Colour reproduction in JPEGs taken straight out of the camera is spot-on, with vibrant yet faithful hues remaining true to life under most conditions.
While noise is fairly well suppressed at mid-high ISO sensitivities, the camera's noise reduction system can sadly also rob shots of fine detail when viewing shots at 100% or printing at larger sizes.
The Sony TX20 doesn't sport the closest focusing capabilities that we've seen, but still manages to do a pretty good job of capturing frame-filling close-ups and abstract shots.
The Sony Cyber-Shot TX20's Auto White Balance system performs pretty well under most lighting conditions, meaning there's often little need to adjust colours post-shoot.
In spite of some softness around the edges of the frame being a common feature, centre-sharpness in shots can be very good indeed.
The camera's AF system slows down in dim conditions, but the camera's image stabilisation feature helps to keep moderate levels of camera shake at bay, and colour reproduction remains very good.
