Lens Barrel Flares

I discovered this lens flare effect while experimenting with a 6.5mm d-mount lens original designed for an 8mm film camera. Mounted on my Panasonic GH5 macro 4/3 camera only a small portion of the sensor is exposed with focused light. When pointing the camera at the sun the result is a unique colorful lens flare that extends into the dark vignette of the lens barrel. The result is magic.
