Great effect, @bobriess !
I didn't know this Canon had 5 aperture blades. Did you have a tripod or is this taken "handheld"?Thanks, @Mike7 – I enjoy your mono street work as well...
Yes 5 blades, probably my youngest manual lens – I'll get in a legacy mood some days and grab this one or the "Japanese Summicron" Canon LTM50 1:1.4 or the Elmar 50. This was handheld, I keep the tripods for portraits, some landscapes and astro, I'd have my head handed to me if I set up in the Metro or other crowded places...I didn't know this Canon had 5 aperture blades.
