This replacement Sea & Sea DX-1G Underwater Digital Camera has a shutter lag time of only 0.1, sec. so it is well suited for underwater use. The camera features a large 2.5" TFT liquid crystal monitor. This makes framing underwater easy and fun. Since the camera has manual as well as program exposure modes you have complete control of balancing the available light to strobe light. These features along with exceptional macro capability of a 1/2" make the DX-1G's functionality and performance close to an SLR without the bulk, hassle and weight.
