Message: <blockquote data-quote="Vespobuteo" data-source="post: 3313711" data-attributes="member: 120830">the SF is aprox. 60-70 grams lighter than the SV, it's very noticeable using them, so Swaro have something to work on there,but not everyone prefer lighter weight,and the solid and robust feel of the current SV:s I think is a major selling point.when it comes to carbon fiber, magnesium is already very light,I'm a frequent cyclist and super light bike framesmade by magnesium or carbon fiber,are about the same weight, those high end 2-2.5 pound road bike frames are very expensive,and can cost more than any single Swaro bin does,and not realistic for ordinary people like me.The housing of a binocular is only part of the weight,perhaps 250-300 grams for a 42mm?, it's a lot of other stuff in there to,And don't forget that the FL:s where CF reinforced polymer,and the 42mm:s where not much lighter than the SF.BUT Minox manages to make an 8.5x52 mm bin with a weight of 775 gramsin magnesium. The APO HG 8x43 model weigh only 660 grams.Are they any good? Unfortunately no HD glass in the 52mm version."The second and the last drawback of the Germany manufactured Minox HG 8.5x52 is too high level of chromatic aberration. It can also be, at least partially, an effect of slimming the device down. The shorter the binoculars are, the shorter their focal length is. With a given diameter you have to use fast lenses and these are more difficult to correct when it comes exactly to that aberration."<a href="http://www.allbinos.com/211-binoculars_review-Minox_HG_8.5x52_BR_MIG.html" target="_blank">http://www.allbinos.com/211-binoculars_review-Minox_HG_8.5x52_BR_MIG.html</a><a href="http://www.minox.com/fileadmin/media/Anwenderberichte/MINOX_APO_HG_8x43_translated.pdf" target="_blank">http://www.minox.com/fileadmin/media/Anwenderberichte/MINOX_APO_HG_8x43_translated.pdf</a><a href="http://www.minox.com/index.php?id=hg_technical_data1&L=1" target="_blank">http://www.minox.com/index.php?id=hg_technical_data1&L=1</a>For the 42mm Swaros the weight is not much of a problem,but a lighter future 50mm would definitely make it more interesting for me.optimal bin weight I think is around 800 grams IMO,but since the 50mm is 999 g today, 20% weight reduction with same optical performanceis probably not realistic,</blockquote>
