Agapanthus

I’ve been wondering is]f the relative lack of sharpness I’ve been finding wide-open with the DA 21 might relate to the lower shutter speeds I’ve allowed myself to use (and really have been getting away with). Hence this photo … which I think supports my hypothesis, as it is as sharp (here, wide-open) as any of my other lenses stopped down bar the eye-slicer that is the Sigma 30mm f1/4
