PowerShot SD770IS Highlights

3x optical zoom and Optical Image Stabilizer The PowerShot SD770 IS Digital ELPH’s 3x optical zoom is a clear winner when it comes to getting up close and personal. And Canon’s invaluable Optical Image Stabilizer reduces the blur of camera movement, even in tricky low light situations.

2.5-inch PureColor LCD II screen for bright, accurate color The PowerShot SD770 IS Digital ELPH gives you a large 2.5-inch LCD screen for excellent control when framing your shots. Canon’s PureColor LCD II offers more spectacular color, resolution and contrast even when viewed at an angle (compared to PureColor LCD). The screen is highly durable and easy to see in any light with a scratch-resistant, anti-reflective coating. It also features Night Display for easy viewing in low light -- a perfect feature for gathering friends and family around to see your images.

Motion Detection Technology automatically detects subject movement and optimizes exposure control Life doesn’t stand still for picture-taking. That’s why Canon included its advanced Motion Detection Technology in the PowerShot SD770 IS Digital ELPH. This sophisticated feature works in the background to instantly evaluate how fast your subject is moving. Then it automatically selects and sets the optimal exposure and ISO settings to keep everything looking sharp and clear. When you need higher ISOs for action-stopping shutter speeds, Motion Detection Technology provides it. But when no movement is detected, it allows lower ISOs for excellent color and detail. So whether you’re shooting a bride walking down the aisle, a ballet recital or even a child’s soccer game, you can relax and shoot with confidence knowing you’ve got the picture you intended.

Improved Face Detection Technology sets the focus, exposure, flash and white balance automatically Canon's powerful Face Detection Technology delivers even better results with the new SD770 IS Digital ELPH. The Face Detection Technology continues to recognize faces in a scene, and concentrate exposure (daylight or flash) and focus upon them. But the SD770 IS Digital ELPH adds more: Face Detection WB means the camera concentrates upon faces when calculating white balance for the best possible skin tones. Face Select and Track lets the SD770 IS Digital ELPH user highlight one face among several in a scene, and the camera concentrates on that person, even as they move around the scene. Face Detection Technology is a powerful contributing factor in Canon's new Motion Detection Technology.

DIGIC III Image Processor for superior image quality and improved functionality With DIGIC III, your images boast superior quality, the camera operates at top efficiency and battery life is enhanced. What’s more, DIGIC III enables Canon’s Face Detection Technology and Red-eye Correction to give you better, more true-to-life people shots. Simply press the Shutter Button halfway down, and the camera automatically pinpoints the faces in the scene and chooses the ideal focus point. The camera controls exposure settings and flash to keep every face looking bright and natural. Red-eye Correction can be handled in-camera, in two ways. The entirely new Red-eye Correction during shooting uses the Face Detection Technology to recognize and remove red-eye from flash images as they're taken, before the file is written to the memory card. It's also possible to correct red-eye during image playback, using simple settings in the SD770 IS Digital ELPH's menu.

iSAPS Technology is an entirely original scene-recognition technology developed for digital cameras by Canon. Using an internal database of thousands of different photos, iSAPS works with the fast DIGIC III Image Processor to improve focus speed and accuracy, as well as exposure and white balance.

Red-eye Correction provides three options for removing red-eye from subjects in flash pictures.
1) The new Red-eye Correction during shooting actually identifies and corrects red-eye in human subjects as pictures are taken.
2) The SD770 IS Digital ELPH can be set to automatically detect and correct red-eye during image playback.
3) The user can manually locate any red eyes in a scene during image playback on the LCD screen, and command the camera to remove them.

Print/Share Button for easy direct printing and downloading The PowerShot SD770 IS Digital ELPH's Print/Share button makes direct printing easier than ever. Simply connect the SD770 IS Digital ELPH to a Canon PIXMA photo printer or SELPHY compact photo printer or any PictBridge compatible photo printer, press the lighted Print/Share button and print! Also use the Print/Share button to transfer images to a computer (Windows and Macintosh).

Print your own ID photos in 28 different sizes or use the Movie Print function to output multiple stills from a recorded movie on a single sheet with a Canon SELPHY compact photo printer. 

Canon Ixus 85 IS /PowerShot SD770 IS Digital Camera Reviews

PhotographyPress has a review on the Ixus 85Is and writes "Taking the form factor of the IXUS 80 and the specs of the IXUS 90, the IXUS 85 offers 10 megapixels with a whole collection of clever features. But is it worth getting excited about? We get snapping to find out.

It is probably worth glancing over the reviews for the models that sandwich this new entry from Canon, because they do have an amazing number of similarities. In form, the IXUS 85 resembles the 80, although there have been minor design tweakings, and in our opinion, these go in the wrong direction. The subtle curvature of the 80’s front has been lost for a blander, more conformist appearance, not far off the 90; where the 80 was worth a second glance, the 85, perhaps, is not.

