Horrifying spherical aberration wide-open.

Good to know!

Made in Germany, impeccable construction quality no doubt, though I
don't know anything about the actual design. More images are needed to
evaluate the thing. Also, they said "round" bokeh (as in lights?) but
the portrait of the blond woman shows the typical ovoid shapes we see
from many fast lenses.


That's cateyes! They reflect the shape of the aperture at the edges of
the captures. The Sigma 85/1.4 has got some flac for that too... The
Meyer have multiple aperture blades but that won't help them out with
this issue. My Schneider 300/5.6, MF no IS has that to but I've never
goy around to stop it down that much so that I can study the effect.
Maybe at me next visit to them African plains! :-))

It's a form of astimatism. If you have the lights as point sources
in-focus at the edge of the field, you can see the distortion.


At the edge of the image the whole aperture ain't in the path of the
light and that is that that's causing the effect. Just like the classic
hexagon bokeh reflects the six blades of the aperture. Those lenses do
not need to be astigmatic when the subject is in focus.

Some folks crave it!
