Zeiss 85mm ZN Sonnar Lens on a Leica M9 - Is it a Winner?

[ZagatoV12]

Hi All,
I've just completed a revised and extended review of the Zeiss f/2.0 85mm Sonnar Lens. Is anyone else using this combination and if so, what are your views? The article is at http://www.theintuitivelens.com/equipment-reviews/zeiss-85mm-f2-zm-sonnar-lens-review-revised-and-extended/ if you would like to read what I found and add your view or experiences?

Happy New Year 

Mike
