megapixels

Quite an amazing camera for the size. This Kyocera is capable of producing some fine detail in photos and does all this with speed that is usually not found in smaller pocket units.
I normally use the large Sony 828 which is far removed from a pocket camera but Kyocera gives many of the features of a mid range camera in a compact size. The Kyocera SL400R fills the need for a smaller unit and at 4MP it can produce close to the same quality for routine use. Focus can sometimes present a challenge but overall, this is worth a look. For it's size and capabilites, this Kyocera is gives an easy five-star performance.

First off, I'm extremely pleased with this little camera. Does it have shortfalls? Yes, but not many. I bought this camera for specific reasons and it performs 100% of what I want it to do.
I'm in the military and on the go quite a bit so I needed something small and easy to use.
One of the biggest pluses (to me) is not needing a tripod. The swivel body is perfect for setting about anywhere and getting the shot (of myself) wherever I am. No more balancing my camera on a pile of rocks till I get the lens angle to where it doesn't cut my head off in the picture.
The instant on feature is awesome. Turn it on and it's ready to shoot a picture.
The fast shoot is the best thing ever. I can't tell you how many pictures I've missed with my other camera because it's focusing and processing whatever information. Push the button and it takes a picture, not "takes a picture 2 seconds from now."
WIth a high speed card you can take really great 640 x (whatever) movies. The movies are good quality and full motion. Not a camcorder replacement but fun for taking action movies at the drag races or whatever.
I haven't had problems with battery life. I think for the size and intended use it's fine. I turn the camera on, take a pic and turn it off. If you leave it on constantly, yeah, it's going to drain the battery. With the instant on and fast shooting, you can turn it on, take a pic and turn it off before most cameras can take a pic with it already on.
With the camera being so small, I don't mind taking my camera everywhere with me. It's nice because I'm taking pictures of a lot of things I never felt like lugging a camera around to take pictures of.
I've got Windows XP and there have been no problems (as stated earlier). Give your battery a full charge before you first start playing with it. I bought an extra battery but I don't think it's going to get much use. Don't forget to buy a high speed SD card. I got a 512m 32x speed and I think it will work for about anything I need. You could probably get away with a 256m no prob though.
Overall, I think it's an awesome little camera. If it had a little bit better zoom it would be perfect. It's an everyday camera. Fun to use.
It's not a replacement for my other camera though and I didn't buy it with those intentions. Keep that in mind and you will be extremely pleased.

I liked a lot of things about this camera, but had to return it for the following reasons. First, it has no lens cover, so it is not a good idea to carry it around in a pocket unless you also carry around something to clean the lens. Second, for some reason my very modern and up-to-date home computer (Windows XP) would not recognize the camera as a USB removable drive as the manual said it should, so I was unable to retrieve the pictures I'd taken at home. Finally, once I was able to download the pictures to a work computer, I did not see a marked improvement in picture quality over the pictures my old Canon S230 takes. Another negative is that charging the battery requires hooking the camera up to a 2-piece AC adaptor-like cable. Compared to the kind of charger that the Canon digicams come with (a small plastic unit that holds the battery and plugs right into the wall), this seemed like a step backwards. On the plus side, this camera is small, has lots of functionality I hadn't seen in a digicam before ("Portrait," "Sports" modes, can take multiple continuous pictures, movie modes, etc.), is very easy to use, and also the manual was extremely useful and easy to read.
