Casio EX-FH25 Review

August 9, 2010 | Gavin Stoker |

Image Quality

All of the sample images in this Review were taken using the 10 megapixel Fine JPEG setting, which gives an average image size of around 5Mb.

As anyone would expect when shooting hand held with a super zoom that despite all its DSLR stylings has the same size sensor as a regular point and shoot snapshot, the images captured aren't going to be able to hold a candle to a DSLR with a larger chip and dedicated equivalent lens.

That's to say the Casio's images are slightly soft for the most part, particularly so when shooting handheld at extreme telephoto setting even when conditions - bright blue skies - are seemingly ideal in terms of light. Still if it's a choice between being able to get the shot you intended and not, then you'll put up with such shortcomings.

Though exposures are even for the most part, in common with most compacts highlight detail is too easily lost. As our white wall test shots reveal, there's a bit of a fisheye effect at maximum 26mm-equivalent wideangle, though on busier scenes this is much less noticeable, and it has to be said that edge-to-edge sharpness is fairly well maintained. Though we've found Casio images a tad warm in the past, and did here find white balance a tad inconsistent from shot to shot when left on auto settings, for the most part colours are naturalistically rendered. The FH25 is one of the worst offenders in its bridge camera class however for visible pixel fringing between areas of high contrast.

In terms of ISO performance, it's only really when you get to ISO3200 that quality noticeably deteriorates, the results resembling a fuzzy analogue TV signal. Still, at this top setting quality is no better or worse than lesser compacts can manage at ISO1600.


There are 6 ISO settings available on the Casio EX-FH25. 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)

ISO 3200 (100% Crop)

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 a little soft at the default sharpening setting. You can change the in-camera sharpening level if you don't like the default look.

Chromatic Aberrations

The Casio EX-FH25 handled chromatic aberrations fairly well during the review. There's some obvious purple fringing between areas of high contrast, as shown in the examples below.

The Casio EX-FH25 offers a SuperMacro setting that allows you to focus on a subject that is 1cm 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.

The flash settings on the Casio EX-FH25 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 (26mm)

Flash On - Wide Angle (26mm)

ISO 64 ISO 64

Flash Off - Telephoto (520mm)

Flash On - Telephoto (520mm)

ISO 64 ISO 64

And here are a couple of portrait shots. As you can see, neither the Forced On setting or the Red Eye Reduction options caused any amount of red-eye.

The Casio EX-FH25's maximum shutter speed is 30 seconds, which is great news if you're seriously interested in night photography. The shot below was taken using a shutter speed of 4 seconds at ISO 100. I've included a 100% crop of the image to show what the quality is like.
