Conclusion: The Zeiss Distagon T* 35mm f/2 ZF may not deliver superb results on full format DSLRs but the quality is still impressive. The lens is sharp straight from f/2 and especially around f/4-5.6. Lateral and longitudinal CAs are moderate, but for most subjects nothing to worry about. The moderate degree of distortions is about average for a prime lens in this class. However, a real weakness is the annoyingly high amount of vignetting at large aperture settings.
Conclusion: Quality-wise the Zeiss Distagon T* 35mm f/2 ZF is a little superior compared to its its sister lens, the Distagon T* 25mm f/2.8, and it easily outperforms the corresponding Nikkor AF 35mm f/2. The resolution in the center is about as good as it gets on the Nikon D200. The borders are very good at large apertures but it takes till about f/4 before the quality gets excellent here. The level of vignetting is about average for a lens of this class.
