Absolutely. This is why I encourage others to think about the kinds of
subjects they wish to shoot with extreme wide angles. While the Zuiko 28/2.0
shows almost no distortion of any kind, it's probably the "last" in the lineup
with this admirable quality. As you proceed further towards super-wide-angle,
various distortions almost inevitably get introduced. The 21/2.0 has
distortion -- but if you choose your subject correctly, you won't normally
notice it...
