Meanwhile, getting back to the subject of narrow IPDs, mine is 58mm which is quite narrow, but easily accomodated by my SF 8x32s that have a published IPD range of 54 - 76 mm, and also by the SFL 10x40s that I am reviewing which have an IPD range of 52 - 74, and although my trusty Leica Trinovid HD 8x32s have a published IPD range of 58 - 76 they will actually close-up a bit narrower than my IPD.
