Thanks so much for your comments, guys! After a whole month of photographing FiR's ultra-smooth, unreflective, matte-finished IEMs, going back to glossy, mirror-like lacquer was a harsh, harsh reality check for me.
But, in the end, I'm pretty happy with how it turned out, and I'm glad you are too.
One note I'd make about IEMs and macro lenses: Dust. So. Much.
Dust. If you plan to go 80-100mm, be ready to get pretty thorough with a microfibre cloth or
very creative with Photoshop's
Clone Stamp tool. The devil, as they say, is in the details.
