沿同一光軸拆開的相機鏡頭

On warm gray paper, explode one camera lens along a horizontal optical axis: front ring, coated glass elements of different thicknesses, aperture blades, focus barrel and rear mount in order. Even gaps and soft shadows, precise industrial illustration, black metal, clear glass and faint blue reflections. All parts coaxial. No arrows, numbers, text or logo.

淺灰紙面上，一支相機鏡頭沿水平光軸展開：前環、幾片厚度不同的鍍膜玻璃、光圈葉片、對焦鏡筒和後卡口依次懸浮，間距均勻，投下輕微陰影。精密產品分解插畫，黑金屬、清澈玻璃與淡藍反光，所有部件同軸，不要箭頭、編號、字或商標。
