I’m coming off the last 2 pair of binos being 8x and jumping back into 10x. Anyone else finding 10x42s to be the sweet spot for a variety of environments?
What 10's did you settle on?
I love wide FOV 8's for still-hunting under 300y, 10's for everything else.
I would agree. But also one who lives and hunts in the West, I also hunt in the South, where I have some deer stands, I can’t see over 75 yards, and always have used my 10X42. However, I can hold my Swaro 12X42 NL Pures steadier than I thought I would, so they are the ones going with me the most now.I have a feeling there were way more 10x binos sold in the last 5 years than all the other options combined.

Thanks for sharing that. Your or someone else posted something similar quite a while ago and makes good sense.I’m a 10x50 guy and not a 10x42 guy. I have lots of reasons for why, so I’ll apologize in advance for my long winded reply.
Handheld binos, for 99% of people, consist of 4 options: 8x42, 10x42, 10x50, and 12x50. Sure some guys back east hunt with 6’s and some he-men swear they can handhold 15’s, but those are almost always the 4 combos compared. What you select all depends on your use case and where you hunt, but for me (high country mule deer and elk), I’ve unquestionably settled on the 10x50’s. Here's my justification:
Exit Pupil (diameter of the column of light that exits the ocular lens and enters your eye).
8x42 - 5.25mm
10x42 - 4.2mm
10x50 - 5mm
12x50 - 4.1667mm
The human eye optimizes around an exit pupil of 5mm. Much smaller and you're leaving light on the table, much more and you're carrying extra bulk that your eye can't use. So 10x42 and 12x50 are out.
12x is too hard to handhold. Lots of guys will say you can, but whenever guys say "buy a 12x50, it's still possible to handhold effectively," the inflection in their voice sounds almost as if they're even trying to convince themselves that what they're saying is true. It's not true across the board obviously, but objectively, lower mag = easier to handhold, especially one hand while bow hunting. I don't want separate binos for rifle vs. bow hunting, so the 10x and 8x win out again. here
So we've already eliminated the 12x50 from contention. Exit pupil is too small, and too hard to handhold. That leaves 8x42, 10x42, and 10x50. The 10x42 is eliminated here because of the small exit pupil (relative to the two other choices).
The magnification is a personal choice thing. The exit pupils between the 8x42 and 10x50 are effectively the same, with just a 0.25mm difference. But the additional 2 magnification of the 10x vs 8x does the same thing that jumping from a 10x to 12x does, but you're not giving up light. Basically, it gives the best tradeoff of FOV, light transmission, hand-hold-ability, and magnification you could hope for in a dedicated western hunting optic.
If I ever hunted back east, I might consider the 8x42. But I live in the rocky mountains and am an unapologetic western hunter, so the 10x50 is my huckleberry. My family and the guys I've hunted with have all jumped on the train as well and have become believers.
This is just my opinion, keep in mind. I'm sure lots of guys will argue an opposing viewpoint, and that's ok. But that's my justification of a 10x50 for dedicated western hunting.
Haha I bet it was me. I’ve copied and pasted my exact same post across multiple threads regarding these types of questions. I’ll never stop proselytizing in favor of the 10x50’s.Thanks for sharing that. Your or someone else posted something similar quite a while ago and makes good sense.
I've had 10x42 and will look at 50s if/when I change.
Also, gives reason to consider 8x when looking at a smaller/compact pair.
