I have spent a lot of time behind mine bear and elk hunting and never noticed any kidney beaning. I don’t wear eye glasses, so maybe it would be an issue if you did.
I think one issue is the inability to put an outdoorsman's stud on the Kowa Genesis vs. basically every other binocular.
Now I need to go and look at mine. I assumed they were the same as my 10.5x44sThe 8x33 Genesis does have a tripod exit unlike the other models.
That’s good to know.I have spent a lot of time behind mine bear and elk hunting and never noticed any kidney beaning. I don’t wear eye glasses, so maybe it would be an issue if you did.
Just received an SFL 8x30 and eye-placement is critical, to say the least? I like everything else but the eye placement issues are taking some getting used to?"Kidney beaning" is simply an eye relief/placement issue. The Conquest HD is well known for it's terrible eyecup design which is why Zeiss will (at least they used to) send you a free pair of extended eyecups if you asked. IME this blackout "problem" is most prevalent in 8x32 class binos.

Plus ego.Marketing.
Weight.
Ergonomics.
FOV.
There's more to it than merely exit pupil. Eyecups and ability to achieve proper alignment contribute, as JGR posted earlier.Isn't...
objective diameter / magnification
... a rough indicator of how forgiving a given optic will be with eye placement? Exit pupil?
It's why 6x should be normalized on ultra-compact binos.
And why 8x44 and 8x50 are extra forgiving.
Been a few days now and I’ve spent a bit more time behind the 8x30 SFL-the eye placement problems have almost disappeared and I am quite happy with the ergos, the lack of mass(wow!) and the clarity of the optics. Looking forward to using these in the field when weight is an issue.Just received an SFL 8x30 and eye-placement is critical, to say the least?

I understand completely and feel the same way about my 8x42 SLC's. My new Razor UHD 8x32 is on the verge of replacing the SLC for the same reasons you mentioned. It is outstanding.Back to Kowas...
The 8x33 that I had did not seem very exceptional in use. However, every time I compared it side by side with my 8x42 SLC W B, I was really impressed. Other than the blackouts.
In low light the 33mm was right there with the 42mm, with my middle aged eyes. Even in timber with fading light. Only when it was near complete darkness was there a noticeable difference, which could matter to some people.
Regarding resolution, the 33mm was really good for seeing fine detail but the 42mm SLC was sometimes better. There were times when I could not identify something with the Kowa, but could with the SLC. I have better than 20/20 vision, corrected.
Some of the "wow" and ability to see fine detail with the W B might have been the contrast or color cast. The SLC image was stunning to my eyes, but the glare drove me crazy. That is another eye placement issue, to a certain extent.
Believe it or not, the 8x32 CHD has replaced my 8x42 SLC. I like the smaller overall size, and really enjoy the view. I may have gotten a really good sample but I compared it to several 30-42mm binocs including NL. The only ones with better resolution were the 8x42 NL and 8x40 SFL. The 32mm and 42mm NL had the worst glare of anything that I tried. Zeiss overall were excellent for glare. The 8x42 CHD having the least of any I looked through.
I too prefer looking through my 8x32 Razor UHDs than my Kowa Genesis 8x33s I recently purchased however I dislike the excessively slow 3 1/2 revolutions on the UHD's focus knob which feels rather heavy compared to my Razor HD and hopefully it loosens up with some use.Because when using high end glass, the "best" is always subjective. For instance, I found the 8x32 UHD superior to the Genesis 8x33, and IMO the NL's stand alone as the best hunting binocular known to mankind. Ergonomics play a big factor as well. That's why I always say you've got to try 'em for yourself, as your eyeballs may see things differently than mine, and vice-versa.

I used the Kowa 8x33 for grouse hunting in the snow for a season. The lack of CA was impressive!I do appreciate their sheer lack of CA (I personally really hate CA when glassing and avoid buying optics with well known CA) and like the smooth bare metal textured focus knob which focus rather quickly kind of like a Maven but not as noisy.
This is exactly one of the reasons I'm so impressed with the UHD, the slow focus is much easier/quicker to get sharp image that a fast focus bino like the Conquest HD, where you're constantly overshooting the sweet spot for sharp focusing. Super fast focus is more for the birdwatching crowd IMO. I also find the focus tension perfect, and uber-smooth.Sometimes slow focuser is a good thing, for hunting binocs. Maybe less so for birding or action sports.
I don't mind some resistance in the focuser, as it keeps it from inadvertently moving when going in and out of a chest purse.
