Prepare yourself for a new style of expression where you can hold light in your hand. Introducing the PENTAX K-S1.

Resolution and moiré reduction, two uses in one

Anti-Aliasing Filter Simulator

The low-pass filterless design maximizes resolution from the CMOS image sensor. This model is also equipped with the PENTAX-original Anti-Aliasing Filter Simulator function which reduces moiré that occurs due to tiny drive operations of the sensor. Two merits are obtained from this one unit.

* Sufficient effects are obtained when shooting at shutter speeds slower than 1/1000 sec. Also, this function cannot be used when taking "HDR" photos.
