Hi everyone, I just visited our 'oceanarium', Underwater World Singapore over the weekend.
I used the 24 - 105 F4 L lens mainly. The glass at Underwater World makes it hard to shoot as most of it is either concave or convex, my guess is that it allows for easier viewing (although not necessarily for shooting video :p )
I just took some generic shots and have compiled them into a short video.
Hope you like it :)
