    Swarovski NL vs Zeiss SF: a personal comparison of two 8x32s.

    Hi tenex, Remember this thread? https://www.birdforum.net/threads/holgers-new-review-the-nl-8x32-vs-the-el-8x32.411147/ Looks like you were one of the participants. Deja vu all over again, isn't it? This thread started as a review of the 8x32. I haven't seen the 10x32, but I expect the fronts...

    Swarovski NL vs Zeiss SF: a personal comparison of two 8x32s.

    To anybody following this thread who now imagines that the NLs are "glare monsters" I would suggest re-reading Canip's post above. Even though I've criticized my 8x42 NL for its lack of completely effective baffling I still use it everyday without much complaint. There's a big difference...

    Swarovski NL vs Zeiss SF: a personal comparison of two 8x32s.

    Tom, I hadn't planned to say anything more on this subject, but I just noticed these bits from you post #88 which appear to be directed to me. Frankly, I thought the photos where self explanatory and answered your questions. If not, I'll try again. First, notice that the exit pupil in the...

    Swarovski NL vs Zeiss SF: a personal comparison of two 8x32s.

    None of these three is subjective or personal. Rolling ball is what happens when objects near the field edge have their shapes distorted by angular magnification distortion and are set in motion by panning the binocular. Whether individuals are disturbed by the effect is what is personal, not...

    Swarovski NL vs Zeiss SF: a personal comparison of two 8x32s.

    You've already seen it. The bright crescent of internal reflection at the bottom of the photos I posted earlier in this thread is the glare brought to a sharp focus (link in post # 21). When you look through the binocular in the usual way the the same crescent of light becomes unfocused and...

    Swarovski NL vs Zeiss SF: a personal comparison of two 8x32s.

    Glare is created in all binoculars when an off-axis light source, not necessarily as bright as the sun, but much brighter than the scene being observed excites an internal reflection at an angle that sends bright non image forming light into the eye. The point of baffling is to block that light...

    Swarovski NL vs Zeiss SF: a personal comparison of two 8x32s.

    I hope not. I think that day for Dennis is only a few months away. It's the day, after months of not noticing any glare in his 8x30 Habicht, he looked up some cliffs at mountain goats backlit by the sun and saw the light. Off to eBay they went. I'll continue to enjoy my NLs too, long after the...

    Swarovski NL vs Zeiss SF: a personal comparison of two 8x32s.

    Everyone can see the glare in the 42 and 32 NLs, even you Dennis, provided the lighting situation is right, your eye's pupils are centered on the exit pupil or are rotated in the direction of the glare. And everyone can fail to see it if the lighting situation doesn't stimulate the reflection...

    Swarovski NL vs Zeiss SF: a personal comparison of two 8x32s.

    The glare source in the NL is at the objective cell in the front of binocular, not the eyecup (see the link to photos in post #19). Completely sealing the back with winged eyecups doesn't change it at all.

    Swarovski NL vs Zeiss SF: a personal comparison of two 8x32s.

    Hi John, Believe me, I'm the least enthusiastic defender of the Field Pro system, but it has allowed me to put my harness on any old way and then just crank the relevant lug to take out the twists, a minor advantage. Henry

    Swarovski NL vs Zeiss SF: a personal comparison of two 8x32s.

    Hi Lee, Here are some photos that show how de-centered pupil positions can either eliminate or exacerbate the source of glare in the NLs. These show the 8x42, but the 8x32 I examined had similar glare coming from the same place...

    Swarovski NL vs Zeiss SF: a personal comparison of two 8x32s.

    Excellent comparison, Lee. I think all your criticisms of the 8x32 are valid and apply equally to the 8x42, except for glare resistance. I've found that the 8x42's glare can be reduced to near extinction with careful initial adjustment the eyecup length and the IPD settings. The small exit...
