fantastic balance of size, speed, photo quality, capabilities, April 3, 2006
***NOTE: Canon has once again upgraded its A-series of compact digital cameras for 2007. I have upgraded to the outstanding A570IS, which adds optical image stabilization, lower noise, and a better LCD. Check out my review of the Canon A570IS***
After many years of fantastic pictures (as long as the subject was stationary!) my trusty Olympus D40-Zoom died - luckily at the end of a vacation. I spent about 30 hours researching a replacement that would satisfy my goals of (a) compact size, (b) standard AA batteries, (c) full manual controls, (d) outstanding image quality, (e) speed, (f) optical viewfinder.
In my opinion, the Canon A540 fits the bill almost perfectly. It's small enough to fit in a coat pocket or small belt case yet uses 2 AA batteries. Overall processing speed is blazingly fast unless you're taking flash pictures (and then you should expect about 4-5 seconds between flashes). Note that flash time is significantly better with rechargeable NiMh batteries than with standard AAs. And, unlike some other cameras I tried, the speed of the user interface (especially during playback) is very fast.
Picture quality in general is excellent, even in night situations. You have the option of ISO 80 - ISO 800 with the latter being noisy but usable. (Would you rather miss a shot completely or have a little noise? How about the ability to take a picture in low lighting without the flash?) And, you have full manual controls, in addition to the 21 predefined scene types. I'm not sold on the usefullness of the Color Swap and Color Accent modes, but the other modes are well thought out.
Perhaps the biggest surprise was the movie mode, which offers up to 30 fps VGA quality 640x480 continuous shooting up to 1GB per clip, to the maximum size of your SD card. This is still no substitute for a high-quality camcorder, but it's a nice option to have in those situations where you just have the camera. (And note that unlike this camera, most camcorders offer some form of image stabilization.) Note that the movie mode on the A540 is significantly more capable than the lower-megapixel twin A530 (which is limited to 2 minute clips at 15fps).
I was close to getting the Canon A700, which uses the same 6MP sensor and user interface but offers a 6x optical zoom instead of a 4x zoom. In the end, after trying both cameras in the store, I settled on the A540. Why? The A700 is ever-so-slightly larger (about 0.25 inches wider and slightly taller), and the more complicated lens takes longer to startup and to zoom. Maybe it was the lighting, but the noise quality on the A700 seemed higher than the A540, although they use the same sensor. Perhaps this has something to do with the different lenses? Finally, the A700 doesn't offer an underwater case which I'd like to have as an option some day.
In summary, Canon A540 Pros:
- very fast startup and shot-to-shot speed (flash not withstanding)
- excellent and speedy auto-focus even in low light (although the AF assist light can slow this down)
- extremely fast user interface and playback performance, even zooming in on photos
- outstanding photo quality, even in relatively low light (good color balance, noise levels at high ISO are acceptable, almost non-existent chromatic aberation)
- 6 megapixel sensor, 4x optical zoom
- ISO 80 to 800 (800 has noticeable noise but still usable)
- surprisingly usable movie mode (unlike the A530, can record up 30fps of continuous video at 1GB sections up to size of the SD card)
- outstanding user interface: options are well laid out and easy to locate, very well thought-out record and playback options
- full manual controls (shutter priority, appeture priority, full manual)
- custom white balance option in addition to presets
- flash adjusts angle based on wide-telephoto zoom
- well built case, very comfortable grip
- uses SD cards (and takes advantage of high-speed SD)
- uses 2 AA batteries
- unbelieveable battery life (approx 350 shots on 2 rechargeable NiMh AA, with the display on)
- supports optional conversion lenses and underwater case
Cons (to me, all very minor):
- screen while large isn't very high res (85k pixels)
- flash recharge time is acceptable but not great (4 - 5sec between pictures using NiMh batteries)
- preview display blanks while flash recharges
- it's possible to insert the SD card upside down and you don't realize until you try to close the cover (would be easy to break the cover if you force this)
- the markings for the battery orientation are difficult to read
- no RAW image support, but you can select from 3 different compression ratios for image quality
- dubious color accent and color swap modes

The newest and best Powershot A in the series!, June 24, 2006
I began, years back, with Canon's Powershot A20 2MP), then promoted myself up to the A70 (3.2MP) about two year ago. Three days ago, I received my newest self-indulgence: the new Powershot A540 (6MP). So far, I have used it to take 40=50 shots, indoors and out, day and night, using both the Automatic and Custom settings. In every instance, I have been more than simply pleased.
