Pros
Many manual controls
Wide-screen mode
Cons
Low battery life
Lacks exposure bracketing
Bottom Line
Low-priced model offers many manual controls, a generous 4X zoom, and a wide-screen mode. But battery life was unimpressive.
Canon PowerShot A540
Powershot A540 Digital Camera (6.0MP, 2816x2112, 4x Opt, SD/MMC) Review, by Richard Baguley July 26, 2006
The $280 (as of 6/15/06) PowerShot A540 offers a lot of features for those who want to manually set controls such as shutter speed for full creative control. It's one of the few cameras in this class that offers full manual control as well as the usual fully automatic modes. There's also a good selection of scene modes: 13 in all, including three that are very easily accessed on the mode dial (you access the rest through the on-screen menu by setting the mode dial to SCN).
The camera body is pretty small (at just over 3.5 inches wide and 2.5 inches tall), but it is somewhat thicke: At 1.7 inches deep, it's a bit bulky to fit comfortably into most pockets. The 4X zoom lens (which is longer than the 3X lenses we typically see on point-and-shoot cameras) telescopes out of the front of the body. The camera feels comfortable in the hand, and you can change the shooting mode one-handed because the mode dial falls under the thumb. The manual control is also well executed: You can set the shutter speed and aperture with one hand.
The image quality of the 6-megapixel images is about average (though the A540's scores match those from many more-expensive models): Colors were accurate (though they lacked the vividness of the Olympus FE-120) and the camera accurately judged exposure (it also offers auto exposure bracketing). The images were a little soft, however: Some fine details were lost in the blurriness, and the edges of objects sometimes lacked definition. And like a growing number of point-and-shoots offering higher ISO settings than past models, the A540 is lets you can crank up the ISO setting to 800; previous models peaked at ISO 400. However, the A540's images got rather noisy; at anything above ISO 200, the noise pattern was noticeable and distracting, and the colors become flat and dull.
One interesting option is the wide-screen mode: This shoots an image with a resolution of 2816 by 1584 pixels that has a 1.8-to-1 aspect ratio that is close to the typical HDTV wide-screen image. The camera itself can't output an HDTV image, though: the only output is composite video.
The A540's battery life of 191 shots, from the two disposable AA batteries, was a little on the low side. You can also use optional AA NiMH rechargeable batteries, but these cannot be recharged inside the camera. Canon sells a kit with four rechargeable batteries and a charger for $60--well worth the investment. Canon also offers a range of accessories, including wide-angle and telephoto lenses that attach around the existing lens (a plastic ring around the lens base unscrews to allow each to attach).

Duration of ownership: 10 Months
Strengths: Fantasticly sharp photos, very easy to use.
Weaknesses: Very, Very, Very bad battery life.
Overall: Buy a Nikon L11 camera. I gave up trying to carry my Canon A540 around to take impromptu photos, the battery would go dead within a few days. I bought a Nikon L11, put the alkaline batteries that came with the camera in, and it has been going strong for over 3 weeks. The Nikon also has a setting for what kind of battery you are using - alkaline, NiMH recharable ot lithium.

Strengths: Manual Features, Various modes, quality photos, Flash, Micro mode and all other features.
Weaknesses: High refresh time if flash is used, not soft switching between play and display mode, not slim in look.
Overall: I am fully satisfied with this product because I have been looking for a camera in my budget having all manual features since a year. Finally I got to this one and tried. Really awesome! Have compared results with other SLRs and digital cameras and felt better enough. No product is complete and this is not an exceptions but worth to buy it as a first camera if having photography as one of your hobbies. ...

