This is one of my favorite lenses that I own. I use it daily on my Canon 5DMKII.

The lens is very high poly and thus highly detailed and accurate. The scene included is for V-Ray but I've included the textures so you can easily prepare it for different renderers.

If you want to use your own materials, use the included bmp as diffuse color (it's not 100% black!) but other than that you're good to go.
