I am a recent convert to the religion of Zeiss, and my initial experience suggests that I will be keeping the faith for a long time to come.
The two Zeiss lenses currently in my bag are the ZE 50mm f/2 Makro Planar and the ZE 100mm f/2 Makro Planar, both manual focus lenses designed for the Canon EF mount. This glass is versatile and delivers exceptional image quality across a variety of regimes – Portraiture, Macro, as well as Landscape. Making photographs with such precision crafted tools is a great pleasure.
My entry into the Zeiss fold may be laid at the door of Diglloyd (aka Lloyd Chambers) and his definitive guide to Zeiss lenses (thanks Lloyd!).
Wide open at f/2, nailing the focus is critical to a successful image.
The dark patch at the top edge of the frame is a heavy monsoon cloud, not an artifact of lens vignetting.
