The strong chromatic aberration (color fringing left and bottom up to 8 pixels at 9 megapixels and 520mmKB) limited the usable zoom range to approximately 26-300mmKB for good image quality.
Fascinating are the high-speed and Vowegaufnahme properties and the operating concept of this camera. Anti-Shake is so good that I could take with focal length 41mmKB, ISO 100, 9MP, even at 0.4s (!) Exposure time freehand blur-free images (but also because of my quiet trip). This is also necessary because with each step up the ISO images are considerably blurred by the noise reduction.
I praise cameras with 4 AA batteries (Mignon), which I can procure cheaper and with more capacity in any amount.
At a glance:
++ High-speed continuous shooting up to 40fps and high-speed videos possible to 1000fps
++ Anticipation recordings in temporary storage from half pressing the shutter button
long pressed more shots from the press of the shutter
Number of pictures before / after by pressing the shutter fixable, 40
Image sequence 1-40fps
Video anticipation recording last 5s (maximum) prior to pressing the shutter button
++ Unique operating concept with the following controls:
* Mode dial with only the really important modes are spontaneously selected:
Video / high-speed video / still image / High Speed CS / Lightning series
* Rocker switch with the situational adjustments are feasible:
ISO / White Balance / Flash style / Belichtungsmessungsart / Entfernungsmessungsart / resolution
* Direct keys:
* ON / OFF
* EVF / LCD switch screen / viewfinder
* MENU Here About done all basic settings
* DISP switch the display mode
* Zoom lever and shutter
* Macro button to switch between AF / Macro / Super Macro / MF
* Up to lightning flash Unfolding
* BS to select from the "Best Shot" recording modes
* AEL activated preset AE and / or AF Lock
* Record button to switch from playback to recording
* Playback button to switch from recording to playback
+ Display of the current focal length
+ 4 AA batteries
Blurring + freehand recording 0.4s (!) At focal length 41mmKB without possible

- Unnecessary With Video forced choice between zoom or recording.
- White balance is not separated for image and video
- Noise reduction can not be disabled
- No standard USB connector
- Viewfinder much fainter and smaller (even with "+2") than other bridge cameras
- Chromatic Aberration of 8 pixels at 520mmKB
- Significantly slurred recordings by noise suppression over ISO 100
(Even at ISO 100 slightly faded as my old Konika Minolta Dimage Z3)

1: 1-image excerpts from the original three cameras with the same motives:
* From 9MP the Casio Exilim EX-FH20 with focal length 41mmKB for ISO 100-800
* From 4MP the 4 year old Konika Minolta Dimage Z3 with 57mmKB for ISO 50-400
* From 12MP Pentax X90 with the focal length 26mmKB for ISO 100-800
* Chromatic aberration of 8 pixels of the Casio Exilim EX-FH20 with 520mmKB
Basically, with a 9 megapixel sensor (4,5MP for green and depending 2,25MP for blue and red) can strictly speaking only produce a 2.25 megapixel tri-color image of the highest quality. For higher resolution color interpolation (ccd-sensor.de/html/1_-_chip_ccd.html) is necessary. When pseudo resolution of 9 megapixels, the system-related blur is clearly visible.
I use those cameras with a resolution of 5 megapixels at medium quality level. As a little side effect resulting from the Casio Exilim EX-FH20 a possible intelligent zoom to 27x. More resolution, or the highest level of quality would be pure waste of space without real benefit, since the sensor no longer will bear because of color interpolation. Only in 2-megapixel resolution would make sense the highest level of quality "Optimal". This is so fundamental for digital cameras from all manufacturers.
Who needs a higher resolution, has to resort to SLR cameras with much larger sensors. For example, supplies the Pentax Kx significantly sharper images and also has 4 AA batteries (Mignon). But SLR cameras are also due to the system much more expensive, harder, bigger and much louder, which in turn particularly bother me.
Unfortunately all camera manufacturers indulge in a telephone, pixel and ISO-mania that is at the expense of image quality and storage requirements, it is still valid: 6mpixel.org/?page_id=94
With 5 megapixels and ISO 100, the Casio would have been to 300mmKB roughly equivalent to my Konika, poorer viewfinder but would be accepted in exchange for high-speed, anticipation recordings and the better operating concept the strong chromatic aberration over 300mmKB (the Konika Minolta Dimage Z3 has none at all) was the reason to return the Casio.
