Chromatic aberration wasn’t much of a problem with full-frame competitors. Nikkor 2/35 held within range of 0.04-0.10%, Canon within 0.05%-0.09% and in Zeiss 2/35 rose from 0.4 to nearly 0.15%. Sadly, the level of the defect is higher with Nikkor 1.8/35 DX and changes from 0.13% when wide open to 0.17% when stopped down. This last value represents a high level easily noticed in photographs.
It’s heartening that the Nikkor’s potential rival, Sigma 1.4/30 resulted in practically equal defect of 0.16-0.17%.
