SX100 IS - Digital Camera Review |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Canon have this to
say about the camera: "Get in on the action
with a 10x zoom lens. PowerShot SX100 IS keeps your subject in focus with
Face Detection and optical Image Stabilizer. Clear, simple controls are
easy and flexible for the whole family. Face Detection Technology ensures
superb people shots by automatically setting optimum focus, exposure and
flash. Face Select and Track lets you choose your primary subject from
up to 35 identified faces. Red-Eye Correction in playback keeps eyes looking
natural." You can find more information on their website. The Camera: a visual tour: (Photos of the camera taken with the Nikon D40x)
Size Comparison: Compared to a Pentax PC-550 35mm film camera - a medium/compact sized 35mm film camera.
Specifications / Features:
Box Contents:
Average box contents - a larger memory card would be nice, as would a neck strap. A decent case, a large memory card and some high power rechargable AA batteries are recommended. Battery usage: Battery life is rated at 400 shots with 2500 mAh Ni-Mh rechargable batteries according to CIPA standards. I was able to take around 310 shots before the batteries went flat when I was using 2500mah batteries, and around 80 shots when using Alkaline batteries. Camera
Operation and Options: The camera mode is selected using
the top dial. This allows the choice of: Auto, P, Tv (shutter priority),
Av (aperture-priority), M (Manual), Video, Panoramic Stitch Assist, Scene
(Indoor, Foliage, Snow, Beach, Fireworks, Aquarium, Night scene), Kids
and Pets, Night snapshot, Landscape, and Portrait. Photo mode/menus:
Screen / LCD display in photo mode: (shown above) The screen resolution with 172,000 pixels is average, but the screen is clear and colours are good. In the display is - shutter speed, aperture setting, ISO, focus area, shots remaining, surrounded by camera settings. You can quickly change ISO, Focus, Flash, Shooting mode, and Exposure using the buttons on the back. Optical Viewfinder: There is no optical viewfinder. Function Menu: Pressing the Function button brings up an overlay of some of the most commonly used options, such as: White balance, My Colours (Vivid, Custom (Contrast, Sharpness, Saturation), etc), Flash +/-, Exposure mode, Image Quality, Image Size. Photo / Record Menu: AF Frame (Center, Face Detect), AF Frame Size (Normal, Small), Digital Zoom (Off, Standard, 1.6x, 2.0x), Slow Synchro, Red-eye, Safety FE, Self-timer (delay, shots), Auto ISO shift (Off, On, Print button), MF-Point Zoom, Safety MF, AF mode (Single, Continuous), AF Assist beam, Review, Review info (Off, detailed, focus check), Display overview (Off, Grid lines, 3:2 Guide, Both), IS mode (Off, Continuous, Shoot only, Panning), Set print button (can be set to: None, WB, Custom WB, Digital Tele-converter, Display overview, Display off). Face Detection Focus Features: I felt the need to detail this, because there seem to be a huge number of new Face Detection focus features on this camera, some of them may actually be useful!
Because I don't have this many friends, I've used a photo of people from the internet. 16 faces detected out of 17 isn't bad - on another try I was able to get the camera to detect all 17 faces! Wow, that's progress for you, how did we ever manage to take photos without face detection focus? ;) Personally, I see little real benefit in Face Detection focus, however being able to check the focus of people after you've taken the photo is a clever idea, and the playback face checker view mode could be a useful feature for quickly checking that all your subjects are in focus, especially if you're lucky enough to have so many friends, or if you regularly take group photos! Playback:
Playback (Review) mode options: Scrolling through the photos is very quick. The zoom is quick. There are numerous views available, zooming out will get you a 9 thumb view. Pressing the display button you get a normal view, with basic information, one screen of more detailed information (EXIF information including highlight over-exposure), and a face detection zoom view. When zooming in you can set an area to zoom into, and then scroll through the photos with that area magnified by using the scroll wheel.
Playback menu: Auto play, red-eye correction, resize, sound memo, protect, rotate, erase all, transfer order, transition. Print menu: Print, Select images and quantity, select all images, clear all selections, print settings. Setup Menu: Mute, Volume, Start up image, LCD brightness, Power saving, Date / Time, Format, File numbering, Create folder, Auto rotate, Distance units, Lens retract, Language, Video system, Print method, Reset all. Picture Size / Quality: The camera takes the following size pictures, and the following number of pictures will fit onto the 16mb of provided memory,
As shown in the table above, higher quality images take a large amount of memory, so a high capacity memory card is definitely recommended, unless you're prepared to sacrifice image size or use higher compression options to fit more pictures in memory. There is a very good choice of image sizes and compression options. A large memory card is relatively cheap, and highly recommended, I would recommend at a bare minimum a 1gb memory card, if you intend to take JPEG images, and preferably a 2gb memory card, or larger. 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. You can use SD or SDHC memory cards - I tend to use Sandisk Ultra II Plus USB SD memory cards as these let you plug the memory card straight into a USB socket making it easy to transfer images onto any computer, they are available as 1GB SD cards, or 2GB SD cards.

