External Controls

Shutter Button: Resting in the center of the Zoom lever, this button sets
focus and exposure when halfway pressed, and fires the shutter when fully pressed.
Zoom Lever: Surrounding the Shutter button on the top panel, this lever
controls the optical and digital zoom while in Record mode.
In Playback mode, the wide side displays a nine-image index display of all
images on the memory card, and accesses a "Jump" function that lets
you scroll through index display screens quickly. Alternatively, the telephoto
position enlarges the currently displayed image as much as 10x, so that you
can check on fine details.

Mode Dial: Also on the camera's top panel, this large, notched dial is used
to select the camera's shooting modes. Canon divides these functions into three
categories: Auto, Image Zone, and Creative Zone. The options are as follows:
Auto:
The camera controls everything about the exposure, except for Flash and Macro
modes, image size and quality settings.
- Creative Zone
Program
AE (P): Places the camera in control of shutter speed and lens aperture,
while you maintain control over everything else (i.e., white balance,
ISO, metering, exposure compensation, flash, etc.).
Shutter-Speed
Priority AE (Tv): Allows you to control the shutter speed settings
from 1/2,000 to 15 seconds, while the camera controls the aperture. All
other exposure settings are available.
Aperture
Priority AE (Av): Allows you to set the lens aperture from f/2.8 to
f/8.0, while the camera controls the shutter speed. The maximum aperture
depends on the zoom setting, ranging from f/2.8 at the wide angle end
to f/4.8 at the telephoto position. In this mode, you maintain control
over all other exposure variables.
Manual
(M): Provides complete control over all exposure settings, including
shutter speed and lens aperture.
- Image Zone
Portrait:
Uses a large aperture setting to blur the background while keeping the
primary subject in sharp focus.
Landscape:
Employs a small aperture setting to keep both the background and foreground
in focus. (May use a slower shutter speed, so a tripod is recommended.)
Night
Scene: Uses slower shutter speeds and flash to even out nighttime
exposures. The slow shutter speed allows more ambient light to be recorded
in the low-light areas, while the flash freezes the subject. The Red-Eye
Reduction mode can be used with this exposure mode to eliminate Red-Eye
in night portraits.
Fast
Shutter: Uses fast shutter speeds to stop action and maintain sharp
focus on moving subjects.
Slow
Shutter: Uses slow shutter speeds to blur fast-moving subjects.
Special Scene: Choose from Foliage, Snow, Beach, Fireworks, Underwater,
and Indoor modes.
Stitch-Assist:
Allows you to record a series of images, either horizontally, or vertically,
to be "stitched" together into one panorama on a computer.
Movie: Records as long as three minutes of moving images with sound, at approximately 15 frames per second (except in 640 x 480 mode, which is only 10fps).

Power Button: To the left of the Mode dial, this button turns the
camera on or off.

Mode Switch: Adjacent to the top right corner of the LCD monitor
on the rear panel, this switch selects between Record and Playback modes.

Five-Button Function Pad: These five buttons are arranged in a
disk pattern on the rear panel, right of the LCD monitor. They serve as the
left, right, up, and down arrow keys to navigate through settings menus, and
the center button is the Set button, better-placed in our opinion. In Record
mode, the left and right buttons adjust available exposure settings, as well
as manual focus, when enabled. The top button controls flash mode, while the
bottom button accesses Macro and Manual Focus modes.
In Playback mode, the left and right buttons scroll through captured images.
When an image has been enlarged, all four arrows pan within the view.
Set Button: Now part of the 5-way navigator right of the LCD monitor,
this button confirms menu selections. It also switches between available exposure
adjustments in Manual mode.

Print/Share button: Glows blue when enabled for printing to a PictBridge
printer or Windows computer for uploading images.