The 2 1/2 inch LCD display is a particularly welcome feature for me at nearly age 60 - everything is a LOT easier to see. I bought a 1GB Secure Digital card for it (Canon insists in shipping their cameras with a useless 16MB card) and a set of 2500s (NiMH batteries.)
Compared to the A70, this camera is easy to manage, quite light (requiring only two batteries, not the four needed by earlier models.) A simple delete button also simplifies the immediate dumping of bad shots. The 4X optical zoom is also a welcome change to the older format.
I am purely an amateur photographer.
Other criticisms I have seen re the poor definition on the LCD screen are, I feel, kind of 'nit picking' - looking for something to criticize about a really good camera.
I found this one online for $223. (Shipping included), sold the A70 used through Amazon for $160 in 24 hours - so the upgrade cost me about $60 net. Well worth every penny.
The pictures themselves are clear. The white balance is great and I leave the setting at 1600x1200 - unless I feel I will need a poster size print. This setting allows over 1700 images on the 1GB card!
I think it will do quite nicely.
Light, easy to handle and good quality images. What else could we realistically hope for at this kind of price?
I recommend it heartily.

A wonderful point and shoot camera, July 12, 2006
The short version:
This is a great camera for people who want an easily portable camera that is FAST and takes great pictures out of the box (but has some versatility for those who want to be able to do more).
The long version:
I'm a decidedly novice photographer, although it is something of a running joke in my family about just how many photos I take. I was looking to replace my previous digital camera, which took great pictures of stationary objects but wasn't fast enough to catch the shot I wanted if the subject wasn't holding still-- e.g. kids at play. I've now had this camera for a month and taken approximately 450 photos in various conditions. Some things I've noticed:
1) Battery life: not great, but frankly better than I expected. I'm on the third set of disposable batteries; the set that came with the camera lasted about 100 photos, and I switched out the second set a couple days ago before leaving on a trip-- they weren't "dead" but I figured they were close to the end of their usefulness. Partially charged batteries are most noticable when using the flash, when they can really delay getting that next shot. And it is GREAT to be able to use AA batteries.
2) Red eye: Wow!!! What a dramatic improvement from my old A95! Yes, I still occasionally have to correct red-eye, but far less often. I do have the built in red-eye reduction set to "on"
3) Speed: again, WOW!!! There is virtually no shutter lag-- I press the button, and get the picture I wanted. Ok, I've also learned to partially depress the button to focus the camera and wait for the shot I want-- but even when my subject is in motion and I don't want to pre-focus I can virtually always catch the moment I meant to catch. Assuming I either have fresh batteries or am not using the flash, I can take the next photo just a few heartbeats later-- and I understand that there is a "burst mode" I haven't used which takes 2 photos a second until terminated or out of memory.
4) Ergonomics: There are smaller cameras out there, but this will fit if awkwardly in my pants pocket. It is significantly lighter weight than my old camera. Controls are logical and easy to use; they don't get bumped accidentally but aren't hard to adjust on purpose.
5) Settings: There are a multitude of pre-determined settings on this camera; I've just scratched the surface and have been impressed so far. This lets those of us with skills best described as "push here dummy" get better shots under special circumstances-- on the beach, snow scenes, indoor shots, objects in motion. The manual settings are wasted on me, but I understand they are there, too.
6) Zoom: the 4x optical zoom means is more than you'll find most anywhere else (with a few notible exceptions). This camera also has a on-screen icon that will blink at you if there is camera motion that might compromize your shot. I have noticed that I just plain can't hold the camera still enough at maximal zoom to avoid having this warning flash at me. I haven't noticed that snapshot quality was affected, but I suspect that if you blew it up to 8x10 (or perhaps larger) that you might notice it. It does make me wonder if a 3x zoom would have been adequate for my needs, since the odds of me hauling around and using a tripod are virtually nil. I have the digital zoom turned off on the camera; I figure I can crop if I want to after the fact but am starting with a maximal resolution.
7) Memory: get another card. Period. I have a 1 GB card that I've never come close to filling despite setting photoquality at maximum resolution, but I download frequently and haven't used burst mode or video.
8) Photo quality: Great! I can see the individual water drops glisten in mid-air in the shots of my son splashing my husband, colors are rich and accurate. Some shots, especially if I'm using the "kidsnpets" setting, are a little "soft"-- not quite crisp images, but I only notice this when I really blow the image up on my computer screen and I doubt I'd appreciate it otherwise. I think if you are ordering an 8x10 or smaller you wouldn't recognize it at all.
The one thing I liked better about my old canon A95: The rotating LCD display, which was also a bit more visible in bright light (possibly because I could adjust the angle)
