Contax Zeiss Sonnar 85mm f/2.8
Contax/Yashica (C/Y)
Overview
The Contax Zeiss Sonnar 85mm f/2.8 is the budget-friendly alternative to the legendary f/1.4 Planar. Based on the classic Sonnar design pioneered by Zeiss in the 1930s, this lens offers excellent image quality in a smaller, lighter package. While it lacks the f/1.4's dreamy wide-open look, many photographers prefer its sharper, more controlled rendering. It's the practical choice for those who value results over bragging rights.
Verdict: The practical photographer's portrait Zeiss. You sacrifice a stop and some bokeh, but gain sharpness, size, and hundreds of dollars. For daylight portraiture and controlled situations, this delivers 90% of the Zeiss magic at a fraction of the price.
