Editorial Review:Product Description:Introducing the world's smallest optical zoom digital camera– with 3.2 megapixel resolution and 2.8x optical zoom! You can take it with you anywhere– it's about the size of a deck of cards and weighs less than four ounces (without the rechargeable battery and memory card). The secret to its tiny size is the world's first high-refractive ceramic lens, which can be produced in a much slimmer size than glass.

- 3.2 megapixels
- 2.8x optical zoom
- Ultra-compact design

The S100 is as remarkable for its speed as for its size. The shutter-response-time of 0.01 seconds means you can capture the most fleeting of moments. And the quick start-up takes you from 'off' to ready-to-shoot in as little as 1.4 seconds. Slip this tiny marvel in your pocket and you're always ready to take your best shot.

My a quick review of this greal little jewel
I have a big and bulky Nikon Coolpix 8700 camera but I needed something handy for my sightseeing trip to Japan. After looking over about a dozen smaller cameras, I picked this one. I haven't regretted it my decision!
First, the looks of it: It is the most awesome hi-tech looking camera I've ever seen! And it feels sturdy (all metal case). Not cheap like some plastic body cameras. It feels "expensive"!
I've had people compliment me on the camera and ask about it.
Next: it is so tiny! And I really didn't need 8MP for snapshots. The 3MP of this camera has is quite enough for snapshots. The camera has an internal memory but you'll really need a memory card (I bought 512Mb card). I also bought a leather carrying case which can be strapped to a belt. That is how I was carrying it most of the time. Camera is also small enough to be stuffed into a shirt pocket.
The LCD screen is very big and easy to see in all conditions except in direct sunlight shining from the back.
Also, the tiny LiIon battery has an incredible life. I just put it in the charging cradle every night and took pictures all day. Never ran out of power.
While on the cradle, it can be hooked up to your computer via a USB bus. I don't even use any of the software which came with the camera. My PC sees the camera as a USB storage device. I just manually copy the images wherever I want and then edit them using my favorite Image Editing software,
It has zillion of features (most of which I'll probably never use). But I did play around with it to see what can be done.
With a little tripod and some setting changes, you can also take some great night shots (using the timer release of course). When used in this mode, the shutter's open time is longer than normal and it processes the picture differently, making it quite a bit less grainy than when taking night shots using standard shooting modes.
I also love the quick power up, quick focus and no shutter lag!
And the way all the controls are laid out is very intuitive and easy to learn.
There are many other features and other items already covered by other reviewers - so I won't go into them.
Things I wish the camera did better:
LCD display in low light conditions is quite dark (it doesn't "brighten" the display like some other cameras do).
Since it is so tiny, it has a very weak flash. It doesn't do well in dimly lit rooms if the subjects are not right close to the camera. But, this is not surprising considering the size of this camera (no room for a big capacitor) and the flash tube itself is miniscule. Also, part of the problem here is that the largest aperture of the tiny lens is F4. Pictures taken in the dark can also be a bit grainy. But in daylight this camera works great.
The lack of full printed manual is also a negative. Nice full manual is included on the CD (in pdf format) but you only get a skimpy printed manual which doesn't cover any of those more advanced features. I already know the basics. And while some people can deal with manuals viewed on the computer screen, I really need a paper manual. So, I printed it and had it bound. It helped me quite a bit to gain the insight into all the features.
So far I've taken hundreds of pictures (and some movies) with it and I am extremely happy with this tiny CASIO! No mechanical problems either. As people in New England say: Wick'd awesome!
And CASIO has been making digital cameras for a very long time. In the mid 90s I've bought a QV-100 (which I still have, and it still works). That was a first digital camera made which used LCD screen and had a tiltable lens! It had a mind-blowing VGA (640x480) resolution! :-) And it downloaded pictures via a serial port. Now, CASIO is still making great, leading-edge products.

micro magic
My first digital camera and i'm rather pleased with myself. After reading amazon usa reviews of the ex100 i picked up a "bundle" that included the ex case and a 512 meg memory card. The camera itself is tiny, very well built and simplicity itself to operate. It will suit "snappers" rather than diehard camera junkies, such is the limitation of 3.2 megapixels. Overall at its current discounted price its a real no brainer of a bargain.

just back from trip WOW
I took this on a 2 week trip to Italy.....I took 1158 pic's and several movies, I was NOT disappointed in any way...the movie feature worked well, the avi's had a very good picture with no scramble pixilation issues, sound was very good as well... for it's size, a great feature..the pics are fantastic, I took several sepia and black and white shots as well.......
My friend had a Casio 5.0 mega and the differences, once we had several photos delivered from Kodak were basically, so difficult to see that I am glad I paid less and bought this one...he was disappointed he didn't get better quality for HIS money...why pay way more for what amounts to almost unseen incremental advantage?
On another note, I use photoshop extensively and cropped and zoomed many shots, unles you are trying to zoom into something very far away, you will still have a great shot, I took many architecural shots around Monuments in Rome and zoomed many of them, from 100 feet or so you are fine with this camera...you can still pull the details that interest you...
The one draw back mentioned by others, which is a draw back for all LCD view cameras is; in bright light it may difficult to see through the viewer, but it takes almost direct light coming from behind to create this hazard, but as I said they all suffer that shortcoming.
Other blurbs...its very small but easily manipulated..it fit into a zippered shirt pocket and its almost like you're not carrying a thing....the menu is intuitive....the battery re-charges within and hour......you can bring the cradle which comes with the camera, (which is compact as well) buy a $10.00 voltage converter and recharge in countries with different voltage outlets...
I had zero issues with it...great camera especially for this price....I won't have to upgrade for quite a while.... :-)

An Amazing Camera
Wow! Casio really did a great job in designing this camera. It's very small; when I got it out of the box I was a bit shocked at its size. It feels solid in my hand. The on/off button is nice and discreet; a cinch to turn on, but it wont turn on inside your pocket, thats for sure. The rechargable battery is just icing on the cake; it fully charges in less than two hours!
This is a camera for a person who wants great quality pictures, but doesn't want to spend all their money on a 5 megapixel, 2.5 inch screen monster. I turn the size to 1 megapixel size anyway so the pictures don't take up a ton of space on my hard drive. 3.2 megapixels is more than enough. Highly recommended for a first time camera buyer.
