變形鏡 重要 嗎?

用咗變形鏡就無咗pixel to pixel
但畫面光度同臨場感都好啲
睇自已需要啦

Supposingly play blu-ray movie (with native aspect ratio of 2.35: 1),

then using anamorphic len to throw to 2.35 :1 screen with image adjusted to 2.35:1,

How is the pixel to pixel?

一般用變形鏡會先將2.35:1畫面拉長成16：9
再用變形鏡拉闊成2.35:1
而喺16：9轉2.35:1時已經令到個畫面唔係點對點
以上係一兩年前嘅玩法
樓主個變形鏡我未見過
可能有新科技我唔識

Just for sharing:
Are anamorphic lenses needed (or even beneficial) with Blu-Ray as a source?
