And I fully understand we're all different in terms of hand size, preferred grip etc.
I'm right handed.
With every binocular I've had / have, I prefer to bring it to my eye with my left hand as my right flicks off the eyepiece cover. Thereafter I traditionally use my left as the primary 'gripping' hand and my right as support / anchor for my right, index focusing finger
I did try your way with my left hand - but that required me to focus with my left index. This didn't work for me - it felt truly odd.
When I tried your way with my right hand, it then felt really odd bringing the binocular to my eye with that hand, plus I was consistently all-of-a-fumble with my left.
This might all be pretty academic if one is just lazily enjoying landscapes etc, but when fractions of a second count in getting a bin from chest to fully focused then having to think and awkwardly fumble just doesn't work for me.
It might just be me, but that was my experience.
I am sure we all have different ways of holding binos in the complete belief our way is the most natural way! Full disclosure: a lot of the time I hold the bino with my right hand as described and focus with the first finger and often my left hand simply supports the weight of the binos on the tips of the fingers with my left-hand thumb pointing backwards to rest on my face the give extra stability. Pretty sure that is not recommended by any birding organisation but it works for me. In strong winds though, I have to use my left hand to grip in a similar way to my right hand.

Yes, a lovely getaway and account of it. Around here we have to content ourselves with muskrats.
(1) when SFLs came out, several people reported that they simply didn't like or weren't as impressed by the 10x as by the 8. I don't know why myself and am not going to spend time trying to locate them again, so I hope they show up here to explain themselves. (I presume they didn't simply prefer 8x to 10, as there would then have been little reason to try the 10 at all and none to say this.)
(2) several people (including me) thought both SFLs had too much contrast especially around edges, leading to a busy or even distracting view in some situations. I didn't allude to this above but do now in order to lead into...
(3) in a brief trial, I found focusing odd with the 10x, looking for example at a leafy tree in the short to middle distance, that I wasn't quite sure where or when it was focused because nothing seemed clearly out of focus as it would in my own bins, presumably due to some combination of #2 above and possibly also busy (multiple-edged) rather than smooth bokeh. (I don't think anyone else mentioned this. Perhaps it would have helped to have a yellow bird in the tree.)
I gather from your response that you didn't experience any of this, that you like the visual presentation of both SFLs equally, found focusing with the 10x40 perfectly straightforward, and no other difference in use between the 8 and 10x than the usual ones?
(I actually expect this to be a rather short thread now, as SFLs have been available long enough for everyone to try them, most issues were hashed out already in the 8x thread, and this forum is full of 7/8x'ers anyway.)
This is exactly what I recall myself in either SFL, and quite like many/most other bins (BN, E II etc).
"Those folks" is just me... I see that these issues haven't lodged in everyone's mind as they seem to have in mine, and I should have reviewed them more carefully:

Absolutely correct and while I didn't have another 10x bino here I did have two 8x32s that I have listed elsewhere and swapped between them and the SFL without noticing anything bothersome about the view, or the focusing of it, through the SFL.
I might be jumping to conclusions but I think I see the difference in how we are both using these binos. You said "Perhaps it would have helped to have a yellow bird in the tree". I am using these binos to look at subjects that grab my attention, as I hope you can tell from reading my review. Your description of looking at a tree with no bird in it suggests you are just looking at an available scene and then trying to analyse how the bino has represented it. I humbly suggest it would be better to wait until any kind of bird lands in that tree (or anywhere else) and then focus on the bird. I think having a genuine central subject of interest would enable a better assessment of the bino's view. For example focusing on this subject of interest and de-focusing back and forth a little would emphasise the extent of the depth of field i.e. the volume that is actually in focus, and therefore, the rest of the scene which is out of focus.
If you have a continuing difficulty in seeing what is in focus and what is not, it suggests to me that you need to re-set the bino's dioptre adjustment and/or visit an optician to have your vision tested.
BTW some members might be wondering why I haven't got my all-time favourite bino (SF 8x32) here. The answer is that I knew that if I brought it I would be tempted to use it and not spend as much time looking through the SFL as I should to write a proper review, so I put temptation behind me by leaving the SF at home.

In the midst of some of the raging controversies on here, one cannot help but wonder just how well some posters can see.
The observer’s visual acuity would seem to be a rather large part of the equation, especially in cases where instruments of widely different prices are pronounced as the same, or virtually the same. (optically)
It becomes annoying when those who do see a difference are derided as “fanboys” or deemed biased toward a particular manufacturer by those who do not. (see a difference)

Thanks for the review. Good to see some support for the 10x40.
I have a pair. I wanted to try them out against my 10x32 SF. As I've stated elsewhere, I think the SFs are really exceptional, other than occasional blackouts being a bit annoying.
I didn't get a chance to compare them head-to-head, as the SFLs arrived just before I moved to East Africa, and I'd already packed up the SFs to go in our shipping container. My general impression of the SFLs was that that they are very good, but wouldn't take the place of the SFs in my affections, so I decided I'd sell them. The container is arriving at the end of next week, though, so perhaps I'll finally do that head-to-head comparison.
I now want to try out the SFL 8x30, when they appear. As I already have the Curio 7x21 and VP 8x25, I think they might replace the 8x25s, and be a perfect companion to a lightweight scope.

Do you think we were all born yesterday? You've clearly never even been to Scotland - most of your pictures show sunshine.
Growing up, I was always told too much fiddling would cause a permanent blackout. (Titter, titter. Oooh, matron!)
Never had any problems with the 8x32 SF, though. And I don't find the 10x32 much of a problem in actual use (as opposed to just scanning around to look at the optics). Typically, these issues get better with time as you become more accustomed to the bins.

That's why Lee spent 3 weeks there, for that special sunny day.
Probably also took a fast lens.
