@molizard Canon 100mm 2.8L for this one, I've got the 180mm 3.5L as well as the Kenko extension tube set. I also got an adapter to reverse mount an old fd mount 50mm 1.8. Been experimenting with lighting, starting to setup with a tripod and will probably snag a focus rail to do image combined focus stacked shots. I'm a lab rat, worked in UC research labs for 20 years.
