None of the VC lenses have much distortion, but there is a very
slight bit; just enough that you can tell a shot with a 21 SA from a
shot with a 21 Skopar if there are straight lines near the edge. The
15 and 12 have similar levels of distortion. If you did shoot a brick
wall after setting up everything correctly the amount of distortion
you see would probably be 1/2 due to the lens and 1/2 due to the
mason/bricklayer. The lens is that good.
The 21 non-ASPH Elmarit has more distortion, and the ASPH very
slightly more than the 21 Skopar.
ALL slr lenses in this range that I have ever tried have more
distortion than the Skopar or 21 ASPH, or the 15 VC. I've not tried
the current 19 Elmarit or 15/2.8.
