The Camera: a visual tour: (Photos of the camera taken with the Panasonic Lumix FZ30)
Size Comparison: Compared to a Pentax 35mm film camera - a medium/compact sized 35mm film camera.
Specifications / Features:
Average / poor box contents - 8mb of provided memory is something you rarely see, even on 3 megapixel cameras! You will need to buy a larger memory card and a case (as with almost all digital cameras). Rechargeable batteries are also highly recommended, and it's a shame they didn't print a larger manual.
Battery usage: Up to 170 pictures with the supplied Alkaline batteries according to CIPA / CASIO testing. This is very good for alkaline batteries, and Oxyride or high-powered Ni-Mh rechargeable batteries should provide much better battery life. I managed around 2,800 (yes, two thousand and eight hundred) continuous VGA shots with 2350mAh Ni-Mh batteries, with the flash off!
Menu Options / Modes: The camera mode is selected using the back dial.
Photo mode/menu: The menu button brings up the menu screen as shown on the right below:
Screen / LCD display in photo mode: (shown on the left) The screen resolution with 84,960 pixels is below average, although text is still clear and the colour appears quite accurate on the screen. The camera has a live histogram that also shows you the green, blue and red channel. The text and menus are easy to read. Optical Viewfinder: There is a small optical viewfinder that may be useful in bright sunlight.
Photo menu options: Continuous, Self-Timer, Auto focus area, Anti Shake (enables ISO800, and ISO1600, and will try to use a higher ISO speed instead of using flash), L/R key customisation, Quick shutter, Audio snap, Grid, Digital zoom, Review, Memory.
Photo Quality Options: Size, Quality, Video quality, EV shift, White Balance (includes shade, and custom white balance as well as the usual), ISO, Metering, Filter (Off, Black and White, Sepia, Red, Green, Blue, Yellow, Pink, Purple), Sharpness, Saturation, Contrast, Flash intensity, Flash Assist (lightens darker areas of images).
Easy Photo Mode menu options: Flash, Self-Timer, Image Size. Limited options, with the choices explained with a short paragraph when selected.
Scenes: Each scene has a short explanation underneath. The scenes are: Portrait, Scenery, Portrait with Scenery, Children, Sports, Candlelight portrait, Party, Pet, Flower, Natural Green, Autumn Leaves, Soft Flowing Water, Splashing Water, Sundown, Night scene, Night scene portrait, Fireworks, Food, Text, Collection, Backlight, Anti-shake, High sensitivity, Pastel, Illustration, Cross, Monochrome, Retro, Twilight, ID Photo, Business cards and documents, White board etc, Register user scene. The last one allows you to customise / setup as many of your own scene modes as you want.
Setup menu options: Sounds (Startup, Half-shutter, Shutter, Operation, Play), Battery type, Startup, File number, World time, Adjust Date/Time, Date style, Language, Sleep, Auto power off, Rec/Play, USB, Video out, Format, Reset.
Playback (Review) mode/menu: The menu button brings up the playback menu screen as shown on the right, below:
Playback mode: Scrolling through the photos is very quick. The zoom is quick, and allows you to zoom up to 8x.
Playback menu options: Slideshow, Motion print, Movie editing, White balance (adjustable after taking the photo!), Brightness, Favourites, DPOF, Protect, Rotation, Resize, Trimming, Dubbing, Copy.
Picture Size / Quality: The camera takes the following size pictures, and the following number of images will fit on the 8mb memory provided with the camera:
As shown in the table above, you can fit a very small number of images on the 8mb provided - a large memory card is needed, using the internal memory is simply not an option - unless you want to take VGA photos on the Economy setting! The memory should only be used to test the camera in my opinion. There is a good choice of image sizes and aspect ratios, and a good choice regarding image compression.
A large memory card is relatively cheap, and highly recommended, I would recommend at a bare minimum a 256mb memory card, and preferably a 512mb memory card, or larger, especially considering the relatively low prices - the larger the memory card, the more photos you will be able to take. If you are likely to go on holiday then the largest memory card you can afford would definitely be worth investing in, as you don't always know when you will next be at a computer. Listed below are links to memory cards that will work with the Casio Exilim EX-Z120:

Speed: The camera is fairly quick to switch on and take photos, being ready in just under two seconds. Focusing seemed fairly quick even in low-light taking roughly 0.5 - 1 second to focus depending on lighting and the subjects distance from the camera. The camera shutter response seemed very quick (less than 0.1 seconds) when pre-focused. Shot to shot time was quite sluggish, with a delay of 3 - 4 seconds between shot when using flash, as you had to wait for the flash to recharge before you could take the next photo - without flash shot to shot time was better, with a delay of 1 to 2 seconds between shots. The flash recharge time was a bit slow - taking between 1 and 2 seconds. The cameras menu's seemed very quick and responsive. Continuous shooting is average, it is unlimited at roughly 1fps (without flash). The playback mode is very quick with pictures appearing instantly as you scroll through them. In use, it felt like a quick and responsive camera, thanks to the quick focusing and very quick shutter response.
