The Stylus TG-2 features a fully internal 4x optical zoom lens with a 35mm equivalent of 25-100mm. With a maximum aperture of f/2.0, the camera does very well with low-light situations, which is vital for shooting underwater. It also features Sensor-shift optical image stabilization, which is another plus for any situation in which you may not be able to hold the camera completely still. The removable red ring above covers the mount for adding the fisheye or telephoto lens adapters.
Normal Mode: W/T: 0.1m-∞
Super Macro Mode: 0.01 - 0.1m
Working with the low-light lens is a 12-Megapixel Backside Illuminated CMOS image sensor and TruePic VI processor, which help to reduce image noise, especially in low-light. They also create the excellent performance that the camera is capable of.
The flash unit on the TG-2 is small and not very powerful at all. With a range of up to approx. 26ft. (W) at ISO 1600, it is mostly useful at close ranges. Next to the flash is a LED video light, which will stay on while you are recording video. It can also be turned on for macro shooting.
Framing and viewing your images is accomplished with the 3.0-inch, 610,000 dot OLED screen. It features several levels of brightness and several protective coatings which also help to cut down on glare and reflections. This makes it surprisingly easy to see and use in all lighting conditions.
Controls on Back: At the top you have the zoom control buttons. Next is the dedicated Movie Record button on the left. To the right of it you will find the camera's mode dial. Directly under the video recording button you will find the payback button. Pressing the 4-way controller up changes the amount of info you see on the screen while shooting or viewing your images. Pressing down allows you to delete images in Playback mode. In Rec. mode the up changes the amount of information on the LCD, right handles the flash settings and down the self-timer. At the bottom you have the MENU button.
On the left side of the camera you will find your input/output ports, hidden behind the TG-2's waterproof door. This door has rubber seals to keep out water up to the specified depth. Inside you will find two ports, USB 2.0 on the bottom and a mini HDMI port for viewing your images and HD Movies on a HDTV on top.
Here is a better look at one of the waterproof gaskets that keep the camera waterproof. This seals the door for both the battery/SD card and the I/O ports. On the reverse side, there is a switch and a lock to make sure that the doors are sealed before you go into the water.
The TG-2 stores its images on any SD/SDHC/SDXC memory card. With the camera's high speed image capture and full 1080p video capture, you will want to use the fastest card you can get your hands on. The camera is shown here with the SanDisk Extreme Pro 8GB card that it was tested with.
Powering the TG-2 is a 3.6V, 1270mAh rechargeable Li-Ion battery. Olympus claims that the camera is capable of capturing approx. 300 images on a single charge, depending its use. Since the camera is charged via USB, it is a little harder to keep a spare battery charged, but there is no external charger to carry around.
