I really wanted to see how my 50mm 1.2 lens would fare at the aquarium. I understand the lighting in the aquarium has to be low to emulate the ocean. Since fish will not pose for you, I actually had to put my setting on continuous mode.
The following 3 are a sequence of this little one as I tried to track him/her.
Humuhumunukunukuapua`a is our state fish - it is a reef triggerfish. I think this is the most elusive fish to photograph. It moves so quickly and turns on a dime!!!
Was it a challenge? Yes, despite having a very nice lens: low light, moving objects. Did I enjoy the aquarium? Yes, fish have beautiful colors and markings.
