Oh and just for clarity, when I said I shoot stopped down, I wasn't talking ƒ8, I was talking ƒ2-ƒ4 for many shots. If it had been a ƒ2 lens I'd still have all but one or two of the images I've taken with it. To me, the big advantage to ƒ1.4 is focussing in low light, and that's always on line. I tried shooting ƒ1.4, I didn't like the images...
However that is my one of maybe 5 ƒ1.4 keepers taken with the lens, and they were test shots.
Another one...
At ƒ4 (normally as low as I go...
And at ƒ5.6
Even I'm willing to admit, that bokeh is a little squirrelly, (sorry for the technical language) the DFA 50 1.4 would have almost certainly have done better. But if you can manages the out of focus areas, Bob's your uncle.
In any case, that should show you what you'd be dealing with.
Meanwhile at ƒ8.... it's fantastic
