I own a 50 ZE f:1.4, and it is my favorite lens. I shoot primarily landscape/cityscape, and some portrait, and it is my go-to walkabout lens. Not expensive by Zeiss standards, light and unobrusive. It has one weakness, up close and wide open, for which it is clearly not optimized. But everything else is a delight. Colours, contrast, 3D are all world-class. Of course, being an MF lens, shooting moving targets is not on the menu...
