Rwa first focal scout scope

FFP 對玩具槍其實係冇用.  zoom 咗後條十字線會變肥, 有視線被阻著既感覺.

係紅狼見到枝鏡既介紹http://www.redwolfairsoft.com/re ... ut_Scope_1_6x24.htm

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.

FFP 既作用係係任何放大率下D十字線刻度既比例都係保持不變,譬如枝槍打100 米要瞄高一格,有FFP 既話就係任何放大率下都可以用呢個規則,冇 FFP 既話呢個規則只可以係單一放大率適用。呢枝鏡個十字線係冇任何刻度,FFP 係完全冇作用
