Bubbles, just bokeh bubbles
This abstract is composed of bokeh bubbles of Christmas tree lights, taken with a fully open f/0.7 aperture lens.
The fastest lens I have in my vintage lens collection is an ultrafast f/0.7 X-ray lens, the Canon Lens X 60mm f/0.7. This lens was used in X-ray machines before the digital area. This lens is a tank, weighting 2.7 kg. Front diameter is 101 mm, back 55 mm. The flange focal distance is less than 10 mm, e.g. too short for Sony E-mount, which is 18 mm.
I simply used duct tape to attach the camera to the lens, works great, and is surprisingly sturdy. With this setup the focus distance is about 19.5 cm. So this lens has a fixed focus distance, can't focus to infinity, and is always fully open. The depth of field is around 2 mm, so it is very difficult to focus. This lens is so fast, I used ISO 200 and 1/90 sec for this bokeh shot. The Christmas tree is about 1 m (3 feet) from the camera. Each light on the tree turns into a big bokeh bubble, bigger than the sensor, which is full frame.

This lens is as fast as the legendary Carl Zeiss Planar 50mm f/0.7, that was made for NASA, and was used by Stanley Kubrick to shoot his film Barry Lyndon: bit.ly/2LpV0WY
I processed a soft HDR photo from a RAW exposure, and carefully adjusted the color balance and curves. I welcome and appreciate constructive comments.
