Repaired DFA 100 2.8 Macro

My DFA 100 2.8 Macro WR was suffering with a sticky aperture return.
Prompted by a lead elsewhere on this Forum I contacted 1st Aid Repairs and got an online quote.
I sent them the lens and got it back yesterday.
They were very efficient and helpful - emailing me when they received the lens and returning by next day courier.
Eager to try the lens I took a few shots in the garden yesterday.
I've posted one of rosebuds on the Gallery but here is one of a Winter Pansy that has been in flower since last October.



I also viewed the image as 'actual pixels' and was amazed by what I saw so here is a centre crop from that level



Are these little clear sacs the result of them having shed the pollen ?

NB these are camera jpg shots taken hand held and using AF.

All c & c welcome

I've noticed (and photographed) these too. The flies appear to be encouraged to enter the flower to get their goodies and in so doing, have to pass these curtain affairs. My guess is that they sweep off any pollen present on the visitor and move it to where it's wanted. Most flower pistils have similar arrays of sticky-out bits that transport captured pollen to the middle and thence down inside the pistil tube. I'm no botanist and so could be talking utter bilge!

Could the crystalline looking transparent structure be nectar?
