Introduction: Announced on the 13th of July 2006, the Fujifilm FinePix F20 is a budget version of the popular Fujifilm FinePix F30. The F20 is a compact digital camera with a 6 megapixel sensor, a 3x optical zoom lens and a large 2.5" screen. The camera has the ability to take photos at upto ISO 2000, while most ordinary digital cameras stop at ISO 400. The 3x optical zoom lens is equivalent to 36 - 108mm on a 35mm camera. The Fujifilm FinePix F20 is available from around £95, this makes it excellent value for money for a compact 6 megapixel digital camera. The camera is enclosed in a sturdy body and is available in silver. The F20 can record video in 640 x 480 resolution at 30fps with sound. The body measures approx. 93.5(W) x 56.7(H) x 26.6(D) (without protruding parts), and weighs approx. 150g. excluding battery and memory card.

Casio have this to say about the camera:

"The EX-S770, a 7.2 megapixel digital camera with a smart look, features Casio’s Super Bright 2.8 inch wide-screen LCD but still retains the ultra-slim card size of its predecessors. Its impressive wide-screen display employs a 230,000 pixel LCD that clearly displays images and information down to the smallest detail, and boasts a maximum brightness of around 1100cd/m2; more than bright enough to see outdoors on a sunny day. Casio has also added many new functions to make the most of the EX-S770’s new wide screen."

You can find more information on their website.

Size comparison, compared to the Casio Exilim EX-S100 (the first "card" series to feature an optical zoom).

Compared to the 10 megapixel Casio Exilim EX-Z1050: The Z1050 is a 10 megapixel compact camera from Casio's "Zoom" series, and features a 2.6" screen, with ISO upto ?2000, and a 3x optical zoom lens, for full details, see the Casio Exilim EX-Z1050 review.

Apart from the styling there is little difference between these models - the lens, flash, focus-assist lamp, microphone, shutter release and battery / memory compartment are all located in the same place.

From the front: The F20 measures the same give or take a few millimeters, both cameras feature a compact metal body, with the F40fd featuring a more wedge like shape and a thinner body, and neither camera features much of a hand grip. The F20 features a mode selector on top that lets you choose between photo or video mode, while the F40fd features a mode dial on the back, and a zoom control on top of the camera surrounding the shutter release.

On the back: The screens appears similar, and the button layout is very similar, except the F20 features a zoom control on the back, and the F40fd features a mode dial instead. The modes are accessed through a menu on the F20. There is a face-detection button on the F40fd, while the F20 has an anti-blur mode button instead as it doesn't feature face-detection. (The simple solution to this is to point the camera at someone's face!)

Another view of the back shows the rubber-dotted grip below the zoom control on the F20 - and the thinner wedge like shape of the F40fd. The F40fd also features an infra-red port on the side.

Average box contents - The camera has a tiny amount of internal memory (6mb), and isn't supplied with a memory card. Purchase of an additional case is recommended to protect the metallic finish of the camera.

Battery usage: Battery life is rated at 200 shots according to CIPA standards - I was able to take over 220 shots before "battery empty" appeared. This is good but not as good as the Fujifilm FinePix F30 - with a battery life rated at 580 shots.

Camera Operation and Options: The play button turns the camera to review mode while the shutter release button returns it to photo mode. The play and record buttons can be used to switch the camera on. The video mode is started by using the red button on the back - you can take photos whilst recording a video. All other modes such as Audio, Scene modes etc are accessed using the Best Shot button at the back of the camera.

Photo mode/menus: The menu button brings up the menu screen as shown on the right below:

Photo modes	Menus

Screen / LCD display in photo mode: The screen has a high resolution of 230,400 pixels and updates smoothly - the colours appear accurate for reviewing photos. There is a live and review histogram available and the screen is clear and the text and menus are easy to read. The screen also has an automatic (and manual) brightness enhancer for taking photos where the screen is not clear, such as in bright sunlight. Optical Viewfinder: There is no optical viewfinder.

The camera has many options, things like resolution, flash, focusing mode, self-timer, anti-shake, ISO, white balance, exposure compensation, all quickly accessible through the SET button and the Panel Layout mode (you can choose whether you want this on or off, with it on it gives you quick access to the most commonly used features, with it off you have to go into the menu to change options). Flash options are one-touch buttons. One of the more interesting features is the continuous flash shooting mode - this lets you shoot three photos very quickly with flash.

Record Menu: Continuous, Self-Timer, Anti-Shake (digital), AF Area, AF assist light, Digital zoom, L/R Key (can be customised), Quick shutter, Audio snap, Grid, Review, Icon help, Memory.

Quality Menu: Size, Quality, Video Quality, EV shift, White Balance (including Manual), ISO, Metering, Filter, Sharpness, Saturation, Contrast, Flash Intensity, Flash assist.

Setup Menu: (shown on the right, above) The setup menu allows you to set: sounds (including the ability to mute all sounds apart from the "in-focus" sound, which is handy), startup image, image numbering to continuous (handy), time zones, switch on a timestamp (date, or date and time), adjust date, time, language, data view, sleep, auto power off, rec/play (use buttons to switch on camera?), USB, video out to NTSC / PAL, 4:3 or 16:9, reset and format.

