Ah, and one thing I forgot to mention is that my lens was set to "macro" mode (that mode the Sigma lenses can take up when extended to between 200 and 300mm), which accounts for the background blurriness, even at f29).
Awww :hugs: thanks all. Makes me happy :goodvibe: to see that someone is out there who likes these.
The phenomenon as such is one that never fails to fascinate me, i.e. the sun shining through the droplets in our trees and bushes!
