Several Eastern Ringtail dragonflies (Erpetogomphus designatus) were spotted along the Potomac River at Riverbend Park, Fairfax County, Virginia USA. These individuals are male, as indicated by their terminal appendages and “indented” hind wings.

All of the photos in this set were taken using my Fujifilm X-T1 digital camera, Fujinon 100-400mm telephoto zoom lens, and Fujifilm EF-X500 shoe mount flash.

I nicknamed the Fujinon 100-400mm lens “Big Boy” because it’s so big and heavy. I use a Sunpak 6700M monopod and Vanguard SBH 100 ball head to support the lens.

Zoom in on the full-size version of the preceding photo. Notice the terminal appendages are spread apart, revealing a clear look at both the cerci and hook-shaped epiproct.

Wow. “Big Boy” helped you to capture some amazingly sharp images with great colors. Were you focusing manually for these shots, Walter?

The camera was set for manual focus but I used autofocus. Huh? My Fujifilm X-T1 features focus peaking that works when using manual focus. I discovered that focus peaking still works when using back-button autofocus. It’s the best of both worlds!
