Fujifilm Finepix S5 Pro processor’s two stages of noise reduction delivers an impeccably clean image, and also permits light sensitivity up to ISO 3200 while still achieving sharp, low-noise images. Furthermore, dark noise reduction process, subtracting the residual, ambient noise on the sensor from the actual exposure, helps the camera produce smooth, clean images when long shutter speeds are used.
For flash photography, the Fujifilm Finepix S2 Pro features a pop-up flash as well as a hot shoe for connecting a more powerful external flash unit. The built-in flash works in several modes, including Auto, On, Off, Anti Redeye, Anti Redeye with Slow Sync, normal Slow Sync, and Rear-Curtain Sync. In Self-Timer mode, a self-timer counts down from two to twenty seconds before firing the shutter, flashing the AF assist light on the front of the camera during the countdown.
