Allbino's certainly seems to offer up some wild and wooly figures at times, however from the graphs you have shown historically, your's seem to exhibit far more internal consistency .....(ii)  Allbino's has tested all the latest 10x42's, but the 8x's not so much ......  thus it is hard to make comparisons, but the 10x SV certainly is showing an exceptionally high (~94% @430nm) transmission up to 500nm(iii)  I am not sure why the Leica UVHD+ transmits so low in comparison to its competitors, but both yours and Allbino's data shows a tangible (if slight few %) increase in transmission up to about 475nm when compared to the HD model. Therefore, the inclusion of HT prism would definitely seem to be valid, worthwhile and confirmed beyond apology.(iv)  Even though your data is different, Allbino's shows the 10x UVHD+ transmitting more than the mighty HT up to 450nm .....Well that's as much as I want to delve into it, other than to say from the 10x transmission data that Allbino's has presented from its tests (for whatever that is worth), that the UVHD+ is well ahead of the Zeiss SF up to ~475nm .....  :cat:Chosun   :gh:</blockquote>
