Just reporting back to say that I got hold of the NL Pure 10x32, as I said I would - so that I could compare it with the NL Pure 8x32 which I already had (still within the return period). I treat them with great care, so don't feel too bad trying them at home.
As I say above, I wanted to try the 10x because I although I love the 8x I wondered if the narrower fov would suit me more.
Most of you will already know much of the following, but I'll say it anyway, in case it's of interest. Spent a long time today comparing the two. I live overlooking fields and a hill, with a fair number of features at different distances, plus gulls, geese, crows and a couple of swans today. So not bad as a way to try them out.
Initially when I got the 10x, earlier in the week, I very briefly had a look through them and thought, nope, definitely sticking with the 8x. But today I wasn't so sure, as I was tempted by the 10x magnification. In a way a difficult decision, but long story short, I'm sticking with the 8x, and am very happy with that decision.
Although I had some reservations (see original post) about the wide fov, it is definitely an advantage, I now realise. I can understand why some might prefer a narrower and perhaps less flat fov, and at times the wide fov of the 8x may feel too wide for me. But the pros will greatly outweigh the cons . And while it might be a little bit frustrating not having the 10x magnification, for me there are so many reasons to keep the 8x. The wide fov and flat view provide a really immersive, almost dramatic view at longer distances, if that makes sense. And also great when following birds in flight, or even when not in flight, but at a distance. And easier to find birds, once you're looking through them, compared to the 10x, of course. Also, maybe psychological, but the 8x seem to have a warmer tone, which I like. In fact, it's probably just that they're somewhat brighter. And the depth of field is greater with the 8x. What else? When viewing garden birds, while the fov doesn't appear too different between the two if you study the edges to see what's included in the view, the 8x feel quite different and better for me - again, more immersive. Stunning, tbh. Both pairs are excellent (in my limited experience) but for me the 8x are astonishingly good.
Haven't tried them out yet for woodland birds, but I know they'll be more suitable than the 10x in that environment. I'm sure the 10x will be suitable for some, depending on what they use them for.
I now own three items which I think are marvels of design and build: NL Pure 8x32, a Sony A6400 camera, and several Samsung external T7 SSD drives.
Okay, I know the last two aren't optics, and I apologise. But all three are objects of beauty

and do what they're supposed to do superbly. Btw, I don't really do much bird photography, more landscape.
