Like Bruce said, many Zeiss lenses, known for their sharpness exhibit some vigneting (wide-angle and 50 macro) or CA (100 macro). I had a very good 2/25mm but it had severe vigneting from f:2,0 to f:4 or 5,6.
I tested several other wide-angle lenses from Zeiss and they behave similar...as you can see in some test reports.
For a good macro lens in Nikon F mount, there are some good old Nikkors, like the 3,5/55 or 2,8/55 Micro-Nikkors, the AF-AFD 2,8/60 and AFS 2,8/60.
Or with a longer focal lenght, the Nikkor Ai-Ais 4/105 or the 2,8/105 are also pretty good. Other candidates, the last Tamron 2,8/90 VC macro (better than the Nikkor 105 AFS), or the Sigma 2,8/150 with or without vibration reduction (OS optical stabilization).
Last but not least, the legendary Voigtländer Apo Lanthar 2,5/125, but this one is getting pricey !
