Thanks for the quick assessment. All seem good to great. I have to admit being most impressed with the f/1.8 and f/1.2. The f/1.8 just because that is some great bokeh for the price it is at. The f/1.2 is the best rendered image, IMO, and the cat's eye bokeh holds off until closer to the edges. But it does have flaws. Not only do you see the cat's eye/lemon bokeh, but the ends of some of the lemons are clipped. I hadn't noticed that in other test images before. But the rendering I am liking is less about the lights and more about the door frame.
As for the causes of the clipping, I'd be curious if someone has a clear understanding. Mine is a bit rudimentary, but generally, light hitting the front element's center may be perfect circular, but two things can happen as you move to the side of the front element, 1) the view of the circle is not at a slight angle, which will make circles become ellipses and 2)
this is made worse by a curved front element. Is that about right? The clipping tells me there is some physical object in the lens clipping the edges of the light at the widest apertures. That used to happen in mirror boxes of DSLRs, I am curious about on a mirrorless body.
Anyway, thanks again. BTW, I really do not think the onioning on the f/1.4 is all that bad. Certainly not as bad as some zooms's I've seen. 3 good lenses as far as I am concerned.
Edit: I found this write up on
optical vignetting. It covers everything but the curve of the front element.
B&H has a brief write up that attributes it to the degree of light being bent. I am thinking this has less to do about the front element which, thinking about it, that would bend the light in a way to point the light towards center, not perpendicular to center. So I struck that above.
