P.S. I'm still a big fan for the Sightron 8x32 and enjoy using it. I love the ergonomics and the on-axis sharpness, it is simply very easy to look through. My only major criticism is that it has an odd glare issue issue when there is something very bright several fields of view outside the image at a particular angle. I have only rarely noticed this in very brightly backlit conditions during the day, where the image gets a bit washed out. I was able to diagnose it at night because there was a streetlamp in just the wrong place one night while looking out over a dark ocean at star clusters.
Quite agree that Sightron images get washed out in that way. I guess that it is a fairly common issue, perhaps related to the clarity which
Chosun Juan has explained. However at the moment I have nothing to compare directly with Sightron.....
Chris, that's not entirely a correct understanding of what I was saying. 'Clarity' and 'Glare performance' are two separate things.
'Clarity' is that quality of the view that seems 'transparent' and is usually associated with Porro or other 100% internal reflection prisms such as A-K etc. S-P prisms (the best with dielectric coatings giving ~98 - ~99% transmission) lose enough of the spectra at various wavelengths to ever so slightly compromise 'clarity'. Even something with such a well put together view as a Swarovski SV loses just a fraction in the 'clarity' stakes compared to a Porro, A-K etc. The best S-P prism bin that I have seen in terms of getting close to 'clarity' would be the Zeiss SF - though it has other issues such as slightly skewed colour cast to my eyes which prevent it having complete 'clarity', along with ever so slightly perceptible dielectric coatings losses.
It is entirely possible for a bin with great 'clarity' such as my former Swift Audubon 8.5x44 ED to have woeful 'veiling glare' performance ! Have the sun in the right spot and Wow! Have it in the wrong spot (anywhere within ~30° of the sun [which is pretty poor]) and uggh! almost complete washout - you might as well be looking through your hat for all you can see .....
I haven't followed this Sightron thread at all, so I'm not up on its glare performance. From what I gather it has very nice sharpness (which is one of the requirements of 'clarity' - but nowhere near the only one and not enough to make the grade on its own), but also a readily perceptible yellowish or warmish colour cast (which ruins any small sense of 'clarity'). If the Sightron has veiling glare issues, then of course that will ruin any nice view that it has.
One of the ways I assess glare performance is to just make a simple right angle with your arms (one pointed at a low sun) and then just simply halving the angle and noting glare performance as you go. It's pretty easy to identify large fractions - angles of 45°, 22.5°, 30° etc. Note when you start seeing 'crescent glare', and when 'veiling glare' starts, or completely washes out the view. Either that or carry a protractor with you.
I WOULD BE VERY CAREFUL AT ANGLES TO THE SUN OF CLOSER THAN 22.5° - I 'd suggest that if your bin has no glare issues by 15° that you give the exercise away as that it Outstanding and well and truly good enough. It's a very good characteristic (ultimate value, and the progression) of your bin to know - that way, in the heat of the moment following a rare sighting, you will already have programmed into your brain early warning signs of an impending harmful full sun view - and can avert in time. KEEP SAFE. :t:
Hope that helps 'clarify' things.
