Excerpt: I have the A640-- bought it back around Christmas and started using it in the spring. It has many of the same features as the 540 but has 10 mp. I used it as a hiking and climbing camera instead of my SLR this summer and got great shots that I think are comparable to what most people get with an SLR. I missed the control that the SLR gives, and I sometimes wanted a wider angle and a lens hood, but I have no real complaints.
Excerpt: Canon Powershot A540 adds Shutter and Aperture Priority Modes to the old Canon A530 as well as 6MP instead of 5MP, and continues featuring the 4x optical zoom. Also, it enlarges the LCD screen and a 16:9 widescreen resolution option. Not only that Iâ€™m happy to find a compact digital camera with manual functions and controls, but Iâ€™m also happy to see it has a quite good optical viewfinder that can be used when the sign low battery appears; and the possibility to...
Excerpt: The Canon PowerShot A540 is an entry to mid level, sub-$300 digital camera that offers six megapixel image resolution and a 4X optical zoom lens. The camera is a bit larger than the credit card sized cameras that have become popular, and is powered by standard double AA batteries rather than a proprietary unit from the company. This is a definite advantage, especially for those who are looking for a camera that can be powered by batteries found at the corner drug store.
Conclusion: The very affordable Canon PowerShot A540 offers 6 megapixels, a 2.5 inch LCD and a 4X zoom lens. The A540 offers full manual controls too, in addition to auto and scene modes - making it a good choice for most people. The PowerShot A540 also has good battery life though competition is getting better. The LCD is at its largest size as well (for an entry-level camera), being a good 2.5 inches with nice visibility. Despite that, the resolution is not at all high.
Pros: Nice 4x zoom lens, Good (not excellent) battery life, Large LCD with good visibility, Full manual controls with many accessories, Unlimited, fast continuous shooting, Fast performance, VGA 30 FPS movie mode, Produces good photos, acceptable till ISO 400, Affordable
Cons: Low LCD resolution, Faster shutter speeds restricted to small apertures, Overall performance could be faster and better; especially autofocus, Movies limited to 1 GB; around 8 or 9 minutes at the highest settings, Redeye and ISO 800 needs some cleanup
Excerpt: The Canon PowerShot A540 ($300) is a midrange digital camera that offers a 6 Megapixel CCD, 4X optical zoom (instead of the usual 3X), large 2.5" LCD display, full manual controls, and a VGA movie mode. The A540, along with its 5 Megapixel sibling, the A530, replace Canon's extremely popular A510 and A520 models from last year. Both cameras use Canon's DIGIC II image processor.
Pros: Very good photo quality; ISO 200 and 400 settings are usable for small prints, 4X optical zoom gives you a bit more telephoto power than most entry-level cameras, Large 2.5" LCD display is usable in low light (though see issues below), Full manual controls, unusual for an entry-level camera, Snappy performance, AF-assist lamp, good low light focusing, Very good movie and continuous shooting modes (though see issue below), Support for add-on lenses, external slave flas...
Cons: Poor LCD resolution, Some redeye, Can only record about 8 minutes of VGA video due to 1GB file size limit, Plastic tripod mount, No rechargeable batteries bundled; tiny memory card included

Continue on to Features & Controls Powershot A540 Specifications Camera Effective Pixels Approx. 6.0 million Image Sensor 1/2.5-inch CCD (Total number of pixels: Approx. 6.2 million) Lens 5.8 (W) - 23.2 (T)mm (35mm film equivalent: 35 - 140mm) f/2.6 (W) - f/5.5 (T) Digital Zoom Approx.
Conclusion: It is becoming harder to find this type of digital camera. It is therefore a good job the Canon Powershot A540 is up to the mark. I was impressed by the picture quality both indoors and outside. If you would like a digital camera with manual controls and not break the bank then this camera is well worth looking at.
Pros: Manual controls, Picture quality, Value for money
