Message: <blockquote data-quote="Kevin Purcell" data-source="post: 1273132" data-attributes="member: 68323">The bigger question perhaps is "Do you know who is making reasonably priced middle and upper quality porro prism bins (with decent eye relief!)". Then we could anonomize it <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" />It seems the lure of margin (and perhaps fashion ... "All the cool kids have roofs") is dismantling the porro market even though the best value (for the consumer) is there.OK, the porros aren't all gone but the distribution is skewed e.g.<a href="http://www.google.com/search?&q=site:www.eagleoptics.com/index.asp+%22porro+prism%22" target="_blank">http://www.google.com/search?&q=site:www.eagleoptics.com/index.asp+"porro+prism"</a>And innovations like porros with internal focusers, like the Leupold Cascades, Vixen Foresta, avoid leakage issues or the "rocking bridge" but none have ED. And I don't see any reviews of them here either.Am I missing one?Does the roof prisms design (despite the drawback in transmission) make other design trade-offs easier (FOV, ER, etc)?</blockquote>