Function / Erase Button: On the lower right corner of the LCD monitor, this
button displays the following Function menu while in Record mode:

- Exposure Compensation: Increases or decreases the exposure
from -2 to +2 exposure equivalents (EV) in one-third-step increments. Not
available in Manual mode, since the user controls the exposure variables directly
there.
- Flash Output: (Manual mode only, takes the place of the Exposure Compensation option): Adjusts the overall flash intensity from Low to Full, in Manual mode only. In Manual mode, the flash fires only a single pulse, handy when you want to use the A85 with conventional "slave" triggers for external flash units.
- White Balance: Controls the color balance of images. Options
are Auto, Daylight, Cloudy, Tungsten, Fluorescent, Fluorescent H, and Custom
(manual setting).
- Drive Mode: Accesses Continuous Shooting and the two Self-Timer
modes (a 2 or 10 second delay).
- ISO Speed: Sets the camera's sensitivity to Auto (except
in Manual), or to 50, 100, 200, or 400 ISO equivalents.
- Photo Effect: Enables Vivid Color, Neutral Color, Low Sharpening,
Sepia, or Black-and-White picture effects.
- Light Metering System: Sets the metering mode to Evaluative,
Center-Weighted, or Spot.
- Resolution: Specifies the image resolution and quality settings. Still image resolutions are 2,272 x 1,704; 1,600 x 1,200; 1,024 x 768; and 640 x 480 pixels. The new Postcard mode defaults to 1,600 x 1,200 for fine 4x6 printing, with the option of date printing on the photo. Quality options (activated by pressing the Set button) are Superfine, Fine, and Normal. Movie resolutions are 640 x 480, 320 x 240, and 160 x 120 pixels.
In Playback mode, this button displays the single-image erase menu.

Display Button: Below the LCD, this button controls the information and
image display modes in Record and Playback modes. Playback includes a histogram
view.

Menu Button: Right of the LCD and above the Function button, this button
calls up the settings menu in Record and Playback modes. It also dismisses the
menu screen and backs out of menu selections.

Battery Compartment Latch: Nestled in the center of the battery compartment
door on the bottom of the camera, this sliding switch unlocks the door, so that
it can slide forward and open.

Lens Ring Release Button: Tucked under the lens on the camera's front panel,
this button releases the lens ring. Once unlocked, the lens ring can then be
turned and removed to accommodate accessory lens kits.
Camera Modes and Menus
Record Mode: Marked on the Mode switch with the red camera
icon, this mode sets up the camera for capturing still and moving images. The
following exposure modes are available:
Manual
(M): Provides complete control over all exposure settings, including shutter
speed and lens aperture.
Shutter-Speed
Priority AE (Tv): Allows you to control the shutter speed settings from
1/2,000 to 15 seconds, while the camera controls the aperture. All other exposure
settings are available.
Aperture
Priority AE (Av): Allows you to set the lens aperture from f/2.8 to f/8.0
(depending on the zoom setting), while the camera controls the shutter speed.
In this mode, you maintain control over all other exposure variables.
Program
AE (P): Places the camera in control of shutter speed and lens aperture,
while you maintain control over everything else (i.e., white balance, ISO,
metering, exposure compensation, flash, etc.).
Auto:
The camera controls everything about the exposure, except for Flash and Macro
modes, and image size and quality settings.
Portrait:
Uses a large aperture setting to blur the background and keep the primary
subject in sharp focus.
Landscape:
Employs a small aperture setting to keep both the background and foreground
in focus.
Night
Scene: Uses slower shutter speeds and flash to even out nighttime exposures.
The slow shutter speed allows more ambient light to be recorded in the low-light
areas, while the flash fully exposes the subject.
Fast
Shutter: Uses fast shutter speeds to stop action and maintain sharp focus
on moving subjects.
Slow
Shutter: Uses slow shutter speeds to blur fast-moving subjects.
Special
Scene: Choose from Foliage, Snow, Beach, Fireworks, Underwater, and Indoor