(with USB reader) Speed: The camera is fairly quick to switch on and take photos, from off, to taking a photo in 2.3 seconds. Focusing seemed fairly quick, except in very low light when the flash-assist is used - this takes a little longer to focus depending on the subject. The playback mode is also very quick. The camera shutter response seemed instant when pre-focused responding in 0.1 seconds or less - and shot to shot time was fairly quick, with a delay of around 2.0 seconds between shots without flash (with review off shot to shot time was slightly quicker). The flash recharge time was very slow only allowing a shot to be taken every 6 seconds, although it was available in the continuous shooting mode, with a more reasonable shot to shot time of around 2 seconds. The cameras menus seemed quick. Continuous shooting is average, at roughly 1.3fps for multiple shots at the highest resolution, dependant on card technology used. Ease of use: The camera is easy to use, especially in the AUTO mode and has a number of scene modes that helps get good shots. The controls on the back of the camera are quite straightforward. The menus are responsive and are also easy to use, and the options are big enough and easy enough to see clearly, although built in help would have been nice. The modes are fairly easy to access, mainly thanks to the large screen, and a lot of the options can be accessed using the buttons on the back. It's easy to see when photos are in focus, and the image stabilisation means that more of your shots will be sharp. Ergonomics and Buttons: (Feel, placement, labels, etc) The layout of the buttons and controls are good, with the most commonly used options reachable with your right hand. The zoom control and shutter release is good. The scrolling wheel has multiple functions and in play mode is used to compare magnified sections of one image with the previous or next, making it simple to decide which shot is the one with least camera shake (much like the scroll wheel that's been common on DSLR for several years). I thought the camera felt very good ergonomically, with a good sized hand grip, however there is no rubber grip at the front or back of the camera. The camera feels like a solid, robust and well built camera that is easy to hold despite the small size, and fits easily into pockets.
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 Canon Powershot SX100 IS Sample Photo Gallery! Inside:
Inside: The camera has very good colour - It took a good "Heather and Flower" photo - there is no red-eye in the photo. It has a very good flash, and copes well with group photos, however there was some red-eye in some group photos, but for the most part red-eye was quite low. On AUTO ISO, the ISO setting was kept quite low in these photos (ISO200), however noise was noticable, and better results may be possible by using a lower ISO setting, especially if the subject is close to the camera. The camera did a good job at focusing even in low-light. There is an focus assist lamp to help focus. Colour is richly saturated. Photos taken on "Vivid" setting - this produces high saturation, and good contrast levels, on the normal setting images were less colourful and seemed to lack contrast. This can all be customised to your tastes. 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 80 - ISO1600), and manual ISO settings (ISO: 80, 100, 200, 400, 800, 1600). Below you'll find the noise test image, plus actual pixel crops, viewable at 100%, from the image taken at different ISO settings, compared with the 8 megapixel Fujifilm FinePix F40fd and 8 megapixel Panasonic Lumix DMC-FZ18.
ISO Noise Test Photos - Flash is off. Fujifilm FinePix F40fd on the left, Canon Powershot SX100 in the middle, Panasonic Lumix DMC-FZ18 on the right. Any tonal difference is due to white balance or lighting / metering differences.
Noise results: The Canon Powershot SX100 IS has relatively low noise upto ISO200. ISO400 produces acceptable results, and ISO800 and higher is probably best left unused unless absolutely necessary. Compared with the other two cameras, noise does appear much more noticable, however, when compared to the Panasonix FZ18, you can see that the SX100 retains more detail even when the ISO setting is increased. However neither the Canon or the Panasonic perform as well as the Fujifilm, which manages to produce low noise images right up to ISO800 with very good detail. Image Stabilisation: The camera features optical image stabilisation... Outside:
Outside: The camera has quite rich, saturated colours. There was very good detail, and the camera took a number of very pleasing images outside, with good contrast, but there was often chromatic aberations and purple fringing, especially in areas of high contrast on sunny days. 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 lens provides a 10x optical zoom starting at 36mm equivalent which is great for 'normal' everyday photography, zooming to 360mm allowing photos of distant objects. I've included examples below to show what the zoom is capable of. An example of digital zoom can be seen in the photo gallery. Digital Zoom basically takes a crop of the centre of the frame and enlarges the image, degrading image quality, and is therefore best avoided.
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 very good. Purple fringing was noticed in some of these photos. Vignetting was not noticed in these photos but was occassionally noticed when using the full 10x optical zoom. It can be useful to under expose images with bright backgrounds (eg; sky) with use of exposure compensation, as some of the clouds in these photos are slightly over-exposed. Lens noise and zoom: The lens makes some noise, and gives you roughly 21 steps between wide and telephoto - this gives good controls over how you frame your subject. Other Image Quality issues: Purple fringing / Chromatic aberration was occasionally seen particularly in areas with high contrast (for example tree branches against a bright sky). It was slightly higher than average compared to most other compacts, and is something that you should probably be aware of, especially if you take a lot of outdoors shots. Macro Lens Performance:
The camera can take maco photos where the subject is only 1cm away from the lens! Colour and detail is very good, and there appears to be low noise at ISO100 and below, however some is visible in this ISO200 shot. Setting the white balance manually helps achieve better results. The camera can also take macro photos when zoomed in slightly, and will display the minimum focus distance on screen, which is helpful. More examples can be seen in the gallery. Video mode: The camera features a good video mode - it records VGA videos at 30fps with sound as AVI files. Compared to other digital cameras the Canon can't fit very long videos on the memory card, as it doesn't use very high compression, such as MPEG4. The video mode doesn't let you use the optical zoom whilst recording. Conclusion
