Kevin and I, and I think Steve, agree on the color bias but I think that is the only area that all three of us share the same viewpoint.The size of the sweet spot in my unit is very generous but not at the level that Steve is reporting. I would rate it slightly better than the 70% that Kevin mentioned but, strangely, my Zen ED actually has about the same level. The Meopta is just a bit better than the Zen ED though the two are really close overall. Guessing at percentages is never accurate but as a frame of reference I would put the sweet spot of the Zen ED at about 75-80% and the Meopta at between 85-90%. Both bins have a very gradual transition from the sweet spot to the outer edge of the image out of focus.I am having a bit of trouble with perceived sharpness. The ZRS look reasonably sharp but I think the red-orange color bias takes away some of the perceived sharpness for me. If I stare at the image long enough then I can see some of the same details that I can in the Legend or the Cascade porro but the details are much easier for me to see from a more relaxed state in either of the latter two bins.Speaking of which, Kevin, your comments on CA surprised me a bit. I haven't really gone looking for it in the ZRS yet but I do pick up on it relatively easily in bins that display noticeable amounts of it. Out of the three I am comparing the Legend is easily the worst (though not "bad" in the grand scheme of things). The Cascade porro displays some but it is much better controlled especially in the center of the field of view. I will give the ZRS a go in that regard tomorrow.</blockquote>
