I was playing with the 8x32 FL last night, going from infinity down to maybe ten feet, and I can definitely improve the view by narrowing the IPD at distances below ~25 feet. Sharper and brighter when I narrowed it.The Zeiss may be more finicky than others in this regard. I don't know.All the precision measurements are certainly interesting, but perhaps they tell us more about OCD than IPD. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" /></blockquote>
