Tominon made a 26.9mm f4.5 lipstick size lens that has some inscriptions about macro reproduction ratio. With all the extensions (PB-5 plus 115mm) a photo of a ruler shows about 1.7mm wide on APS-C.

Can anyone tell whether this lens might have an aspherical element, is it a typical Tominon Tessar or something else entirely?

#1 Tominon lens mounted to a Nikon PB-5 Bellows using a M42 adapter that I printed up. The backside of the adapter has not been flocked loss of contrast and light leak is expected.

#2 Sample Photo APS-C. Using Nikon PB-5 with 115mm Extension Tube. Just a quick shot handheld in bright daylight. This is hair on the skin of a fly.
