The “raw optical quality” is basically the same, the differences are more about personal taste. More depth of field vs wider apparent FOV is the only significant difference outside of those related to the exit pupil / aperture.Hi Don & eitanaltman
What can you tell us/me about the differences between the 8x32 and the 7x42 UV HD's ?
How do they compliment each other?
What application is there for the 7x42 that the 8 doesn't fill? Other than a few minutes of viewing time late afternoon or early morning ?
Is one more pleasurable to use because of larger oculars and bigger eyeball?
For me, it’s all about viewing comfort / ease of use.
The 8x32 is wonderful but I find the eye positioning a bit finicky, even for an 8x32. I don’t wear glasses and I find the eyecups a bit too small, not just the diameter but they also don’t extend far enough for the eye relief (this will probably surprise eyeglass wearers who have ruled out the 8x32 due to the short eye relief haha); if I just plop them in my eye sockets I get blackouts. So I have to do the little jig where I try to find the perfect spot under my brow to tuck them in so they are positioned a bit further from the eyeball. With extended field use it begins to get fatiguing, especially when my eyes are tired (early morning).
The 7x42 on the other hand is easy peasy. I can still induce blackouts more easily than some other more modern alphas — the EDG 8x42 that I also own currently for example is far more forgiving in terms of eye position. But the enormous exit pupil and generous eye relief means there’s plenty of margin for error. I also find the eyecups of the 42mm Ultravids to be the best, exactly the proper shape, thickness, texture and feel for my preferences. I just slap them up to my face and I nearly always get a perfect view. Combined with the huge DOF it feels like I can be on the bird and in focus faster with the 7x42 than almost any other binocular.
Switching from the 8x32 (or, honestly, most smaller exit pupil binoculars) to the 7x42 to me feels like my eyeballs just got home and kicked off those dress shoes after a long day at work and put on the soft warm fuzzy slippers. I never, ever get eye fatigue with the 7x42. I also find the 7x42 to be utterly impervious to different lighting conditions, more than any other binocular I’ve owned the view is equally good in any situation. Murky post-sunset gloom, heavy overcast with harsh diffused glare, blinding mid-day sun on a cloudless day, doesn’t matter. The view is always great. I don’t even have to think about it, they just deliver with no fuss.
In total, the difference in ease and consistency of the view is hard to describe but (for me) it’s far more significant than the theoretical “a few minutes at dawn and dusk” that people mention when discussing exit pupil. I feel the difference in many lighting / viewing situations — especially overcast / gloom / haze.
Unfortunately it’s something that only gets REALLY noticeable when actually using them in the field. If you do the A/B side by side quick comparison in normal daylight it’s not so obvious. Again the more comfortable shoe analogy — might not feel like a big difference trying them on for a few minutes in the store, but go walk 4-5 miles and it’s glaringly obvious.
Subjectively, I also prefer the ergonomics of the 7x42 for extended field use. The 8x32 is just a touch too small, so I’m not totally sure where to put all my fingers. Not a huge thing but it’s one of the little things (like the slightly fussy eye placement) which adds up when you’re using them in field for hours on end. The 7x42 (for me) is no fuss, I can grab it any number of ways and it works. The compact size, light weight, and the smooth taper of the barrels makes them feel smaller in the hand, more like a meaty 8x32 (eg Zeiss Conquest HD) than a 42mm in terms of handling.
Finally, also on the subjective side of things, I have become addicted to the enormous DOF of the 7x42 and how it feels like everything is clear and in focus. It’s just such a pleasing and relaxing view overall, just some magical alchemy the 7x42 UV has that makes the package greater than the sum of the parts. I never ever miss the incremental magnification difference compared to an 8x. The only advantage of the 8x32 (for me) is the size/weight reduction, I prefer the 7x42 in all other respects.
Apologies if I just complicated things lol
