Zeiss Batis APO Sonnar 135mm f/2.8 Lens Review
As written above, Zeiss Batis 135/2.8 is apochromatic lens, reducing lateral color aberration to the minimum. There is however also longitudinal (axial) color aberration that plays important role in the lens performance, especially in the transitions between in focus and out of focus areas.
As you should see, LoCA is also corrected very, very well. This correction is equal or slightly better than Samyang 135/2.0 and clearly better than other tested lenses. I was surprised to see Canon EF 135/2 L holding quite well in this respect. LoCA festival can be seen with old Zeiss Sonnar 135/2.8 in CA mount and nothing less than fireworks with Sony SAL 135/1.8 ZA.
Bellows are few images from the real life, where I tried to push Batis 135/2.8 to its correction limits. After real torture, I was able to find a traces of yellowish color shift, but in the practice I doubt you will ever sees it.
There are very few lenses all around that will render this type of images without pronounced color aberration (usually purple fringing). This is stellar performance of the new Batis.
All images bellow where post processed to our liking. They should not be considered as a merit for the lens pure optical performance, but they should help you to recognize, what can be achieved as a final output.
