... I thought we were comparing 8x40SFL and UV7X's 
I don't own the UV7's but I can compare the UV8x42HD+ and 8x40SFL directly (both at hand):
I love the UV's but the SFL's have for the first time caused me to wonder whether they'll ever be my goto binos again. I find myself reaching for the SFL's almost exclusively. I'd be lying if I said I didn't wish the SFL's were also made in Portugal or the US
But I've owned a lot of MIJ optics (Nikons BITD, Sony more recently) and I have no doubts about Japan's ability to make fine optical devices.
I don't own the UV7's but I can compare the UV8x42HD+ and 8x40SFL directly (both at hand):
- I generally prefer the SFL's for ergos (lighter, faster, grippier and larger focus knob), and I have no issues with its diopter adjustment (has never moved unintentionally, but then again I was ok with the Trinovids which are similar).
- They both have a relaxing view (I wear specs) but the SFL does have more ER and a larger 'eyebox' (eyepc lens dia), w/out being so generous as to induce any finicky blackouts.
- Both seem equally sharp and the SFL is quite neutral in color, while the UV may be a tiny bit warmer. The UV does have perhaps a little more contrast. I've always thought the flat transmission spectrum of the Leicas (high trans well into red end) helps perceived contrast.
- The SFL has a little wider FOV - if I compare side-by-side, I rationally think it's not big deal. But if I actually use them in field I prefer SFL FOV.
- At first the SFL's bothered me a little with their flatter field (I'm very sensitive to rolling ball nausea), but I came to terms with it relatively quickly.
- I find the build on both (armor, caps etc.) to be high-quality. I suppose I may change my mind in a couple of years, but so far no complaints about the SFL's and of course the UV's are typical Leica quality.
