I've just come from a vacation trip where one of the attractions was firefly watching at night. I only brought with me my point-and-shoot camera, a Canon S100, but to much disappointment, I wasn't even able to photograph the little critters; they did not even show up on my camera's EVF! So, given that my camera was useless at that time, I tucked it away. That was some time ago.
Now, I got a Canon 70D. I also have the Canon 40mm f2.8 lens. If ever I do go back, are these two enough to take some photos of the fireflies?
Here's an interesting stipulation: the attraction takes place in a river and the tourists all sit in a boat, and only a very dim red light by the guide, stars, and the moon provide light, apart from the fireflies. Since there's no place to set up a tripod, I was wondering: can they even be photographed hand held? Is the 70d and the 40mm enough?
