More than anything I got the impression from your images that contrast increases slightly on stopping down. It's a bit like my ZD 300/2.8, the difference in sharpness between f/2.8 and f/3.2 is negligible, but there is a noticeable increase in contrast and color saturation.
Also, I'm not far from calling that "sharpest wide open" thing a myth.
Looking good... is it possible for you to share full res photos? Really interested.The 17mm arrived today and I had try it out of course. After a 33 degree day the beach was the spot to be this afternoon. My daughter is a semi willing subject so grabbed a few photos before heading out for a swim. All are shot at F1.2 on my Panasonic G9.
I am really enjoying my brief time with this lens, it is expensive but the image quality at F1.2 is amazing Olympus have really nailed it.
