I recently chatted with Dan Kesselring from Panasonic to get some tips on how to buy a digital camera for my column in 24hrs.
Megapixel is where a lot of people get confused. It simply refers to the dots in the image.
If you have a 7 megapixel camera vs one with 10, you’re really only going to see the difference if you’re using the camera to make very large prints, say beyond 19×13. Dan says really 5 megapixels is enough for most of us who are just printing 4×6 or archiving family memories
When it comes to specific features, “image stabilization should always be top of mind,” says Kesselring. “Its almost become a generic term, but there are different types and optical is providing the best form of stabilization.” [link]
A test done by a German company is now coming out with similar information. More megapixels does not equal more better.
The study actually finds that picture quality over the last 3 years has actually decreased as megapixels have increased.
But why? Well, compact cameras are supposed to be small and reasonably priced. Therefore small image sensors, e.g. format 7.5 x 9.4 mm or 5.4 x 6.8 mm, are built into the cameras. To increase the pixel count, the sensor has to be divided into smaller and smaller pixels.
The result is a decrease in sensitivity of the camera and an increase in noise because the amount of light collected by a single pixel is smaller. [link]
So as the CCD sensors have to stay small for the point and shoot, they have a harder time getting the larger amounts of data processed properly. The study found the optimum relationship between CCD and MP comes in at 6 Megapixels.
That’s got to be the reason so many more people are stepping up to Digital SLR. Me? I’m not quite ready, so I picked up the Panasonic FZ-18 instead. It’s $500 list price, but I managed to grab it on sale for $250 at Amazon.com
Check out some of the pictures I’ve been able to grab with it:

Since the FZ18 is kind of a “hybrid” between a DSLR and a point and shoot, it’s offering me the chance to just grab it and take a picture, or work with the settings for something more artistic.
For that sunset shot, I just pointed and clicked. Nice.

Buzz, I have a Nikon Coolpix L3 5.1 megapixels.
Nice pictures from your camera!!
Thanks for the info about megapixels.
Happy New Year,
Bruce
Definitely right about how many megapixels you need — too many people are falling for the line that they need a 10 megapixel digital camera, and then they’re only using the images for their blog or a webpage. For that, you can get away with a TWO megapixel camera, even.
I’ve just picked up a new SLR myself, but that’s because I love to play around with exposure and focus, and there are very few point and shoot models that make that even halfway possible without pushing a zillion buttons. (And of course I swap lenses regularly for specialty shooting too, so that’s another key point for moving to SLR.)
