THE FUTURE MEGAPIXEL WAR
Nikon showed that you can load 36 million pixels on a full-frame digital sensor, pull o image quality and save lots of cash by not having to buy a medium format digital back. Thanks to that, and the company’s insistence on 24MP as the baseline for its latest generation of DLSR cameras, it’s likely the megapixel war will keep on escalating as companies strive to outdo one another on the market shelves.
While more megapixels are good, they’re not always better – if the camera’s sensor technology and image processor can’t handle the input, you risk losing image quality with the smaller photosites. And the more megapixels your camera has, the better your glass needs to be to properly make use of them, and the better your shooting technique needs to be as small mistakes can and will be
So the key takeaway here is not to be with megapixel numbers, no matter how high they’re likely to become in the near future. While more can be better, it isn’t always the case, and even then, the increased megapixel count always comes with a price. Know the between how many megapixels you want versus what you need by knowing where your images will nally end up. The numbers don’t always tell the complete story, as a doubling of megapixel count doesn’t equal to a doubling of resolution. Buy smart, shoot straight.
