I'm considering buying the Zeiss Makro-Planar 50/2 as my only lens. I will be using it for macro, landscapes, video and portraits. My biggest concern is for portraits, especially the bokeh. As I have looked at photos taken with this lens the quality of bokeh sometimes looked really smooth and other times very busy.
The other option is to buy a Contax Zeiss Planar 50/1.7 and a Canon 100/2 Macro but the bokeh on the Contax seems worse than the Makro-Planar. I have had the Canon 100/2 Macro in the past, it was fine as a macro lens, not amazing but got the job done.
As things look now the Makro-Planar seems like the best choice for me. Opinions? Suggestions? I would love to see some portraits taken with the Makro-Planar if anyone has used it for that.
Thanks!
