係紅狼見到枝鏡既介紹

佢話 :
Let us first explain what is "first focal". As the magnification is increased, the apparent size of the target is increased, but the reticle appears to remain the same size; with the result being that the reticle covers less of the target when the magnification is increased
如果真係咁, 枝鏡就絕對唔係 FFP. 我有枝真品 Schmidt & Bender PMII 5-25x56 FFP 鏡. 個十字係按比例跟著個影像放大. 因為如果唔係咁, 就唔可以打遠距離目標時用十字線上面D刻度作為判斷瞄高幾多既參考.