Best Shot / Scene modes: (available by pressing the BS / Bestshot button) This has a large number of the usual scene modes. You'll also find video and audio recording in here, as well as the option to setup your own user created scene mode. The best shot video modes let you record a movie starting a few seconds before you've pressed the button! One scene mode that is unfortunately lacking from the S770 is the "Coupling" shot - this was always fun on the S100 combining the top part of someone's face with the bottom part of another person's face.

Data mode: ?

Playback:

Playback views (some of the views)	Playback Menu

Playback (Review) mode options: Scrolling through the photos is VERY quick - Casio say it can scroll through 100 photos in 10 seconds, should you ever want to view the photos this quick! The zoom is quick and works at up to 8x. Basic shot information is shown about the images, this can be switched to the view above with the display button. Playback menu: You can display a slideshow, edit movies, correct keystone, correct colour, rotate, resize, trim, dub audio, copy between the internal memory and vice versa as well as the usual printing options.

Picture Size / Quality: The camera takes the following size pictures, and the following number of pictures will fit in the provided memory:

As shown in the table above, higher quality images take a large amount of memory, and you can't fit very many photos in the 6mb of provided memory (simply treat it as a means of testing whether the camera works when you don't have a memory card), so a high capacity memory card is definitely recommended. There is a good choice regarding image size, quality and aspect ratios - with 16:9 and 3:2 ratio options available.

A large memory card is relatively cheap, and highly recommended, I would recommend a 512mb memory card, and preferably a 1gb memory card, as these are relatively affordable - the larger the memory card, the more photos you will be able to take. If you are likely to be away from a computer for a long time (such as when going on holiday) then the largest memory card you can afford would definitely be worth investing in. This camera takes only SD memory cards. Listed below are links to memory cards that will work with the Casio Exilim EX-S770:

Speed: The camera switches on and can take its first photo in 2.5 seconds. Focusing is fast at under half a second and continuous focus mode / high speed mode reduces this even more. The playback mode is also quick. The camera shutter response seems almost instant when pre-focused (around 0.1 second reponse) - and shot to shot time was quick at under 2.5 seconds (with review on without flash), with a delay of just under 2 seconds between shots in the normal continuous mode. The flash recharge time was equally quick - with a delay of around 3 seconds between shots. High speed continuous shooting is moderately quick, at roughly 2.5fps for upto 3 shots at the highest resolution. The cameras menus seemed responsive and zooming in and reviewing photos is all quick and easy to use. Moving around the different menu options is rapid.

Ease of use: The camera is very easy to use and has very easy to understand controls and buttons, for example, the main modes are video, photo or playback, simply switch the camera on and start taking photos. The controls on the back of the camera are easy to use and the mode switch and buttons are of an average size. The modes are easy to understand. The menus are responsive and easy to read. The camera is compact and has little in the way of a hand grip on the front, although there is a rubberised grip on the back which can assist in holding the camera steady. There are an extensive collection of scene modes for all types of different situations.

Ergonomics and Buttons: (Feel, placement, labels, etc) The buttons are fairly easy to use and are kept quite simple. The buttons are in a good position and easy to reach while composing shots. There seems to be a good amount of buttons for straight-forward digital camera use. The buttons feel okay and are an average size, the zoom control is fairly good and works well, although personally I prefer the zoom control to surround the shutter. The shutter release button is very good. The buttons are labelled well (with small symbols and little text). I thought the camera felt okay ergonomically, although there is little in the way of a handgrip. The compartments and covers seem well positioned and are easy to open, and the mode switch provides quick access to the main modes. The camera felt solid with a stylish metal body, however the battery cover opens quite easily and is made out of plastic.

Image Quality: Here are some real world sample photos taken in various settings, such as Inside, Outside, Macro, to demonstrate the quality of pictures taken and also show different features of the camera. Larger versions of these photos, plus more photos are available in the Fujifilm Finepix F20 Sample Photo Gallery!

Inside:

Heather and Flower (ISO200)	Flash photo (ISO100)

Inside: The camera has good colour - It took a good "Heather and Flower" photo - and red-eye in this photo and the other is low. The flash is quite bright and occassionally seems to over-expose the subject, especially when the camera decides to use ISO800 on AUTO ISO, when ISO100 or ISO200 would do the job much better - for example - I manually selected ISO200 for the "Heather and Flower" photo and the result was a much more saturated and pleasing photo. The camera did a good job at focusing most of the time even in low-light, thanks to the focus assist lamp. Colour is well saturated. The camera has a built in "Intelligent Flash" mode that will take two photos in quick sequense, one without flash (using a high ISO), and the other with flash (with a lower ISO).

ISO Noise Test: Noise: Noise is generally a bad thing - it removes detail, and gives a grainy effect over the image. With digital cameras noise can be a real problem as digital camera noise is often made out of blue, red or green dots. As the ISO setting increases, pictures tend to have more noise. Noise is most noticeable in dark areas of photos. The camera has an Automatic mode for ISO levels (ranging from ISO 100 - ISO2000), and manual ISO settings (ISO: 100, 200, 400, 800, 1600).

