Frozen motion

Facinating to my eye. All shots taken with Leica M9 + Summilux 50mm. I forgot I had the ISO set at 800, which is the cause of the noise. Shutter speed was 1/4000 and aperture most likely to have been f/1.4. Why buy a Summilux to use it at anything but wide open? Which reminds me that I’ve just bought a 3 stop ND filter to use in sunlight. Will post some example shots soon.
