Excerpt: The 50mm Zeiss Macro joined a large number of L lens and while it takes excellent photos it does have some shortfalls. In low light it does not perform well on my 5D iii. Colors in low light are disappointing and not as good as my L lens.
Excerpt: I compared this lens to my 10 year old Nikon 50mm f/1.8 (no D) lens. I shot several photos of a couple of bouquets using both lenses. I mounted my D700 camera on a tripod, and used the same focus point with both lenses. Since this was indoors, the light didn't change much between exposures.
Excerpt: I wrote a very positive review on this site for the Nikon 55/2.8 AI-S, based on using it for thousands of shots over 30 years. I still stand by that review, but I have to say this Zeiss is in a different league. Why? 1) the color rendition is phenomenal.
