Imaging Resource recently posted a review of the Nikon L15.

Overall, the Nikon Coolpix L15 performed well in terms of exposure and color accuracy outdoors. However, detail definition and noise performance were disappointing when the camera needed to raise the ISO setting. Under brighter conditions, the Nikon L15 captured much better detail. You’ll get the best results when shooting in good lighting, but expect higher noise and noise suppression when shooting at lower light levels without the flash.
