Questions about current compact Leica 8x20 BCA models:
I have seen several informal reviews praising the superior brightness and clarity of the Ultravid 8x20 BCA over the Trinovid 8x20 BCA models. This is a question about which 'Trinovid' version, older or current, has been involved in these comparisons and about how different optics of the current Trinovid BCAs really are from the Ultravids.
The older and current Trinovid BCA versions have quite different cosmetic appearances, as shown in the photos below (screen captures from eBay ads). The older version had a series of 'bars' on the surface, similar to those on the larger Trinovid BA/BN models of roughly the same era.
Specifications for the current Trinovid and Ultravid 8x20 BCA models on the Leica site <https://en.leica-camera.com/SPORT-O...a-Compact-Binoculars/Leica-Compact-Binoculars> indicate that important aspects of the optical trains are identical:
"Prism system: roof prism with phasecorrecting coating P40 and HighLux-System HLS®"
"Coating: HDC® multicoating and AquaDura® coating on outer lenses"
The only differences listed are essentially mechanical ones - eye relief (small 1mm difference), closer near focus for the Ultravid (6 ft.) vs the Trinovid (9.8 ft.), and waterproof up to 5m for the Ultravid vs. 'splash-proof' for the Trinovid.
The focusing train is quite different for the two, with an 'extended,' nose-like external control on the Ultravid vs. a control more integrated with the bridge on the Trinovid,. This might be the primary difference, providing the closer near focusing range and the better, waterproof sealing of the Ultravid BCAs.
The questions thus are:
1. Might many of the user comparisons have involved the older Trinovid BCA models? Can any here provide comparisons between the current 8x20 BCA Trinovids and the Ultravids.
2. Is it possible that the optical components of the current Trinovd and Ultravid BCAs are essentially identical, e.g., with both benefitting from phase-coated prisms and newer lens coatings?
3. For those who do not need the closer near focus or waterproofing, can actual optical differences justify the large price difference -- $300, around 67%, more for the Ultravid 8x20 BCAs?
My thanks in advance to any who can offer input on these questions.
