Yes, I am mistaken, straight through prisms would set the center separation at the IPD regardless of the objective size. I'm not sure what it is that causes the better 3-D effect in full sized roofs than compact or midsized roofs, but it's very noticeably, for me, at least. [smilie scratching head would go here if there was one]The image in compact and midsized roofs looks more "compressed" than full sized roofs. They give the impression of less DOF and less 3-D effect. Objects don't "stand out" from the background. When looking a tree lines that are one in back of the other, they seem to be closer together than what I perceive naked eye. Consequently, I can't get comfortable with the view in small roofs, because it looks unnatural. OTOH, I found the 8x42 HG's view more natural and porro-like than the 8x32 HG. That is, the impression of DOF and 3-D effect were much stronger. In fact, if not for the "rolling ball" in the full sized models, the 8x42 HG would have been my roof of choice. It generally follows that the higher the magnification, the more compressed the image looks, as I think you pointed out above. Which still makes me wonder how you can expect objects to "stand out" in a 10x roof like in your lower power bins?  It seems like what we have here [spit] is failure to communicate. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />I'm not sure what the difference is btwn what I'm calling "3-D effect" and you're calling "stand out". To me, they are the same. The best 3-D effect/stand out effect I've seen in binoculars was in the Fuji 6x30 FMTR-SX. It was like looking through one of those old stereoscopic slide Viewmasters. Foreground, mid-point, and background were all very clearly delineated, with very little image compression. Objects "POPPED" out at me in a way that was beyond real, almost "surreal". Like "op art". If not for the IF EPs, it would be my midsized bin of choice. Like my old friend Roseanne Roseannadanna used to say, "If it's not one thing, it's another!"Optics are always a compromise. Getting it all in one bin is a herculean task. Brock</blockquote>
