请看TODD GROSS 在http://www.weatherman.com/ 上对他们做的OEM的15X70镜子的好评. 我想这款20X80也不会差.
25. 15x70 Oberwerk (tested 3)

NOTES: I'm a bit stunned, these binoculars which I obtained from http://www.bigbinoculars.com are very low cost and similar to the Orion 15x70 Little Giants with two exceptions. Firstly, the focus range is short, but heavily weighted towards long-distance.. in fact it even focused without my glasses (-4.25 diopter, just made it). They are therefore good for astronomy, but not necessarily birdwatching. Secondly, they have more eye relief than the Orion 15x70s, excellent, long eye relief, reminiscent of the Orion 10x50 Ultras. The view and feel of the binoculars otherwise is similar to the Orion 15x70s, and the Orion 10x50 Ultraviews, they seem to be Chinese made. They must made at the same factory. Jupiter was a disk and I could barely make out Saturn's rings. I could barely resolve the Trapezium. The moon was crisp and detailed with false color out of focus, but not in focus. The binoculars are very lightweight for their large size, and could be marginally hand holdable for long periods of time. Go to the Orion 15x70 review for more detail on the typical views. |