Strengths: Reasonably priced. Compact camera size with a generous display size. Uses off-the-shelf AA batteries. Excellent battery life (I'll explain later). Video quality exceeds that of my digital camcorder. Photos taken exhibit good color and contrast and are well exposed.
Weaknesses: Canon has adopted a single door design which is used to gain access to both the memory card and the two AA batteries. Flash recycle times can be a little long.
Overall: This is my third and forth Canon camera purchase for personal use. I purchased one for myself and one for my son who travels a lot with his high school band. I have previously owned a Canon A40 and an A85, both of which still work fine, but I wanted to upgrade. There have been over 2000 photos and numerous video clips taken with these cameras, including a Thanksgiving parade in Chicago and a couple of Disney parades. This feat was accomplished with one 4-pack of lithium AA batteries for each camera, since my NMiH charger died soon after I bought the cameras. How much you use your camera to review photos and videos will shorten batteryl life on all cameras. DO NOT USE ALKALINE BATTERIES IN ANY DIGITAL CAMERA. You will be disappointed unless you only take a few photos a month. Lithium or NMiH are the ONLY way to go.

Strengths: easy to use, good picture quality
Weaknesses: shot-to-shot wait time too long, short battery life
Overall: I've had this camera for a while. In general, I like it partly because it's my first digital camera and partly because it's easy to use for an amateur like me. However, I'm convinced that either there's something wrong with the design or it's just the one I bought was defective. I don't know if this has happened to other people who have this model, but the lens cover of mine was broken about 10 months after I bought it. I have always taken care of this camera well and never let it fall or bump into anything. It just happened all of a sudden--the lens cover only opened up half way or not at all when I turned the camera on, and it didn't close completely when I turned the camera off. Now I end up having to open or close it using my fingers every time I use the camera. It's very incovenient. Since I paid over $200 for it, I was hesitant to spend more to get it fixed when the problem started. In fact, there are a lot of newer, cheaper digital cameras out there now. I might as well buy a brand new one by a different maker.

Strengths: Fast Autofocus, almost no shutter lag, optical viewfinder included, small but still easy to hold when shooting, good color accuracy, can add other lenses, external flash is available,4x optical zoom.
Weaknesses: The big LCD is low resolution, but this is not that important, the add on flash is proprietary, you can't use just any external flash, no other weakneses that I noticed.
Overall: I purchased the Canon A540 in December 2006 after extensive research in the Web, I liked all the reviews I read about it and I was not disappointed when I started using it. If you decide to buy this camera, you will need to purchase a high speed SD card to be able to realize its full speed potential (I would say at least 60x , 150x even better). Unfortunately I lost the camera on a trip to Boston when it fell under the seat of my rental car after a near collision on the highway when I was on my way back to the airport, I liked the camera so much that I bought another one to replace my lost unit. I highly recommend this camera for a person looking in the under 200 dollar price range.

Strengths: love the pictures
Weaknesses: short battery life
Overall: I contacted Canon thinking I had a defective camera, but from what I've read, it seems to be common. I had purchased the camera for a short trip to San Diego and drove myself crazy on a 4 day trip needing to buy batteries and carry them around with me. It seems the more pictures I took the shorter the batteries lasted. Is that normal? It doesn't seem like it would be worthwhile for me to hold on to this camera if I have to keep buying batteries for it. How reliable is that? I also noticed they sell an optional charger, is that better? Which battery lasts the longest? PLEASE HELP!

Strengths: compact size, intuitive use on basic settings, rechargeable AA batteries
Weaknesses: manual is difficult to decipher, zoom overshoots way fast
Overall: I bought this camera 4 months ago to replace my venerable 2.1MP Olympus D-510 Zoom (which still takes pictures but the LCD won't stay on). The A540 is more compact and a little lighter, making it easy to carry on a purse or larger pocket (not a shirt-pocket, sorry guys). The basic Auto settings are intuitive, but it took me a long time to figure out from the manual that the fill-flash is only available in some settings (the manual does not say which ones). Still, when we needed another camera for our small business, I surveyed the options and ended up with another A540 as best-buy for our needs. It's worth it even if I have to sit down with the manual and burn through a set of those rechargeable batteries just figuring out the settings!
