Don’t Believe The Marketing Spin About Megapixels: Writer Rob Sheppard recently posted an article in PCPhoto titled, “Those Lying, Cheating Megapixels” where he cautions camera purchasers to consider other ‘quality determining’ factors. Marketers are determined to convinced you that megapixels ARE the determining factor while Mr. Sheppard point out that you might be disappointed of you follow the suggestions of salespeople.

Those Lying, Cheating Megapixels
I’ve overheard salespeople at retailers comment on how much better a certain camera is because of the megapixels. Round-up articles about digital cameras in newspapers tend to overemphasize megapixel numbers. Over the years, manufacturers and retailers have hyped megapixels as a critical factor in buying a digital camera. No wonder this is so confusing!
A few years ago, megapixels were a defining characteristic of a digital camera, especially when the first 1-megapixel cameras came out. Finally, true photo quality appeared possible. Then 2- and 3-megapixel sensors upped the quality so that excellent 4×6, 5×7 and 8×10 prints could be made. Advertising the benefits of more megapixels made sense.
Now with 4, 6 and 8 megapixels common, you no longer can compare cameras strictly on megapixels. Each of those sizes is capable of superb, highest-quality prints at 11×14 inches and larger. The more megapixels, the bigger you can make a print, but unless you’re a pro, there’s more difference in many other camera features than megapixels for the average photographer. But like Tim Allen and “Tool Time,” big sometimes overpowers reason.
All megapixels aren’t created equal, either. Tiny photosites on a 5-megapixel cell phone camera have no hope of matching the color, tone, low noise and other characteristics of a 4-megapixel pro camera, for example (let alone getting a high-quality lens into a small cell phone). For true digital cameras, once you have enough megapixels, other features—from lens type and quality to lag time to exposure systems to ISO settings and noise—become more important.
