I took all of these within moments of each other all on tripod ISO 100, I found that as I stopped down I had to compensate more, I will have to play with that more in the future.
I really wasn't impressed with f3.5 at the closest focus, nothing was spectacularly sharp, I thought it sharpened up nicely by f5.6 and f11 seemed really nice, though f22 was visibly softening again.
I hope to take some more interesting shots when it warms up and see what the bokeh is like.
