沿同一光轴拆开的相机镜头

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.

浅灰纸面上，一支相机镜头沿水平光轴展开：前环、几片厚度不同的镀膜玻璃、光圈叶片、对焦镜筒和后卡口依次悬浮，间距均匀，投下轻微阴影。精密产品分解插画，黑金属、清澈玻璃与淡蓝反光，所有部件同轴，不要箭头、编号、字或商标。
