雙筒鏡問題
我補多2條links,有關wide angle雙筒鏡:
1. 7x50 Miyauchi Binon vs. Fujinon FMT-SX vs. Tasco No. 124
(大家都係7X50, 一般都FOV只有6度,Fujinon有7.5度,Miyauchi(宮內)有9.5度,Tasco有一隻竟然有11度!)

2. Wide Angle Binoculars:An Overview of Some Classic Models and Challenges for the Future
(原來有好多古董雙筒鏡FOV有9度,其中好多人講的Zeiss Deltar/Deltarem 8x40, Germany 90°, FOV有90/8=11.25度)

我見下面既link提到買10*50比較適合入門人仕
又提及幾個牌子, 如meade, Niscope, celestron等
但係己係幾年前既post
請問呢有無其他新牌子推介?
10x50既話
我問日昇仲有Niscope , $350
巨眼則賣自己的牌子, $280
唔知好唔好用?

Wah! 寫:係呀, dobs似乎好有興趣幫大家找尋值得參考的文章.
但是如果值得參考的文章個個結尾都只係一個/多個"push", 會減低文章的可讀性及價值.
dobs個新post可以加入其他不同類型望遠鏡的連結, 可以"一版通天下"呢!
如果整得好, 我會幫你置頂.
為左提高文章的可讀性, 我會把以下文章的 "push" 回覆清除

There are so many product lines with "Bosma" name. Currently the most expensive one is 猎豹. Apparently it is carbon copy of venerable Nikon SE series, with several major modifications. I've tried 8x32 and 8.5x42 and end up with 8x32. The optical quality is good to very good but still below the original SE or E series.sbod 寫:Push! Push! Push! Push! Push! Push! Push! Push! Push! Push!
江湖傳聞呢期 Bosma 的其中一款雙筒好掂, 唔知其他會係點呢?
Their majar problem is grossly overweighed given their sizes. Alas, they are somewhat pricely.
