Image Quality
All of the sample images in this Review were captured using the 10M Fine JPEG image size option producing a file that
is around 5Mb in size.
Noise
The Casio EX-Z200 has 6
ISO settings which you can select in the majority of shooting modes. There is virtually no discernible noise at
the slowest settings of ISO 50 and 100, but smoothing and slight
loss of detail is apparent at ISO 200. At ISO 400 image quality has deterioated quite
a lot, and ISO 800 suffers from even more noise. The fastest setting of ISO 1600 should only be used as a last resort,
if at all. Here are some 100% crops which show the noise
levels for each
ISO
setting.
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 at the default setting are a little bit soft and benefit
from some further sharpening in a program like Adobe Photoshop.
Alternatively you can change the in-camera sharpening level
if you don't like the default results.
File Quality
The Casio EX-Z200 has 3 different image quality settings available,
with Fine being the highest quality JPEG option. Here are
some 100% crops which show the quality of the various options,
with
the file size shown in brackets.
Chromatic Aberrations
The Casio EX-Z200 dealt
fairly well with chromatic aberrations during the review, with
some obvious but limited purple fringing effects present around the edges of
objects in high-contrast situations. Here are some 100%
crops which show the typical chromatic aberrations that you
can expect:
Macro
The Casio EX-Z200 offers
a Flower scene mode that allows you to focus on a subject that
is 15cms away from the camera. The first image shows how close
you can get to the subject in Macro mode (in this case a
compact flash card). The second image is a 100% crop.
Flash
The flash settings on the Casio EX-Z200 are Auto, Flash Off, Flash On, Soft Flash, and Red Eye Reduction. These shots of a white coloured
wall were taken at a distance of 1.5m.

And here are some portrait shots.
As you can see, neither the Auto and Red-Eye Reduction
options caused any amount of red-eye.

Night Shot
The Casio EX-Z200 maximum
shutter speed is 4 seconds in the Night scene mode, which is
not very news if you're interested in night photography.
The shot below was taken using a shutter speed of 4 seconds,
aperture of f/2.6 at ISO 50. I've included a 100% crop of
the image to show what the quality is like.

Anti Shake
The Casio EX-Z200 has a
CCD-shift 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
ISO speed set to 100. 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 a lot 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.

Overall Image Quality
The Casio EX-Z200 produced
images of below average quality during the review period.
The 10 megapixel images were soft straight out of the camera
at the default sharpening setting and ideally require some
further sharpening in an application like Adobe Photoshop,
or you can increase the in-camera sharpening level. The Casio EX-Z200 handled chromatic aberrations fairly well,
with obvious but limited purple fringing effects appearing in high
contrast
situations. Macro performance is well below average, allowing you to
focus as close as 15 cms away from the subject. The built-in
flash worked well indoors, with no discernible red-eye and good exposure. The night photograph was OK, with the maximum
shutter speed
of 4 seconds limiting the kind of shots that you can take after dark. 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. The Casio EX-Z200 produces noise-free images at ISO 50 and
100, but ISO 200 and 400 show noise and smoothing of detail. ISO
800 exhibits a lot of noise, and the fastest
setting of 1600 should only be used in an emergency.