It does, however, carry the optical viewfinder, which some photographers will like, but again, it is very small. Making space for the viewfinder means losing some of the LCD screen size, coming in at 2.5in compared to the 90’s 3in. The screen is Canon’s PureColor LCD II, which we have praised in the past, and even on a bright day, the screen remains visible, which is where some models fail.

The remainder of the back of the camera carries the controls, which are the same as the 80, with minor changes barely worth a mention. The power, zoom and shutter button remain on the top, on the silver waist band. One thing we notice with the 85, that we didn’t notice with the 80, is that the batteryrattles; it may have been an oversight on our part, or might just be that it is more prominent in the 85.

The Face Detection works reasonably well, identifying the faces it can see, although doesn’t always stick with them. However, you can take superb shots without it knowing that you are capturing a face. The focus check option in review is a good double-up to ensure that you have actually got the right face in focus, although these checks do mean you need more time between shots – perhaps an option when perfect results are essential and you can take your time.

Picture quality, and this is probably where the real decision has to be made alongside the price, is very good and colours a nice and vivid. In bright conditions there is some blue tingeing around edges, marginally more than the 80, especially so on highlights. In suboptimal conditions Canon’s excellent DIGIC III processor, common to both cameras , re duces noise, but the downside is that some detail is lost.

Noise is still a problem with the higher ISO options but up to 400 is just about manageable. We did also notice some blurry corners, perhaps most evident in the river scene image, and barrel distortion which is a shame considering Canon’s good record with optics. "

Cnet  has this to say about the Canon Ixus 85 IS "

Design
Seemingly based on the design of the earlier IXUS 70, the 10-megapixel Canon Digital IXUS 85 IS is available in the same silver-on-silver or black-on-silver design, although the boxy edges have been replaced by curved corners and a slightly rounded face.

Despite being touted as the "smallest IXUS to date", the IXUS 85 IS is a mere 1.6mm slimmer than the IXUS 80 IS. It's also 0.6mm thicker than the IXUS 70, but to be fair, the IXUS 70 doesn't include image stabilisation so we have to allow for that.

It is however, still very compact at 54x86x20.4mm and weights a light 130 grams. And the whole IXUS range is pretty small anyway so a millimetre or two probably isn't going to sway your decision.

In terms of how the controls are laid out, the 85 IS is almost identical to the 8-megapixel 80 IS, though the controls on the back have been rearranged slightly, so to switch between shooting modes you now slide your thumb horizontally instead of vertically. All the controls are the same so we're not sure why Canon has switched it around, personally we find the old layout easy to navigate.

Features
The IXUS 85 IS offers the usual bells and whistles seen in Canon's snap shooter line; face detection, red-eye reduction, exposure compensation, a wealth of scene modes, the list goes on... It also features optical image stabilisation which is now standard on all Canon IXUS cameras.

In fact, the IXUS 85 IS's feature set is identical to that of the IXUS 90 IS, but at AU$429, it's AU$50 less. What you get for the extra cash is a larger LCD display — the 85 IS only has a 2.5-inch LCD compared to the 90's 3-inch screen, but like the 70 and 80 IS before it, the smaller screen allows room for an optical viewfinder, something we miss on most 3-inch LCD models.

Performance
The 85 IS fares well in terms of performance, clocking a very speedy one-second start-up time and approximately two frames per second in continuous shooting mode. Its single shot-to-shot time is an acceptable two seconds, making it not the fastest point-and-shoot but quite pleasing overall.

In true IXUS style, the 85 IS is easy to use and even beginners will learn the menu system quite quickly. Don't let the old stigma of "scene modes are for dummies" stop you from utilising the many scene modes as current compacts make good on many of the options, often taking a better photo than if you customise the settings yourself.

Image quality
Canon maintains its tradition of great image quality in the IXUS line, with colour reproduction standing out as particularly impressive. We noted good detail and sharpness in the centre of objects, with blur increasing towards edges along with slight purple fringing. The small sensor size has an impact on the IXUS 85 IS's image quality, with noise becoming apparent at ISO 200 — if you're fussy, we wouldn't go above ISO 800 although colours were still accurate and vivid even at the maximum of ISO 1600.

The narrow, 3x optical zoom lens is disappointing given its scope, displaying considerable barrel distortion at the widest-angle and less-evident distortion at the telephoto end.

The IXUS 85 IS is a slim, stylish camera which offers great image quality and a decent feature set but fails to stand out from the crowd. If you really need the 10-megapixel resolution, it's a good choice but we'd be willing to sacrifice a couple of megapixels in lieu of the colour choices and AU$50 price drop theIXUS 80 IS offers. And if you already own an IXUS 70 or 75, we don't see the need to upgrade just yet."
