I got out to the Getty Museum, up on the hill above the Sepulveda Pass in L.A. Lovely day there today -- warm but not oppressive, and best -- no big Santa Ana winds!
Only Used it 2 times .. but obviously it seems to be performing well .. don't think it's dull AF and good bokeh for a 1.8 and clearly sharp wide open
Have not done a decentering test ... maybe I will not do that either .. are you satisfied with what it's performing so maybe you'll should stop looking for errors
It's a difference with a wide angle lens.. I think (my opinion though ).. understands all who want top ex and it should perform well ..that's what you pay for ... Haha may have to go out and do the test
One more ( sry for the size )

Really impressed with how clean the SR app stacks the images, this is 128 1/15 exposures. Just love this app, so powerful with lenses that don't like filters.
