Though the updated processor doesn't necessarily deliver significantly better images at higher ISOs, the Canon PowerShot SX280 HS' results are better than those of its predecessor, the SX260. The SX280's photos still get softer and noisier above ISO 200 (pixel peepers will see noise and soft details below ISO 200), but its higher ISOs are a bit more usable at larger sizes.
The noise and noise reduction are well balanced so you still get very good color and detail at these higher sensitivities. Colors desaturate some at ISO 1600 and 3200, subjects look very soft, and detail is greatly diminished, but photos are somewhat usable at small sizes. Basically, if you need to shoot in low light or want to freeze action, the SX280 HS is a fine choice. Keep in mind, though, this is still a small-sensor camera and can't match the quality of a digital SLR or interchangeable-lens compact. View larger.
