built in flash. I didnt have a tripod with me when i was on the beach, I was resting the camera on a plank of drift wood lol
Alot of night shots that I took, I took without a flash as I was trying to learn how to use the camera.. thats why they are under exposed. Also I wasnt allowed to use a flash for the aquarium shots, but I started using it half way thru anyway.
I have posted what lenses im using in here somewhere, but its 6am and Im to tired to remember right now or look for them haha