Recommended Software: Rescue your Photos!
Just as important as an extra memory card is a tool to rescue your images when one of your cards fails at some point in the future. I get a lot of email from readers who've lost photos due to a corrupted memory card. Memory card corruption can happen with any card type and any camera manufacturer, nobody's immune. A surprising number of "lost" images can be recovered with an inexpensive, easy to use piece of software though. Given the amount of email I've gotten on the topic, I now include this paragraph in all my digicam reviews. The program you need is called PhotoRescue, by DataRescue SA. Read our review of it if you'd like, but download the program now, so you'll have it. It doesn't cost a penny until you need it, and even then it's only $29, with a money back guarantee. So download PhotoRescue for Windows or PhotoRescue for Mac while you're thinking of it. (While you're at it, download the PDF manual and quickstart guide as well.) Stash the file in a safe place and it'll be there when you need it. Trust me, needing this is not a matter of if, but when... PhotoRescue is about the best and easiest tool for recovering digital photos I've seen. (Disclosure: IR gets a small commission from sales of the product, but I'd highly recommend the program even if we didn't.) OK, now back to our regularly scheduled review...

- Color: Very pleasing color. Somewhat high saturation, some hue errors, but apparently in a way that results in very appealing images. Like many consumer digicams, the A85's color is fairly bright-looking. - But that's because most consumers like bright, snappy-looking photos. The A85's color balance was generally quite accurate, and its Incandescent and Manual white balance options both did a very good job with the difficult household incandescent lighting of my "Indoor Portrait" shot. The one oddity I found in its color rendition was obvious only in the analytical results from Imatest. - The camera tends to shift cyan colors towards the blue range somewhat. As noted, I wasn't really aware of this visually, other than to note that the A85 tends to render shades of off-blue a little more "richly" than in real life. I suspect that the main impact of this tendency would be more appealing sky colors.
- Exposure: Generally accurate exposure. Somewhat high contrast, but good ability to hold onto highlight detail. The A85's exposure system was generally pretty accurate, requiring the same or slightly less exposure compensation on challenging shots than most cameras I test do. Like most consumer digicams, its tone curve is a little contrasty, but despite this, the A85 does a much better than average job of holding on to detail in strong highlights. A very good performance overall..
- Resolution/Sharpness: High resolution, 1,150 lines of "strong detail." The A85 performed pretty well on the "laboratory" resolution test chart. It started showing artifacts in the test patterns at resolutions as low as 800 lines per picture height, in both horizontal and vertical directions. I found "strong detail" out to at least 1,100 lines vertically, 1,200 lines horizontally. "Extinction" of the target patterns occurred around 1,500 lines. Using its "MTF 50" criteria, Imatest reported average resolution of 943 line widths/picture height, or 1113 LW/PH when normalized to a standard 1-pixel sharpening. Overall, this is just a little off from the performance of the best 4-megapixel cameras, but is still fairly good.
- Image Noise: Slightly higher than average image noise for its 4-megapixel class, but very little loss of subtle detail to anti-noise processing. The A85 has a tendency to produced slightly high image noise on average, with some noise visible even at ISO 50. The grain pattern is fine and tight though, which makes it less objectionable than it would be otherwise. I don't personally care for the results at ISO 400, but visually, they look better than those of most consumer cameras at that level (despite the fact that the numeric noise figures are a fair bit higher than average), and I suspect that a lot of people would find them acceptable for limited usage.
- Closeups: A small macro area with excellent detail, but the flash has trouble up close. The A85 performed well in the macro category, capturing a minimum area of 2.53 x 1.90 inches (64 x 48 millimeters). Resolution was very high, and detail was excellent in the brooch, coins, and dollar bill. Details were very sharp throughout most of the frame, though all four corners were soft. (Softness in the corners of the frame is unfortunately a very common failing among consumer digicams in Macro mode.) Color and exposure looked good as well. The A85's flash had trouble throttling down for the macro area, and overexposed the shot. - Plan on using external lighting for your closest shots with the A85.
