Marty,
The very first LLL replica 8E lenses had blueish coatings (as can be seen on the front element). Shortly thereafter, as far as I have seen and heard, amber front coating was used. So if the later(est) replica 8E lenses increased shadow detail, where were different coatings employed to allow additional blue light transmission.
Lastly if somehow more blue light transmission was somehow employed, wouldn't we see additional bias towards a cooler rendition in these lenses? From what I've seen the earlier ver 1 lenses were on the much cooler/blueish side than possibly later lenses. Just trying to get a handle and understanding on all this. Thanks.

The amber coating is the “single coated version”. The blue/purple coating is the “multi-coated” version.
The original 8E had single coating but the replica was offered in both versions.
The higher shadow detail is more of a function of the way single coating on a lens renders shadows (especially in B&W) and is due to the lower light transmission and veiling glare. This light scattering can give enough exposure in the shadows to help bring out any details.

>>>>but that's what is a bit confusing for me. Namely the amber single coated replica lenses (the earlier ones released after they switched from the purple/blueish coating to amber) were reported to have been improved upon recently with better shadow detail. Yet these recent lenses also still have amber coating like the earlier ones. Therefore since they didn't revert back to purple/blueish multicoating, how did they improve shadow detail in the recent amber coated lenses vs. earlier one released (both having I presume single amber coating)?

Until someone has multiple LLL lenses and posts pics of identical subjects

I'm interested in the impact of a multi-coated filter over a SC lens such as our LLL lenses.
With a MC filter in front of a SC lens, does this mean the rendering is more like a lens with a MC coating, or are there still SC characteristics?!
thanks

The coatings being the same colour does not mean that they are the same. And ‘blue’ is from 450-495nm, and coatings have partial effects on colour transmission.
Without the exact formulations, you can’t tell what they have done, even if you have multiple lenses displaying the different characteristics.

So, do you have any idea of HOW to distinguish the 1st amber version vs 2nd version amber?
Mine is amber coating also, serie XXX500, received September 2020 if it could help.

If you look at the prototype lens LLL sent to LHSA, the lens has a bluish color coating. If your source is reliable, all the RF forum buyers should have the later amber coating.

As far as I know the info is pretty accurate.

Here are some more pics of the lens..
I was initially skeptical of this claim, until I went through Mr. Zhou's Weibo blog and checked the photos he reblogged of some of the first V1 lenses delivered to the Chinese market. All those lenses, which were delivered months before anyone at RFF got a production lens, indeed do have amber coatings.
My lens, which I received in early May 2020 some months after those initial lenses reached their owners in China, has a bluish purplish coating. I think I was the second or third person at RFF to receive a production V1 lens.
The second round of amber coloured coatings came out some months after I got my lens.
In response to the poster above asking about multi-coating, that never happened. All versions, amber or purple, are single coated. And I suspect any differences in rendering, while definitely there, are subtle rather than stark

Are there many black LLL 35mm lenses around?

Mine (F8+There, 500140) is black Erik. But I'll have to recheck if it has amber or blue coating!

I wonder if the amber coated lenses initially released in China prior to your bluish purplish coated lens are any different than the amber coated ver 1 lenses most of us received here on RRF numbered xxx/500? Then after these amber coated xxx/500 ver 1 lenses, seemed to come the amber coated V2LC amber coated lenses available from various retailers with all lenses up to this point having uneven spacing of the aperture. Whether there are optical differences between all the above versions, its hard to determine without direct testing.

If Emile's info is correct (and it sure seems to be)...
Amber coated lenses initially released in China = original ver 1 (1st coating) Amber was the highest contrast..
My bluish purplish coated lens and others = Then the Purple (2nd coating) came out and lowered contrast a tad..
Amber coated ver 1 lenses most on RFF received numbered xxx/500 and amber coated V2LC = Then later..2nd Amber coating came out..and contrast was lowered even more.
And that continues to be their coating this day.

My lens, a 164/500 is amber coated - 1st Version.
With all the contraversies going on here, my lens is slowly becoming a cult classic.
Keep em' coming boys...
Now, I'm off to shoot me some negs - wait, it's almost midnight. Dang it!
