When I have to take a photo with smaller aperture and zoom I always get a weird green dot in the center of the image. Please, advice what causes this artifact and a proper way to avoid or fix it.
Camera: Sony Alpha 6000,
Lens: E3.5-5.6/PZ 16-50 OSS 0.25m/0.82ft-0.30m/0.98ft d40.5
This lights gives exactly same results:
- No special setup, just room with 6 led ceiling lights and window (cloudy, no sunlight)
- Carton box with top+left+right (diffused) + ambient light from room ceiling lights (no windows, no sunlight)

I do not use any filters, only camera with kit (standard) optics and on camera flash This photo sample is item on white A4 paper sheet. It is zoomed to occupy all space.
