And, just along from the Lennon wall is...

Leica M9 + 35mm Leica Summilux M f1:1.4. ISO 160, 1/500s at f1:2.8. PP in LR and Nik ColorFX 4.
 
An interesting view, Pete. A secure view. :) How many blades does the 35mm Leica Summilux has?
 
Nice shot again, Pete. I thought it was one of the 3 lovelock bridges in Paris that the streettogs seem to like, then remembered you'd been in Prague in the previous pics.
 
Pete, thanks for the honor. I am not sure if I can handle the name's weight. :)

Any idea between a 9 an 15 blade Leica lens bokeh differences. I noticed that 1950s collapsible Elmar has 15 (I think) blades. Newer models are with less blades. I wonder why?
 
Oops, sorry Nihat. I think it probably just shows that smooth OOF areas are not just a function of the number of blades on on aperture diaphragm. I have LF lenses that are wonderfully smooth and have virtually square holes! I guess also cost must come into play (although that is rarely a consideration for Leica I would have though). I have some old Taylor Hobson lenses with so many blades I can't count them!
