Ilex Oscillo Panagon 75mm 1.9 (3 inch)
First shots from this $50 oscilloscope lens! And my jury-rigged setup. My stacked helicoids give infinity or near-infinity, but a really long working distance when close focusing… It seems to get sharper when I fully extend both helicoids, and the working distance gets a bit shorter. I assume this lens is really designed to be very close to the subject for real sharpness. Lots to play with!
