Jim Thanks, Akul. I was concerned that the last one's background looked a little busy.
For my eyes, the bokeh background of the last one is painterly and pleasing. If anything, it could be the sharpening for web size image contributing a bit of grain possibly ? Not really for my eyes though.
Paul - Sorry, it was ZE and not ZF. Interesting point you are making regarding the difference. For F mount, I don't have a choice to convert CY 100, so only ZF would be my option. Nonetheless, these CY images look great.
