50 mm prime-lens 3d model

.: What is a prime lens? :. In film and photography, a prime lens is either a photographic lens whose focal length is fixed, as opposed to a zoom lens, or it is the primary lens in a combination lens system. Confusion can sometimes result due to the two meanings of the term if the context does not make the interpretation clear. Alternative terms primary focal length, fixed focal length, and FFL are sometimes used to avoid ambiguity. || 3D Model of a 50mm Fixed Prime Lens || This is a 3D model of a 50mm fixed prime lens - Originally created with 3ds Max 2012 - 56984 without Turbosmooth - 393506 with Turbosmooth - All Materials are procedural Mental Ray materials - Inside of the lens is modeled. || USAGE || - This model is suitable for use in broadcast, high-res film close-ups, advertising, design visualization. - For performance purposes I kept the turbosmooth level at 2.
