky charms, lad, you've kissed the Blarney Stone and can't see CA. Once you see it, it can become as distracting as a "floater" you can't ignore.
Curiouser and curiouser... your 504s (2001) have a number sticker like the 550s (2007/8), and my 505s (2002) have a painted serial numbers under plastic like the 501s (1998), as well as the three 10x42 SEs I tried and two 12x50s I've owned. A real Gordian Howe knot, that one.
I was working on IUUS about how the paint Nikon was using on its 550s serial #s was found to have lead in it, because although the parts were manufactured in Japan they might have been assembled in China (isn't everything now?), and China doesn't have lead-free paint, as we know.
Since Nikon switched over to lead-free glass, they wouldn't want to use environmentally unfriendly lead paint! Thus, an explanation for the stickers on the 550s. Case closed.
But now that I've learned your 504s also have stickers, that shoots my speculation to StoVoKor!
Well, no time to delve into this mystery further, so I'll leave "The Curious Case of the Missing Serial Number Paint" to the Hardy Boys to figure out.
Hope it stopped snowing out there!
