I'm using an Olympus TG-5 hand-held. It has a 'microscope' mode so it can take macro photos without a special lens. It is an underwater camera so it has a tendency to overexpose the photos and this has to be adjusted in a program. I tend to destroy a lot of cameras in my adventures, so I like the waterproof/tough features that are built-in.
It will also take around 30 seconds of high speed video with a fast memory card, but, because the shutter speed is so fast the light entering the aperture/second is reduced drastically so everything appears dark. Here is me on the business end of a defensive strike (@420fps).
