解像力（Resolution）

指的是鏡頭對(duì)拍攝物成像在底（相）片后的還原能力。

反差（Contrast）

指明暗對(duì)比所造成的清淅范圍大小，在彩色來(lái)說(shuō)還有所謂的色彩濃淡的分色能力。能夠容納明暗對(duì)比越大的鏡頭其所表現(xiàn)的細(xì)節(jié)越豐富，相反的如果所拍出的作品如果對(duì)比反差很大但沒(méi)什么細(xì)節(jié)的鏡頭就不是一個(gè)透光性很好的鏡頭。

光斑（Flare）

鏡頭內(nèi)因鏡筒或鏡片反射所產(chǎn)生的光線到達(dá)底片后造成畫(huà)面灰朦的感覺(jué)（所謂的翳霧）降低了作品的清淅度這就是所謂的耀光或光斑了。

鬼影（Ghost Image）

這是一種在強(qiáng)光進(jìn)入鏡頭后一排暈開(kāi)的光斑的現(xiàn)象，像是幽靈一樣的鬼影所以取名為鬼 影。

在光線通過(guò)鏡片時(shí)因介質(zhì)不同所以會(huì)有不同的折射率而鏡片與空氣接觸的界面上約有5％的光線反射，而這個(gè)反射也是光斑跟鬼影所以產(chǎn)生的由來(lái)，為了使這種反射不至于影響鏡片透光率的減少所作的處理，這種加膜的處理就叫做渡膜。渡膜的處理是針對(duì)不同折射率的鏡 片施于折射率開(kāi)√的物質(zhì)以真空蒸著法（Vacuum Vapro Deposition）渡上一層如氟化鎂(Mi F2)或氟化鈣(CaF2 )的物質(zhì)使之增加波長(zhǎng)的1/4厚度。

然而一般太陽(yáng)的光線內(nèi)含有多種波長(zhǎng)的光線而非單一的所以針對(duì)多重波長(zhǎng)所做渡膜稱(chēng)之 為多重熏膜（Multi-layer Coating）其反射率可下降至0.2-0.3％左右。
