The Zeiss Touit 32mm f/1.8 is not that great. Image center is sharp straight from the max. aperture and even stunning when stopping down. Borders arenít all that interesting at large apertures although at least very decent beyond f/4. Lateral CAs are visible without being disturbing. Distortions auto-corrected either by the camera or your favorite RAW converter. When looking behind the scenes, higher than expected issues can be spotted here Ė a bit disappointing for a pricey Zeiss lens. Vignetting is also on the high side at fully open aperture. Given its max. aperture of f/1.8, the Touit is obviously meant for speed so itís good to see that the bokeh is of high quality and well controlled bokeh fringing.
