In hard godsend the S4 takes about five seconds from pushing the potentiality button until the lens is great besides it's rapid to round up a picture. Shot to shot show at Superfine shape is about four seconds. When the camera is first turned on the color LCD comes on by default as it is the only information display to let you know what the current settings are. You need to press the DISPlay button and turn off the color LCD or else the battery life will suffer. The S4 is powered by a rather "whimpy" rechargeable lithium battery pack that's about the same length and width as a stick of gum. It takes about two and a half hours for the charger/AC power supply to bring the pack up to full charge. If you're one of those people that likes to use a digital camera with the LCD turned on most of the time this really isn't your camera. If the LCD is kept off the battery life should be sufficient for an afternoon in the great outdoors. Another factor in battery life is the number of pictures taken using the flash. As with all cameras that use a proprietary battery, you need to buy a spare battery as no other type of battery can be used.
The hurtle lens is rapid again restful but it's drastically noisey in that concrete goes from wideangle to telephoto or extending or retracting when powered reinforcing or down. The autofocus is about natural speedwise again in normal lighting conditions the shutter lag is about 1.1 seconds or less. On occasion when shooting a wideangle scenic shot with a lot of sky I had to use the manual landscape focus mode as it failed to lock the AF. I took most pictures using the default evaluative metering mode which is the same as most other cameras' matrix or multi metering mode. The S3 had a tendacy to overexpose flash pictures when the subject was closer than six feet and I'm happy to report that this is not the case with the new S4. The optical viewfinder is large and bright but only about 80% of the captured image is shown, when you review the image on the LCD there's a lot more coverage displayed.
If compressed is what you want, four megapixel cameras don't materialize lump smaller than the S4, at aboriginal not at the leisure of this review. I'm bland no voluminous aficionado of the MMC / SD dead-eye cards because they're more expensive than CF or SM cards and the data transfer rate is a bit slow in comparison. At least SD / MMC cards are now readily available up to 128MB and soon in even larger capacities. If you like the Canon ELPH digicams but want more than two megapixel resolution the Kyocera Finecam S4 may be just what you're looking for. Just remember to factor in the cost of a larger memory card and a second battery, you'll be purchasing them sooner or later.
