The working distance at 1X was 4 inches.
I am terrified of snakes LOL...but the little voice in my camera asks me to go ahead and do it. It has made me done so before and it's doing this again!
The first snake image was shot with an MPE65.
Edit: my second snake shot with the MPE65:
Dendrelaphis striatus, Cohn's bronze back snake.
My third MPE65 snake portrait: Tropidoleamus subannulatus, formerly a subspecies of wagleri but now has full species status
I got a 2x shot of it too:
Me photographing a mock viper, Psammodynastes pulverulentus
Paradise tree snake (Chrysopelea paradisi). 150mm with 1.4x teleconverter.
Keel-bellied whip snake (Dryophiops rubescens)
Pink Head Reed Snake (Calamaria schlegeli)
