This is an experiment with extreme macro.
A 300mm zoom lens with an inverted 28mm prime mounted in front gives a field of view around 2 mm wide on the APS-C sized sensor (300/28 =10.7:1 magnification, or over 10 times closer than a normal macro lens).
The setup is slightly disappointing because the depth of field is extremely narrow, making focusing very hard, even at small apertures. This is f13.
Rough focus manually on the zoom, tuned with a focusing rail on the tripod.
Oh, and the subject is connectors on a computer chip. They look like silver strands of hair to the naked eye.
