The lights on the camera are monochromatic, which boosts low-light and infrared sensitivity. They may also ease the processing of the hardware, since interference with the hardware by light sources is much less of a concern.
The camera's shooting mode is ISO 100-12000. This should give you all of the standard ISO range of the A02S, and three stops over. Above the 12000 setting, you might run into the problem of overheating, and expect to find it added to the range of ISOs available on your camera.
The lightning system will give you slow bursts of lightning, but don't expect instantaneous results. If you zoom out to macro, you can activate it manually by tapping the three light circles next to the shutter release. This can be done in either portrait or landscape mode.
The power saving mode that the Sony Larger battery comes with will decrease the average current drain by half. It's a great green feature if you're on a budget. However, it may be too much to expect to get a full day's worth of shots out of the smaller battery. d2c66b5586