Below you'll find the noise test image, plus actual pixel crops from the image taken at different ISO settings, compared with the 7 megapixel Canon Powershot A550 and 8 megapixel Fujifilm FinePix F40fd.

ISO Noise Test Photos - Flash is off. Canon Powershot A550 on the left, Fujifilm FinePix F20 in the middle, Fujifilm FinePix F40fd on the right. Any tonal difference is due to automatic white balance or metering differences.

Thanks to Fujifilm's unique Super CCD sensor, the Fujifilm FinePix F20 and F40fd has low noise upto ISO800. ISO1600 produces acceptable results, however, detail is lacking and ISO2000 is probably best left unused unless absolutely necessary (ISO2000 is only available in one of the natural light / anti-blur modes). Compared with the Canon, noise is much lower than the Canon Powershot A550, and you can see that the F20 and F40fd retains more detail even when the ISO setting is increased. The Fujifilm cameras manage to produce low noise images right up to ISO800 with very good detail. If you take a lot of indoor pictures, then the Fuji F20 or F40fd makes an excellent choice. Nb. The picture stabilisation / anti-blur mode simply uses a higher ISO setting to avoid image blur, and is not a true image stabilisation system such as an anti-shake sensor, or optical image stabilisation.

Outside:

Liverpool shops (ISO100)	Flowers (ISO100)

Outside: The camera has quite rich, saturated colours, with good contrast. There was very good detail, and the camera took a number of very pleasing images outside, but areas with huge variation in brightness do show signs of 'bleeding' and purple fringes. In general 'normal' quality jpeg artefacts are not easily seen, however areas with strong contrasts benefit from use of the highest quality setting.

Zoom: This camera has a 3x optical zoom lens and a built in 6.2x digital zoom - in the case of this camera the digital zoom basically takes a smaller area of the photo and enlarges it using software blurring the image so that it is not pixellated. Generally it's best to avoid using digital zoom as it degrades the quality of the image and, often, better results can be obtained by using a photo package such as Adobe Photoshop. I've included examples below to show what the zoom is capable of.

Wide-angle	3x Optical Telephoto Zoom	Full Optical and Digital Zoom

Exposure: The photos of the clock tower are exposed well with detail in the dark areas as well as the lighter areas - exposure in other photos was generally good. Purple fringing is noticable in the wide angle but very little is seen in the 3x optical zoom photo. Vignetting was not noticed. It can be useful to under expose images with bright backgrounds (eg; sky) with use of exposure compensation.

Lens noise and zoom: The lens is relatively quiet in operation. The camera gives good control over how you frame your subject with around 9 steps between wide and telephoto zoom (although it skips quickly across the range).

Other Image Quality issues: Purple fringing was occasionally seen particularly in areas with high contrast.

Macro: the macro mode allows you to be roughly 5-6cm away from from the subject, this is with the lens zoomed out. For best results are achieved use manual white balance and a more diffuse light source. Note that if you get very close to the object you want to photograph, the location of the flash and the lens will create a shadow in the bottom right of the image, and it is best to try and avoid using the flash.

Timex Watch Macro	Actual Pixels (ISO100)

The custom white balance helps get better colours in the macro mode when using an un-natural light source - the closest the camera can get to the subject is about average at around 5-6cm. Noise seems low in this photo and detail and colour is very good.

Video mode: The camera features a high resolution VGA 640 x 480 video mode at 30 fps with sound. Video quality was good however this will use memory quickly - a 10 second video recorded at 640 x 480 took 11 megabytes. Both optical and digital zoom are unavailable while recording a video.

Conclusion

Summary: The Fujifim F20 is a very impressive compact 6 megapixel digital camera with a 3x optical zoom lens and a large 2.5" display. The camera offers almost identical performance to the Fujifilm FinePix F30, however, at a price that puts it head to head with other budget digital cameras. The Fujifilm FinePIx F20, with the impressive Fujifilm Super CCD sensor, successfully outperforms it's competition, and many other cameras costing three times the price with regards to low light / low noise performance. The camera is one of very few to include usable high ISO modes of ISO 1600 and ISO 2000, and noticably less noise than the competition at all ISO settings upto ISO 800 (The only other cameras offering similar performance are either Digital SLRs or other Fujifilm FinePix digital cameras!). It has excellent responsiveness and is designed to be able to take great photos in almost every situation. For the price, I don't think you can get a better camera!

I have been recommending the Fujifilm FinePix F series to family and friends ever since the F10, and they have all been happy with their purchase - If you want a budget digital camera then the FinePix F20 makes an excellent choice, being much more responsive than the majority of other budget cameras - If you want manual controls and a high ISO range then the FinePix F30 or F31fd make an excellent choice, with ISO upto 3200 - and if you want a high resolution point and shoot then the F40fd makes an excellent choice, with the highest resolution of the series. Whichever one you decide upon, they all offer excellent low light, low noise performance, great image quality, and very good responsiveness, especially with the High Speed mode activated.
