This is my fourth Pentax SLR ... I laché my K-5 for the swiveling back, something indispensable for macro when one refuses to grovel. The quality is there, great sharpness and low noise of the sensor, but the ergonomics are reviewing at the back, because the keys are very sensitive everything is done to the base of the thumb triggers the reading or the burst. Too bright lighting and video is ... On the other hand nothing for the left hand which can only enter the body of the lens. There I regret the K-5 but not this purchase, I will have to better educate me.
