7th item in the list. "Field of view at 1,000 yds/m" 113m for the 8x20, 90m for the 10x25Thanks, but I can't see it there, just 5.2 degrees for the actual field? I might need more coffee...

Thank you!! Oh and yes, I belatedly remembered the FoV times the magnification as an approximation, but would have liked to see their claimed numbers as it's an odd thing to leave out. The VPs are 60 degrees for 8x and 10x (I wanted the 10x originally but changed to the 8x as easier to hold and very bright). I just like the feel of the wide view, others may just care about where the subject is in the centre (but those are easier to find with the former). Choices for all...Hi Jon (post #20),
The FOV is the field of view that's covered by the objective.
And the AFOV (Apparent FOV) is the FOV multiplied by the magnification.
So for the 10x25: 5.2° x 10 = 52° (and likewise with the 8x20: 6.5° x 8 = 52°).
As I indicated in my previous post, 52° is the nominal AFOV. The actual AFOV may vary from this for a couple of reasons
- but it's close enough as a starting point for rough comparisons.
Some manufacturers use a more complex ISO standard calculation, as shown here: Nikon | Sport Optics | Field of view
And the type and degree of geometric distortion can also influence the AFOV.
Where a manufacturer lists the FOV in degrees, they also typically list the AFOV in degrees
- I should have paid more attention to Leica only mentioning the former!

Now that I think of it, it’s better to be bitten by the "pocket bin" Cobra than by a real Cobra😁and also pocket binoculars take less space.Yes. I have a number of other pocket bins as well. I got bit bad by the "pocket bin" Cobra a few years back. Good news is IMO there are reasonably useful and enjoyable pockets in the lower and mid price range.

Yes it’s great. Can’t believe the view that comes out of such a small packageI prefer to not drag around a full-sized bin anymore and have it hang around my neck. I became a pocket bin believer when I looked thru the CL 8x25 Compact. The glass is sharp and the price is very reasonable. I plan to get the Curio next spring. Looking forward to an even more compact size and wider FOV compared the the CL 8x25 Compact. I have read several reviews on the Curio 7x21 and all seem very favourable including yours.
I don't wear glasses and they're pretty effortless to use. The twist-up eyecups are just one of my favorite features, along with the ease of eye alignment.I had an issue with the Zeiss Victory Pocket 8x25 since I don't wear glasses and the eyecups don't extend far enough. Is this something that is better solved with the Curio for non glasses folks?
I had that problem with the zeiss too but I added some eyecup extensions and they were suddenly unbelievable (Amazon.com : Acxico 2 pcs Rubber Eye Cover Guards Binocular Microscope Eyepiece Eye Cups for 32-35mm : Electronics). My dad fell in love with them and I let him have them, giving me a chance to try the curio. The curio are much better in terms of eye relief, but for me, they are still floaters. I can touch them to my brow but can't comfortably sink into them like I do my 8x32 EL or the zeiss vp 8x25 with add-on eyecups. I like the curio a lot, but, I have thought about offering it up as a trade for a Zeiss. The ergonomics of the zeiss are much better for my hands.I had an issue with the Zeiss Victory Pocket 8x25 since I don't wear glasses and the eyecups don't extend far enough.

I make it 105mm x 64mm x 45mmCan someone provide LxWxH measurements of the Curio closed with the original rain guard and the eyecups extended? No strap. I am assuming the rain guard will make them larger in all three measurements.
Yes. I just bought a pair of the 7x21 Curios a few days ago. I was looking at other binoculars to compare with my 7x35 Retrovids. The shop proprietor handed me the Curios on a whim, I humored him as I basically gave up on pocket binos years ago, so took a look. Wow, shockingly good, useful binoculars that happen to fit in a pocket.I had an issue with the Zeiss Victory Pocket 8x25 since I don't wear glasses and the eyecups don't extend far enough.

Shockingly good is a very apt descriptor for them and I'm sure they'll continue to make a lot more converts in the future!Yes. I just bought a pair of the 7x21 Curios a few days ago.

As to using them without glasses, they work perfect for me without glasses. I have fairly deep set eyes and they are very comfortable, no blackouts.
I also (as per user "Trinovid") have no issue with the Zeiss 8x25s without glasses, so suggest people thinking of them try a pair, they might be fine like me or have issues like you, they're great binos, so worth doing the test IMHO...I had an issue with the Zeiss Victory Pocket 8x25 since I don't wear glasses and the eyecups don't extend far enough.

Indeed. And if you really need this format (and VP's good FOV) despite having a problem, you may find a workaround. I was able to stabilize it by keeping the top of the eyecup against my brow; whether this slight (but continual) extra effort seems worthwhile would be a matter of individual taste. For me, no.I also (as per user "Trinovid") have no issue with the Zeiss 8x25s without glasses, so suggest people thinking of them try a pair, they might be fine like me or have issues like you, they're great binos, so worth doing the test IMHO...
