It's a high detailed photoreallistic DSLR Lens, Leica Summilux-M 50mm ASPH
You can use Max 2010~2013 for rendering with Maxwell render and V-Ray.
You can also use FBX, OBJ, 3DS format for Polygonal tools
and 3dm, SAT for Nurbs modeler.
In case of FBX, there are two version included (N-gons & Triangles mesh)
If you use FBX2013.3 version, it's compatible with Maxwell material.
In .Max and .3DM file, there are the same named layers embeded.
So if you need more subdivided mesh for some parts, you can easily change it from original Nurbs model.
In my case, I used 3DM->FBX->3dsMax converting process.
Camera setting, 4 bitmap textures are a HDRI(800x400) is included with Studio Lighting Seup.
Objects / Polygon / Vertex count is (case of max2013 file) ;
