<strong>Telescope</strong> <strong>Reviews</strong>: <strong>William</strong> <strong>Optics</strong> <strong>7x50</strong> <strong>ED</strong> <strong>binocular</strong> <strong>minireview</strong>Using a RAF chart, the <strong>ED</strong> matched the Nikon 10x42 SE in resolution. Butwhat sets this <strong>binocular</strong> apart from the SE and other non-<strong>ED</strong> bins is itsgreater color saturation.With the Nikon SE, I can see remarkable detail, however, the SE reveals onlya few subtle COLOR variations in a male Cardinal's bird feathers (which otherthan the wings appears solid red at first glance). The 10x50 <strong>ED</strong> shows a widerange of color variation and some subtle colored details not visible with theSE.Yesterday, I spotted two cedar waxwing families, who have taken up winterresidence in my backyard "wildlife habitat" . I watched them for about a halfhour with my 8x32 SE, Swift 8.5X44 Audubon, and 10x50 <strong>ED</strong>. All three binsare very close in resolution, despite their different powers and objectivesizes. The colors looked somewhat "flat" in the first two bins (more contrastwith the SE) whereas the red wing tips and yellow-tipped tail featherspopped out with the <strong>ED</strong> <strong>binocular</strong>s and showed subtle variations in color.Given that COLOR variation is a key field mark identifier for birdwatchers,particularly when trying to discern different species in the same genus, I'msurprised there are so few <strong>ED</strong> <strong>binocular</strong>s made.Cost is obviously NOT the reason since Celestron and Eagle <strong>Optics</strong> pricedtheir <strong>ED</strong> bins between $300 and $400, and now WO has a <strong>ED</strong> bin for under$300.--------------------brocknrollerBows and flows of angel hair and ice cream castles in the air,And feathered birds everywhere, I’ve looked at clouds that way,But now they only block the sky, they rain and snow nearly every night,So many Messiers I would have bagged but clouds got in my way.I’ve looked at bins from both sides now,From up and down, and still somehow,It’s cloud illusions I recall,I really don’t know the night sky at all.(thanks, Joanie)Post Extras:http://www.cloudynights.com/ubbthreads/showflat.php/Cat/0...mber/694293/page/0/view/collapsed/sb/5/o/all/fpart/1/vc/1 (11 of 22)2006/4/26 •• 04:44:56
