There's a complete review on the Samsung Digimax Pro 815 by CNET where they state, 'The Samsung Digimax Pro 815's performance was less than stellar in our tests. It took 2.2 seconds to start up and capture its first image, and images thereafter took 1.8 seconds without flash and 2.6 seconds with flash. But those sluggish numbers don't tell the whole story, since those refer to capturing JPEG images. Once you switch to raw or TIFF, things get really slow. The Pro 815 took 18.7 seconds between raw images, and a horrifically slow 28 seconds between TIFFs. Continuous shooting wasn't very fast either. At full resolution, the camera captured an average of 0.64fps, though it jumped to 2.62fps when capturing VGA resolution stills.' 'Given its flaws, it's difficult to recommend the Samsung Digimax Pro 815.'
