Chromatic aberration will give us no serious reasons to complain at the ends of the focal lengths range. At 16 mm it keeps the level of 0.08-0.09% more or less, which is considered to be low. At 35 mm the results are even better. When wide open the aberration is totally imperceptible and it increases to 0.09% only on significant stopping down. In the middle of the range and wide open the performance is beyond reproach. You can start complaining only on stopping down by 1-2 stops because then the aberration increases to higher medium levels reaching values of 0.13-0.14%. To sum up the lens deserves a praise in this category, taking into account, of course, its fastness and wide angles of view.