Ease of use: The camera is very easy to use, especially in the EASY mode, or one of the scene modes, even though the camera has a lot of options. The camera is easy to use in any mode, even in manual mode, it's easy to work out how to set the shutter and aperture without having to refer to the manual. The controls on the back of the camera are very straight forward with clear play / record buttons (a favourite of mine). The menus are very responsive and easy to read and navigate. They are also easy to use, and the options are big enough and easy enough to see clearly. The modes are easy to access, quick and simple, mainly thanks to the clear and easy to use dial and buttons on the camera.
Ergonomics and Buttons: (Feel, placement, labels, etc) The buttons are very easy to use, and they are in a good position. There seem to be the right amount of buttons - and dials allowing easy access to the most commonly used functions and features. The buttons feel good, and only the power button is on the small side - the others are quite "normal" sized, and not as small as other cameras, although not especially large either. The shutter release is quite good. The buttons are labelled fairly well. I thought the camera felt good ergonomically, although there is little in the way of a hand grip. I like the zoom control that surrounds the shutter release. The camera, with it's metal body, feels like a solid, robust and well built camera.
Image Quality: Here are some sample photos taken in various settings, such as Inside, Noise, Outside, Zoom, 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 Casio Exilim EX-Z120 Sample Photo Gallery!
Inside: The camera has good colour - It took a good "Heather and Flower" photo - there is very little red-eye in the photo. It has a fairly decent flash (despite its small size), and copes well with group photos, although red-eye was more noticeable. The camera did a good job at focusing even in low-light. Images were slightly soft, and seemed better with sharpness turned up in camera. * Paler than usual due to pale foundation.
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, and manual ISO settings (ISO: 80, 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. * ISO 800 and ISO1600 are available with "Anti-shake" mode turned on or by using the "Anti-shake" or "Natural Light" scene modes.
Noise is visible in photos taken at ISO50 and ISO100, at these low ISOs you would normally expect (or hope) there to be no noise, however the noise isn't too bad - as it appears more like film noise, rather than blue, red and green spots. Noise at ISO200 and ISO400 is quite noticeable, and at ISO800 or ISO1600 noise is very high and details is much softer. ISO800 and ISO1600 may be appealing if you only want to print or view small images and if you prefer natural light rather than flash.
These increased ISO settings (ISO800 and ISO1600) are part of Casio's "Anti-shake DSP" and are an occasionally useful feature that a lot of manufacturers (Panasonic, Olympus etc) seem to be adding - but they aren't as good as real hardware anti-shake, such as Panasonic's "Mega Optical Image Stabilisation", or Konica Minolta's Anti-shake CCD sensor, as they often dramatically reduce image quality. The only manufacturer who seems to have provided very good high ISO performance in a compact digital camera is Fujifilm, with the Fuji FinePix F10/F11.
Outside, the camera had very good colour, with good contrast and saturation. There was good detail although images did seem slightly soft. There seemed to be good dynamic range. Noise seemed quite low, especially on sunny days. I didn't notice jpeg artefacts in the images. * Manually under exposed with -0.7 exposure compensation.
Zoom: The camera has a 3x optical zoom lens, and a 4x digital zoom - I've included examples below to show what the zoom range of the camera is. Using the digital zoom degrades image quality and is best avoided.
Exposure / Metering on the photos of the clock tower seems good, with the dark areas of the photo not too dark, and the bright areas of the photo still visible.
Lens noise and zoom: The lens is quite quiet, slightly quieter than average. The shutter is quiet. There are roughly 6 steps between wide and telephoto giving you good control on how you frame your subject.
Other Image Quality issues: Purple fringing seemed very low.
Macro: You can use the flash in macro mode, although this has a tendency to wash out the picture when the subject is too close. The camera can be roughly as close as 10cm away from the subject from the front of the lens in wide setting, when set to macro mode.
The macro mode is average - colour and detail is very good, although images could do with being slightly sharper, and it would be nice if you could get closer to the subject.
Movie: The movie mode on this camera is very good with VGA resolution at 30fps, with sound. The camera also has a 320x240 video mode with sound. The camera did well even in low light. Videos are recorded as .AVI files.
Summary: The Casio Exilim EX-Z120 is a compact, metal bodied digital camera that provides very good 7 megapixel images. The camera provides a good 2" screen, excellent battery life, a good video mode, and an average macro mode. The camera provides a mode for every type of digital camera user, from the very beginner, to the advanced expert and the digital camera is very easy to use in all modes. The camera doesn't appear to cut back on features, yet still manages to provide excellent value for money as one of the cheapest 7 megapixel, 3x optical zoom digital cameras available. The Casio Exilim EX-Z120 is definitely recommended!
