K20D

General Description

Being the successor of the popular K10D, the body design of the K20D remained almost unchanged. However, the image sensor of the K10D was replaced by a new sensor with higher resolution and from another manufacturer: Samsung. Samsung also presented a twin camera model, the Samsung GX20.

The K20D was the first Pentax offering AF fine adjustment for up to 20 lenses to avoid front/back focus problems.
