The group at CNET review the Casio Exilim EX-Z1000 where they say, 'Despite a very responsive shutter, the Casio Exilim EX-Z1000 takes just a bit too long between shots. After a quick 1.8 seconds from power-on to first shot, the camera took 3.5 seconds between every additional shot--even though shutter lag in bright light was a minimal 0.3 second and only 0.5 second in dim light. With the onboard flash enabled, that sluggish rate ballooned to 5.1 seconds between shots. The camera's 8MB buffer isn't enough to handle the burst throughput required by 10-megapixel images, so the EX-Z1000 had poorer continuous-shooting performance than other snapshot cameras: 0.4 full-resolution frame per second. You have a variety of options that can deliver speedier burst results, however.'
