Ok, owning both: how do you characterize the color difference between the 2013 B1 and the current B1 Plus?
No comparison! Remember that I bought mine used in 2013 but the line was introduced in 2005. My sample may very well be from a very early production run.
It displays colours as if its prisms were silver-coated. Not necessarily anything wrong with that, I know very competent birders who use the 1st gen Zeiss Conquest or Dialyt 7x42.
I've stopped trying to spot minuscule differences between my binoculars because I already know they're there and I'm happy with the current ensemble. While my colour vision is very good, it's not fixed to an absolute pitch (which for artists may be equally a blessing and a curse).
I want my scopes and binoculars to be similar and enough neutral that the ability to colour constancy takes care of the 2% difference.
So I'd categorise my devices in three fairly distinct groups:
- Old Meopta 8x32 is more or less alone in its group unless I count the Kowa TS-1 which is much dimmer.
- The big bunch with Nikon ED50A, ED82A, E II 8x30, EDG 7x42, Meostar B1.1 8x32 and Meostar B1 HD 12x50
- Kite Lynx HD and Svbony P406ED 80 mm
First group, as mentioned, is a bit too yellow to be completely satisfactory. Second group, with a minor warmth, which colour constancy sense takes care of immediately. Third group even more neutral, the little Kite still goes well with the Nikon group. Unfortunately the old Meopta and the Svbony scope are the ones I have at work and use together. Not ideal, but manageable.
Within the big group, the EDG stands out as the zestiest one as its contrast appears slightly higher than the rest, closely followed by the E II. This is upon direct comparison, and the differences aren't meaningful to point out.
I'd also like to mention that we not necessarily display the same power of observation from day to day, and from a number of reasons.
A friend of mine, who works with high end audio, has a customer that's more obsessed with sound differences than most other audiophiles (which is quite an accomplishment, btw), and this customer frequently calls my friend believing there's something wrong with his system. Together, they identified a pattern where this dude's ADHD manifests to different degree from day to day. So my friend must remind him of this in a reassuring way and suggest he chooses another activity than listening to music (or rather perceived anomalies in the sound produced by his excellent system). From my own profession, I know this can happen with vision as well.
