And I also believe them to be rounded, so not the same harsh bokeh as the Canon 50/1.8
You are right about the number, thanks for the correction. I am pretty sure they are not rounded though, as I remember getting hexagonal oof highlights stopped down a little, although I have sold my copies (and kept the fa50 1.4) so I can't check right now. Can a current owner of this lens either confirm or deny?
It really isn't that big of a deal though, it (the 1.7) is a very sharp, nice, fast lens that is relatively inexpensive on the used market for someone who wants an autofocus fast fifty.
