    Help with interpreting Opticron tech data, please?

    Can't vouch for the accuracy of this, but the Opticron naming might be decodable after all! https://www.birdforum.net/threads/opticron-ed-hd-vhd-glass-and-coatings-very-confused.446191/post-4533687

    Help with interpreting Opticron tech data, please?

    Oasis is a name they use for anti- reflective glass coatings. I do not believe they are dielectric coatings, needed for reflections in SP prisms ( not like porro or AK with total internal reflection). I have the Verano....it is the next level above the Traveller, so I would expect it to have...

    Recommendations for mid-level (US$400-600) 8x42s?

    E2s are reported to be very good mid level bins, they are on my list for a few years ..... However, today they cost £700 ( latest better coatings), a massive increase from when they were classed as good value.

    New binoculars under 200€

    They have good multi coatings, phase coated and have dielectric reflective coating on their prisms. This has enabled them to outperform aluminium or sliver reflective coatings on other entry level bins. They are noticeably brighter than some of the other bins ( from memory..... I'm actually...

    New binoculars under 200€

    Please note that my list contains bins from ~£100 to ~£400..... So in general terms the sv202 does not better all of these IMHO. Regarding weight.... Sorry I have not checked actual numbers. Because the P7 is entry level and reported as predominantly plastic (comparable to the Nature DX, Sierra...

    New binoculars under 200€

    The sv202s are magnesium alloy and are heavy and robust. If weight matters, then a light weight plastic bin like the yf II porro or P7 would then be better in the OP list. Edit... The Opticron Savanna Porro is identical to the yf II and they are good entry level porros, if that is desirable.

    New binoculars under 200€

    This will be a repeat of the same debate. You won't get a balanced answer. I suggest you look at what jarrelli has written..... He is reliable, has used many bins and has an open and balanced outlook, with no axe to grind...

    Aliexpress monocular

    Yes, this is what I posted a few weeks ago too. I too thought it was okay for the price. Also, it small and light, perfect for the purpose I bought it for .... Lightweight hiking in the mountains.

    Brief review of Meopta Meostar B1+ 8x42. (in comparison with Zeiss Victory SFL 8x40

    Perhaps another game changer

    My understanding, which might be wrong, is that they deliver the APM porros too, so your assertion is possibly correct. They do astro kit too eg superzoom (sold under an APM label too).

    Perhaps another game changer

    Perhaps a better description of these could be " a roof bin to rival NLs' :...... That way, the emotive debate about 'copying' someone else's "design " is removed completely. An SP roof bin is an SP roof bin ......

    Perhaps another game changer

    First reports coming in of an 'NL' clone ..... https://www.cloudynights.com/topic/908681-new-bino-developed-by-skyrover/ Looks like Sky Rover have produced a new range of roofs, to go with their extensive range of excellent astro gear and bins. Definitely one to watch.

    Zeiss and Swarovski 10x32 flat field question

    When I was considering and researching the SF, I found that the across field resolution test results showed that it was not sharp (flat) right to the edge as one would have hoped for in a premier level bin with field flatteners...

    Brief reviews about Zeiss victory SFL 8/10 x40

    Is the SF 8x42 edge performance notably better than the SF10x42? According to the resolution measurements across the field of the 10x42, these didn't look particularly good: https://www.birdforum.net/threads/encounters-with-zeiss-8x42-ht-and-sf.313034/post-3300908

    Looking to decide on a new binocular

    IMO I would choose the GPO HDs. Read the reviews yourself, the well grounded reviewers are suggesting they are playing in the top class league, not big brand name mid range, despite the price equivalence to the others ....I am considering these myself as I am happy with my GPO Passion 8x56.
