Lillies in the RAW

A shot I took last year of a garden Lilly, using my first 'ebay' lens, a Pentacon 30mm f/3.5 M42. I've only more recently got the hang of RAW development in PDCU4 so had another look at this shot. I think it was taken at f/5.6. Hand held.

I was prompted to look again at these shots after seeing a Forum thread on "30 - 35mm lenses"
