The exact text of Tobias' comments:
Flare suppression (8x32)
A really outstanding performance, and even more so considering the small size of this glass. There can be some veiling glare viewing towards a high sun, but generally the image is very clean. It is fascinating to watch in difficult situations, for example towards a low sun, and still have the highest contrast with very black shadows. I could scan very bright backlit water without glare in the view.
So considering the lede is "a really outstanding performance", I would say it's not fair to characterize that as though the little Leica had glare problems, just that he pointed out the one situation where it's not great.
This conversation caused me to grab my wife's 8x32 UVHD and take them out for a walk the other afternoon, and it reaffirmed my impressions that they have similar outstanding glare control to other Leicas (including my 7x42).
In my experience the ONLY time glare is a real glare "problem" with the Ultravids is the situation Tobias describes -- pointing in the same direction of a very bright light source (i.e. setting sun) there are sometimes "veiling crescents" along the edge of the FOV. However (unlike some bins like the M7 8x30) the "crescents" stay at the edges, they don't produce a "milky" wash that obscures the image and reduces contrast.
You can see this by holding the binoculars out away from your face and tilting them so you can see the exit pupil at a distance -- with a bright light source off axis, you can see a crisp bright "rim" at the edge of the exit pupil opposite the light source. But the area around the exit pupil is black and the bright flare is confined to the rim.
My 8x32 and 7x42 behave this way, and so did the 10x42 Trinovid BR (which everyone knows is an Ultravid under the wrapper). Note that he describes a similar effect in his 8x42 review:
Flare suppression (8x42)
There is a bit more peripheral crescent flaring then in the other four. This makes the image a bit nervous looking against the sun. On overcast days and especially in the twilight the image is very quiet. Despite the peripheral flaring the Ultravid manages to keep very low veiling glare levels in the image center under most conditions, yielding beautiful high macrocontrast.
So I think this is an intentional design choice where Leica went for "mitigation" of veiling glare, perhaps it was more efficient to confine it to the edges than to try to kill it completely? But in all other respects they all seem to be virtually glare/flare free, including staring almost DIRECTLY at the sun (the peripheral crescent flares start up as you move the sun farther off the viewing axis).
CharleyBird - you have several Ultravids already, how do you find the glare control of those? Because I don't think the 8x32 will be any worse, I certainly don't find it to be worse than my 7x42 and in fact it might be slightly better. The 7x42 has those huge exit pupils so it's easier to keep the crescent flares out of sight, but leaving aside exit pupil advantage they might show a bit more of those flares vs the 8x32.
So long story short, if you're happy with the flare/glare control of your other Ultravids, I would expect similar performance from the 8x32 (especially compared to your 10x32).
THAT SAID -- you have three Ultravids alread, including the 10x32! That seems to point to getting something different, like the Zeiss 8x25, if only to add some variety and fill another niche that you don't have covered right now.
