The Canon PowerShot SX150 IS produced good results in the labs tests, showing that its signal to noise ratio is on par with the Panasonic Lumix TZ-20 and Samsung WB700.
For a compact camera, the amount of noise that actually appears in your images across the sensitivity range is average. Dynamic range results from the Canon PowerShot SX150 IS also show a good performance with consistant values across the sensitivity range.
A highlight of this camera is the above average performance, with less of a drop in dynamic range than you'd expect from a compact model, showing that this camera is capable of good low light photography and in normal shooting conditions will capture a good amount of both shadow and highlight detail.
