This is with the nikon 85mm lens with a 15mm spacer and +4 close up filter on my Olympus E-420, Its the first time i have captured the segments? and there's a lot of noise present so i still have a lot of work to do.
Aside from the chroma noise which you mentioned, the detail in the eyes is fabulous! The photo looks quite 3D with the curved patterns on the eyes – nice shooting!
