I too have joined the legions of Sightron SII Blue Sky 8x32 owners. When Optics Planet ran their $157 inc shipping special a few days ago, I could no longer resist. I've only had them for a couple of days, both overcast, so no thorough testing as yet. However my initial impressions are very positive.
Ergonomics are quite good. Comfortable in my hands, eyecups, while being on the inexpensive side, are also comfortable into my eye sockets and have several settings. I am finding that I can hold it steadier than two other 8X binos in my possession. Eye relief is good, both for use with eyeglasses and naked eye - long enough to accommodate my glasses and yet not too long to where I cannot rest the eyecups against my brow when not using glasses.
My IPD is 74 mm and thus outside of the usable range of many binoculars. But no problems using the Sightron, there isn't much play left, the bridge is open about 1 mm. Right diopter adjustment feels inexpensive, no nice click stops or locks, but it is sufficiently stiff so to hold the setting in use.
While I've read reports of it having a stiff motion in its focusing knob, that is absolutely not the case for mine. Very smooth focuser, with just the right amount of resistance. I wish all of my binos had the feel and motion.
In limited use (hopefully the sun will emerge from the clouds soon), the views have been very good. Sharp images, good color, and reasonably deep DOF. Viewing objects against overcast skies, across snow covered fields and under street lights have yielded crisp, clear images.
Along with the 74mm IPD, I am also cursed with high sensitivity to CA. I've seen CA in every pair of binos I've ever used, and could never use high-index plasic or polycarbonate eyeglasses due to the CA being extremely annoying. When looking at tree branches against a bright, overcast sky, I do see a bit of color fringing (again, I've seen this in every bino I've ever used), but it is well controlled. I pulled out my Nikon Premier LX to compare, the Nikon has less CA, in fact very little. Then I pulled out an old classic, Bausch & Lomb 10x40 Custom. Going back and from between the Sightron and B&L it was very close, but I feel that the Sightron was ever so slightly better.
More testing to go, so far I've been impressed.
