    "Quick-draw" NL eyepiece lens covers -- the answer to a prayer

    The Problem: I hate using eyecup (eyepiece) covers (ECC) and never use them with my 2003 ELs. The 8x42 NL tight-fitting ECCs greatly increased that loathing. Rapid viewing of a suddenly-appearing bird is confounded. I hike 3-4 miles daily carrying binos on various trails. With ECCs removed, I...

    More problem-solving magic when using the NL Forehead Rest

    Note: The NLs have worked spectacularly in other 'normal' settings with no need for the following: This next paragraph is only for those who have not read my recent earlier post (referenced below) re: active adjustment of the Forehead Rest (FR) to counter horrid lighting conditions at a...

    Viewing the moon to gauge stability with/without the Forehead Rest when using 8x42 NL's.

    Old news for some, perhaps, but viewing the moon proved a surprisingly revealing way for making the simple comparisons below. Conditions: Last evening, an hour after sunset. Moon phase Waxing Gibbous, 84% illumination. Replicated five times for each of the following: 1. with the Forehead...

    A quirky advantage of using the NL Forehead Rest in horrid light conditions.

    In an earlier thread, Tehri 'opened my eyes' to the advantages of using the Forehead Rest (FR) with the eyepieces set to 0 (fully retracted). Yesterday, I discovered a quirky additional advantage of doing so. Merely by rotating the FR (expanding its length) allows one to rapidly change the...

    Forehead Rest - unsatisfactory range of adjustment for 8x42s

    The eyecup adjustment positions below are in reference to the NL's 6 eyepiece "click" stops, from a fully extended eyecup (position 1) to fully retracted (position 6). With the 8x42 NLs, the Forehead Rest (FR) is confounding. With the eyecups nearly fully extended (position 2) and the FR...

    Tool for installing NL Forehead Rest

    A pre-owned Forehead Rest arrived today. UGH!! To install it, I need the tool for removing the 2 tiny-diameter star-shaped screws. What size "star screwdriver" is needed? Thanks very much.

    A day afield with 8x42 NLs after 20 years using 8x32 EL and EL SVs.

    Quick note: Before purchase, a superb BF member suggested we use FaceTime to ensure my satisfaction in buying his mint NLs -- a truly appreciated and helpful courtesy! After so many years with 8x32 ELs, this was a big change. Coping comfortably with the greater weight for a prolonged period...

    'Flared' vs. 'unflared' BinoBandit for Swaro NL

    There are two BinoBandit shapes, 'flared' and 'unflared.' Has anyone used the 'flared' model for the NL? I naively prefer its appearance and the lack of buckles. 'Flared' BinoBandit'

    % light transmission: a canard?

    Despite the data for the models below, I've seen a statement on BF that the Nikon is dimmer than the Zeiss. If so, then the manufacturer-provided data are misleading or there is more than meets the eye. I'm confused. Model.................. % light transmission Zeiss SLF...

    Vortex Razor HD country of manufacture

    Been searching for a pair of used 8x42 Vortex Razor HDs, but apparently the country of manufacture has varied from Japan, China, and the Phillipines. Is there a guide by year or serial number to determine where Razor HDs were manufactured? Thanks for any advice.

    Aftermarket Lens Covers for 32mm EL SV??

    Have now lost 3 (expensive) SV lens caps. The aftermarket type shown below fits over (around) the armored barrels, unlike the Swaros -- anyone know if these will fit?? Any better aftermarket alternatives? The SV armor (and thus barrel diameter) is slightly narrower than the original EL. Thanks...

    Jumbo Zeiss microfiber lens cleaning cloths

    For years, I've bought the large 12"x16" (30.5 cm x 40.6 cm) Zeiss microfiber cleaning cloths and cut them into sections. I then seal each cut section in a separate, small, clear plastic bag so that I always have a clean cloth (plus a sealed backup) available in my camera bag, my binocular...

    Non-metal binocular strap attachment clips

    Looking at website photos on the Rick Young Outdoors, their harness apparently requires use of metal rings that will dig into my SFL's attacment lugs so I'm looking for clips that are non-metal. Years ago, I bought some wonderful, durable non-metal, "slide-in plastic clips" but can't find them...

    SFL 8x40: impressions after 20 years with Swarovski EL's

    Been using Swarovski 8x32 EL's since 2003 along with, more recently, Swaro 8x32 EL SV's. Both excellent and as durable as an anvil. The SFL's were purchaed to augment, not replace, my beloved EL's. SFL 8x40s: Image: Bright, sharp and clear -- very nice!! FOV: Nearly identical to my 8x32 EL's...

    Lower FOV for 8x32 NL vs 8x42 NL -- why?

    The opposite is true for Zeiss SF and Leica Ultravid HD, for example.

    What does AMD mean

    I feel like a fool, but what does the acronym AMD mean regards binoculars?l I’ve looked up that acronym on Google and gotten an amazing number of meanings

    Nomi Cam's use of 6-axis robotic equipment to test for lens glare

    Instead of qualitative, uncontrolled assessments of camera lens glare (e.g. I see or never see veiling glare), they use sophisticated 6-axis robotic equipment and software to obtain objective, repeatable tests. Oh to have such a machine for objectively comparing veiling glare among binocular...

    Another one bites the dust

    Re: solutions for reducing late afternoon veiling glare when facing westward but not directly towards the sun. I cut off a hat brim, then stapled and taped it to another hat to form an extended 6.2-inch (15.8 cm) brim -- slightly longer than my old back-up pair of 8x32's (see photo). Miserable...

    Veiling glare: a bird club's unanimous verdict on my 8x32 EL FP

    First, I've learned so much from reading this forum -- thank you all. I've read various posts about veiling glare and disagreements over such among some members for the identical model of binocular, and attributed sometimes merely to "differences among individuals." I've had horrible problems...

    Leica Classic ('Retrovid') Trinovid question

    Is there some technical reason why the redesigned Leica Classic ('Retrovids') Trinovids could not nitrogen purged, and thus be waterproof and sealed against fungus. With new prisms and glass, one would think it would be a no-brainer. In 1973, I lived in a hot, humid climate and my beloved...
