Crocus Bokeh

I have numerous old manual M42 type lenses that I've 'acquired' over the years, and with the addition of an adapter, I use them on my Fuji cameras, especially for the dreamy Bokeh that they produce when taking close-up images, like this one.
My Fuji has a 'Peak focussing' setting that helps me get a sharp focus in at least one spot, but I particularly like the smoothness that is created everywhere else, this one of a crocus centre taken with a Zeiss Flektogon 35mm lens.
For the technically-minded, the F number was really 2.8 at 3inches distance, but in manual the setting never shows true readings!
