Canon PowerShot SX110

The PowerShot SX110 IS is equipped with many of the same features as a higher-end camera: An ultra-powerful zoom, eye-popping resolution and advanced picture-improving technology. This compact camera sports a fast, steady 10x optical zoom that keeps up with your most ambitious shooting: No more standing on the sidelines wishing you could get in closer. 9.0 megapixels of resolution give your photography incomparable depth and ensure that any section of any shot can be enlarged and cropped with no loss in quality.

Canon PowerShot SX110 Features:

Exceptional value in a compact ultra-zoom 9.0 Megapixel digital camera.

Zoom in for sharp, steady close-ups with Canon's 10x Optical Zoom lens with Optical Image Stabilizer Technology.

DIGIC III Image Processor with Genuine Canon Face Detection AF/AE/FE/WB sets the focus, exposure, flash and white balance automatically so you always capture the perfect face.

Take your camera everywhere with this new slim design and large, bright 3.0-inch LCD.

AA batteries for power anywhere.

A wide range of shooting modes to capture anything.

Print/Share Button for easy direct printing and downloading, plus ID Photo Print and Movie Print with select PIXMA Photo Printers and SELPHY Compact Photo Printers.

You will be able to pick up Canon PowerShot SX110IS at the end of this month for $299.99 in the US, while those in Europe will have to wait until September, paying a much more expensive €309.

Which camera is better, Canon 950 or Canon SD1100?

So which camera is better, Canon 950 or Canon SD1100?

Answer from byjamesderuvo:
They're both very similar. But for comparison, you may want to check out this resource. It takes pictures with each and you can compare them side by side. But frankly, don't get caught up in the "more megapixels must be better" falacy.


For picture quality, I think there's too much MP in the SD1000 to work with. Let me explain. I came across an interesting article today about how more mega pixels is not necessarily a good thing. According to Image Engineering – a company that does testing of digital cameras for photo magazines in Germany – the quality of digital pictures has steadily decreased since the state of the art was six megapixels back in 2004. And because they don’t have a “dog in this hunt,” they put forth a compelling argument for buying new digital cameras with less mega pixels and not more.

The argument is essentially this: CCD chips on point and shoot cameras a smaller and as such, fitting in more pixels causes them to lose light sensivity. Sure, there’s more data on the chip, but the chip can’t absorb the light data and what it ends up with is a picture that has more noise than image quality. In addition, the more megapixels a camera has, the larger the lens it needs to provide the clarity it deserves and prevent diffraction due to a loss of detail with smaller apertures. But since we’re talking portable point and shoots here, those large lenses simply aren’t being made.

Finally, with larger mega pixels comes longer saving time due to their requires huge storage capacity, or more compression if not storing images in RAW format. The result is a noisier image and a dissatisfied camera user who thirsts for high quality and speed but fell into the trap of "more must mean better."

In the end, relying on a smaller MP that can balance all these needs may indeed be a better answer.

Setting your camera to a lower setting doesn't help either. Essentially, the image is reduced to the set quality after it has been processed by the CCD. As such, the light still goes through those pixels, only that after some basic processing steps pixels "thrown out" to make the image to the desired setting and size. This process is called "Choking" and that will cause Artifacting and noise. Additionlly, you'll also loose details of the recorded image.

Some cameras have written into their firmware a process called "binning," which merges the signals of multiple pixels to make larger pixels. Usually at a 4-1 ration. This will essentially turn a 12-megapixel camera into a 3-megapixel camera. And that gives you the opposite problem of too many pixels on the chip ... you now have too few and as such, will run into artifacting instead of noise.
