Image Quality

All of the sample images in this Review were taken using the 9 megapixel Fine JPEG setting, which gives an average image size of around 4Mb.

The Casio EX-FS10 produces images of good quality. The biggest issue is noise and loss of detail at relatively slow ISO speeds. The 1/2.3 inch, 9 megapixel sensor recorded noise-free images at ISO 100, but there's already some noise and slight softening of detail at ISO 200. ISO 400 shows a little more noise, loss of fine detail and significant colour desaturation, and ISO 800 and 1600 are even worse, with obvious loss of fine detail and even more noise. The Casio EX-FS10 handled chromatic aberrations very well, with limited purple fringing effects appearing only in high contrast situations and generally at the edges of the frame. The built-in flash worked well indoors, with no red-eye and good overall exposure. The night photograph was poor, with the maximum shutter speed of 4 seconds not being long enough for most after-dark shots, resulting in under-exposure. Anti-shake is a feature that sets this camera apart from its competitors and one that works very well when hand-holding the camera in low-light conditions or when using the telephoto end of the zoom range. Macro performance is below par, allowing you to focus as close as 10cms away from the subject. The images were soft straight out of the Casio EX-FS10 at the default sharpening setting and ideally require some further sharpening in an application like Adobe Photoshop, or you can change the in-camera setting.

Noise

There are 5 ISO settings available on the Casio EX-FS10. Here are some 100% crops which show the noise levels for each ISO setting.

ISO 100 (100% Crop)	ISO 200 (100% Crop)
ISO 400 (100% Crop)	ISO 800 (100% Crop)
ISO 1600 (100% Crop)

Sharpening

Here are two 100% Crops which have been Saved as Web - Quality 50 in Photoshop. The right-hand image has had some sharpening applied in Photoshop. The out-of-the camera images are soft at the default sharpening setting and benefit from some further sharpening in a program like Adobe Photoshop. You can also change the in-camera sharpening level to suit your tastes.

Original (100% Crop)	Sharpened (100% Crop)

File Quality

The Casio EX-FS10 has 3 different image quality settings available, with Fine being the highest quality option. Here are some 100% crops which show the quality of the various options, with the file size shown in brackets.

9M Fine (3.67Mb) (100% Crop)	9M Normal (2.03Mb) (100% Crop)
9M Economy (1.39Mb) (100% Crop)

Chromatic Aberrations

The Casio EX-FS10 handled chromatic aberrations excellently during the review, with just a small amount of purple fringing present around the edges of objects in certain high-contrast situations, as shown in the example below.

Example 1 (100% Crop)

Macro

The Casio EX-FS10 offers a Macro setting that allows you to focus on a subject that is 10cms away from the camera when the lens is set to wide-angle. The first image shows how close you can get to the subject (in this case a compact flash card). The second image is a 100% crop.

Flash

The flash settings on the Casio EX-FS10 are Auto, Flash Off, Flash On, and Red Eye Reduction. These shots of a white coloured wall were taken at a distance of 1.5m.

Flash Off - Wide Angle (38mm)	Flash On - Wide Angle (38mm)
Flash Off - Telephoto (114mm)	Flash On - Telephoto (114mm)

And here are some portrait shots. As you can see, neither the Flash On or the Red-eye reduction settings caused any amount of red-eye.

Flash On	Flash On (100% Crop)
Red Eye Reduction	Red Eye Reduction (100% Crop)

Night

The Casio EX-FS10's maximum shutter speed is 4 seconds in the Night Scene Best Shot mode, which is disappointing news if you're seriously interested in night photography, as it doesn't allow you to capture enough light in most situations. The shot below was taken using a shutter speed of 2 seconds at ISO 100. I've included a 100% crop of the image to show what the quality is like.

Anti Shake

The Casio EX-FS10 has an electronic anti-shake mechanism, which allows you to take sharp photos at slower shutter speeds than other digital cameras. To test this, I took 2 handheld shots of the same subject with the same settings. The first shot was taken with anti shake turned off, the second with it turned on. Here are some 100% crops of the images to show the results. As you can see, with anti shake turned on, the images are much sharper than with anti shake turned off. This feature really does seem to make a difference and could mean capturing a successful, sharp shot or missing the opportunity altogether. Be warned though that the system increases the ISO speed to minimize subject movement, with the User Guide stating that "Shooting with Anti Shake can cause an image to appear somewhat coarser than normal and can cause slight deterioation if image resolution".

Shutter Speed / Focal Length	Anti Shake Off (100% Crop)	Anti Shake On (100% Crop)
1/20th / 38mm
1/6th / 114mm

30 FPS Mode

The Casio EX-FS10 can shoot an incredible 30 frames in just 1 second (the resolution automatically drops to 6 megapixels). After the sequence of shots has been captured, the camera takes around 10 seconds to process them, during which no further pictures can be taken. This montage demonstrates what 30 frames per second can actually capture.

High Speed Video

In addition to the highest quality HD 720p, 1280x720 pixels at 30fps video mode (example here), the Casio EX-FS10 also offers 3 different high-speed video modes - 480x360 pixels at 210fps, 224x168 pixels at 420fps, and 224x64 pixels at 1000fps. Here are some examples for each setting:

View the 210fps Movie (33.4Mb)

View the 420fps Movie (32.7Mb)

View the 1000fps Movie (17.6Mb)

Conclusion

The Casio EX-FS10 shares most of the key features of its bigger, more expensive brother, the EX-FC100 model, but it ultimately falls short in a couple of key areas. The battery life is much worse, recording just 125 shots and a couple of movies before needing to be recharged, so you'll need to budget for a spare. While the 3x folded optic lens allows the camera to be incredibly slim, it's also slow at either end of the rather limited zoom range - again the FC100 is a lot better in this regard. The position of the lens tight in the corner of the camera body also makes it easy for your left forefinger to inadvertently appear in your photos.

On a more positive note, the ability to shoot 30 images in one second at the touch of a button is amazing for any camera, DSLR or compact, and if you can't choose the best shot, then the EX-FS10 can do that for you too. The only downsides are the reduction in resolution to 6 megapixels, which applies to all of this camera's high-speed still image functions, and despite that, the fact that memory cards quickly fill up if you regularly use the burst mode. On the video side, the EX-FS10 can record both 720p HD and super slow-motion movies, although both modes are somewhat hampered by huge file sizes, poor or no sound, the inability to optically zoom, and in the case of slow-motion, drastically reduced resolutions. Still, having all of this functionality in such a compact and well-built camera puts the Casio EX-FS10 at the head of the action pack.

As with the FC100, the FS10's image quality doesn't quite match the feature list, suffering from less than stellar images in low-light due to obvious noise appearing at ISO 200 and faster. Most of this camera's recent main rivals also suffer from this problem, but they typically offer 12 or more megapixels, rather than the 9 megapixels of the EX-FS10. The fastest shutter speed of 4 seconds limits what you can do after dark, although the innovative High-Speed Night Scene mode partly makes up for this by allowing you to successfully hand-hold the camera in relatively low-light conditions. Anti-shake is only of the electronic software-based kind, which adversely affects image quality, and the 10cm macro mode is also disappointing on a 2009 camera.

$349.99 / £299.99 is a high price to pay for what is essentially a point and shoot compact with merely good image quality, so you really need to ask yourself if you will make full use of all those high-speed shooting options. If the answer is yes, then the Casio EX-FS10 is clearly one of the best cameras around for capturing all of the action. We'd still opt for the EX-FC100 though, which offers better battery life, a bigger LCD screen, mechanical image stabilisation and a closer macro mode, unless you really need the ultra-portable dimensions of the FS10...
