The lens has one flaw. Bright, point-source lights can have an asymmetrical flare artifact at any aperture. The angle of the light seems to be important. This flaw is most often seen in night scenes. There is speculation the flare is related to internal reflections as the rear element is very close to the sesnor. It is so close the sensor micro-lens design changes from the center of the sensor to the edges in order to accommodate the difference in light angles.


The lens can have flare issues when some filters are mounted. This is highly dependent on the filter. The built-in ND filter, however, causes no problems at all.


Otherwise, I really like the lens.