- Night Shots: Good low-light performance, with relatively low image noise. Autofocus works down to a bit darker than one foot-candle. (Slightly darker than typical city street lighting at night.) The A85 produced clear, bright, usable images down to the 1/16 foot-candle (0.67 lux) limit of my test at the 200 and 400 ISO settings. At ISO 100, images were bright as low as 1/8 foot-candle (1.3 lux), and at ISO 50, images were bright as low as 1/4 foot-candle (2.7 lux). Color was good with the Auto white balance, though just slightly pink at the lower light levels. The A85 handled image noise well in the low light tests, producing low noise levels at the 50 and 100 ISO settings, and only a moderate level at ISO 200. Even at ISO 400, noise was high, but not overpowering, at least not compared to what I'm accustomed to seeing from consumer digicams at that level. While the A85 could successfully shoot at very low light levels though, its autofocus system worked only down to about 0.7 foot-candles, just a little darker than typical city night scenes.
- Viewfinder Accuracy: Excellent accuracy from the LCD monitor, but a very tight optical viewfinder. The A85's optical viewfinder was very tight, showing only about 77 percent frame accuracy at both wide angle and telephoto zoom settings. The LCD monitor proved much more accurate, at about 100 percent. Given that I like LCD monitors to be as close to 100 percent accuracy as possible, the A85's LCD monitor is just about perfect in this respect, but the camera really needs a more accurate optical viewfinder.
- Optical Distortion: Average barrel distortion, higher than average pincushion, very low chromatic aberration and good sharpness across the frame. Optical distortion on the A85 was about average at the wide-angle end, where I measured approximately 0.8 percent barrel distortion. The telephoto end fared only slightly better, as I measured 0.6 percent pincushion distortion there. Chromatic aberration was quite low, showing three or four pixels of very light coloration on either side of the target lines. (This distortion is visible as a very slight colored fringe around the objects at the edges of the field of view on the resolution target.) The A85's images also tended to show good sharpness in the corners, a relative rarity with typical digicam optics. Overall, a good quality lens.
- Shutter Lag and Cycle Time: Shutter lag and cycle times on the fast side of average. Overall, the A85 is a little faster than average in most aspects of its performance. Startup and shutdown are a bit quicker than most digicams with telescoping lenses manage, shutter lag is just on the fast side of average in full-autofocus mode, and very fast when the camera is "prefocused" by half-pressing and holding down the shutter button prior to the shot itself. Cycle times are good if not astounding, and the camera's four-shot buffer memory should be plenty for most consumers. All in all, not blazing speed, but a solid performer all the same.
- Battery Life: Excellent battery life. With worst-case runtime of 229 minutes in capture mode with the rear panel LCD illuminated (based on "standard" 1600 mAh NiMH cells), and more than 16 hours with the LCD turned off, the A85's battery life is much better than average. I still recommend buying at least two sets of high-capacity NiMH AA cells and a good charger, but the A85 does a lot better than most cameras on the market in the battery-life department. (See my Battery Shootout page for test results from a variety of batteries, and read my review of the Maha C-204W to see why it's my new favorite AA-cell charger.)

As I mentioned at the outset, Canon's PowerShot A70 topped the charts in Canon's
sales last year, outstripping all other camera models. - And for good reason:
The A70 offered a rich set of features and excellent image quality at
an attractive price. This year, the PowerShot A85 appears poised to follow in
the A70's footsteps. Relative to last year's model, the A85 offers a better,
nine-point autofocus system, a bigger monitor, a slightly more accurate optical
viewfinder, and faster overall performance. The A85's image sharpness is just
a tad off that of the best 4-megapixel cameras on the market, but is more than
good enough to make sharp-looking 8x10 prints. Its color is very appealing,
even though its handling of blues appears to be tweaked a little from what would
be absolutely accurate - The nature of the blue tweak appears to be such that
the A85 will render better-looking sky colors, something most users would probably
prefer to an absolutely faithful portrayal. Overall, Canon has taken an almost
perfect combination of features, image quality and price, included a number
of key features from its S-series digicams delivered the
combination at a very attractive price, making a premier camera for the mid-level
consumer market that's also a bargain. If you're looking for a great "all
around" digicam, the A85 certainly deserves your serious consideration.
- It's an easy "Dave's
Pick," as one of the better models on the market.
