That will be interesting to read if you do. 'Immersive' is definitely not my invention; I think it's a word used by a few other posters and yes I think it's more descriptive than just saying 3D but I suppose they mean much the same thing! After doing all sorts of routine tasks today in town I popped into the local dealer and had a play with a Leica 10x42 BN. Also great colours but looking through the wrong way round i.e. as a sort of minifying glass you could see the collimation was out. Still had the immersive effect!
I've heard the term immersive used a bit around here but it seems quite apt for these.
Careful about the 3D thing lest someone jump on it. Best to say "3D like".
I wonder how close my BR is to a BN? I've read that the Trinovid BR (2011-2015 model) is somewhat similar to the original UV (BR). I can say that the view on my Trinovid can be quite immersive also.
I'll have a go at a brief comparison today between the EDG, UV+ and Trin BR and see if I can ramble anything meaningful about their colour rendition.
