此鏡在我未做代理之前已自己買一支作測試。此鏡質數不及其他大牌子望遠鏡。

Kson ED 鏡不是最好的鏡, 但以這價錢能買到此質量, 此是難能可貴.
在色差方面是偏向藍色及紫色, 特別在拍照後會比較容易發覺.
此鏡有一優點是超輕, 約一公斤. 做尋星鏡及導星鏡都合宜.
調焦方面缺乏 10比1 調焦座是一敗筆, 但廠商將會出高級版有10比1 調焦座.
整體而言, Kson ED805.5 是超值望遠鏡.

因著此 Kson ED805.5 望遠鏡, 我決定做 Kson 香港, 澳門, 及台灣代理. 希望能將平價優質望遠鏡引入亞洲市場, 使香港天文得以推廣.
　

I have tested it by myself.

The quality isn't the best, it is similar to MaxXXXXX ED lens. However the price is very nice. (Cheap)
