You're welcome. I couldn't shoot straight on to the wall as I was getting my reflection in the center window, so the distortion you're seeing is a combination of barrel distortion and keystoning from the angle I was shooting at. There's also probably a bit of off-axis tilt as well, it is a hand held shot. I've done a pass at correcting it by a sequence of changes...
Of course, the old church is such that there are hardly any truly square lines anyway. I wouldn't panic based on this brick wall! But yes, the DA21 has a bit of barrel distortion. More than the DA14, but then the DA14 is intended, I think, as an ultrawide rectilinear for architectural work and *should* be nearly distortion free. The DA21 is more of a general purpose wide-angle lens ... I find the barrel distortion is only an annoyance on occasion.
