Everything you say is correct, but I doubt you are prepared to claim that those factors alone explain a $2,000 price difference.Having worked for varying manufacturers there is is often an extra charged made for very strong brands. You may be able to sell them for
more based on a very similar specification product if you can get them to appreciate the brand value.
With heritage brands this can add more due to the ‘story’ that you can buy into. You aren’t just buying the product but the ‘history and lifestyle’ that it represents.
There are the extra costs, R&D, Warranty, Spares, higher production costs etc. What seems more of a concern is there seems to be a restricted ‘free market’ on some brands to be a ‘dealer’ (but that’s probably another story) so you don’t see much direct competition?!
You also do see some Chinese and Japanese binoculars that are the same but released under different brands and they charge more if there is a perceived value associated with their brand.
Spend more, and you get a better instrument, no matter how many rail against that simple and fundamental fact.
Anyone who says “A Swarovski NL is not worth $2,000 more than a Whatever” is neither stating an objective fact or an attribute of the NL. They are stating an opinion, and those are like that other thing that everyone has one of.
