This was such an impressive cave to tour! You begin by walking down a long, spiral walkway and then follow the long tunnel into various parts of the cave. There are the typical stalagmites and stalactites but also flowing, curtain like formations as well. The glowworms were fascinating florescent dots overhead in the dark rooms. A river below had blackwater rafting options for those who were willing to don wetsuits. I'm pleased with how my new camera did in this very dark cave.
@taffy -- and it was also using my favorite lens ever since I switched to the full frame. That 50mm was hardly ever on my cropped sensor camera but now I love it.
@jyokota My 50 won't work on my new camera body and I'm so frustrated. Called the store and they can't figure out over the phone why not. So, no 50 til the end of next month! I'm so impressed with this shot it's making me more upset!!
