"The Nikon D40x has a sensor resolution of 10.2 megapixels, and offers ISO sensitivity ranging from 100 to 1,600, with the ability to extend this to ISO 3,200 using the Hi-1 setting. Even though the sensor resolution has been increased from six megapixels in the original D40 model, the ten megapixel D40x offers a faster burst mode of three frames per second. The D40x retains the same compact size, portability and ease-of-use as its popular sibling, the D40.


Unlike a move from 8 megapixels to 10 megapixels, the jump from 6 to 10 megapixels is indeed a large one. Enlarge both images to 100 percent onscreen, and you can see just how much larger objects are. It turns out this is an excellent way to gauge how much more detail you're getting. Your screen resolves at only one resolution, so if you set both images to match, you can see how much detail you have in each image. I've done it for you to the right. The top image is from the D40, the bottom from the D40x. If you're not going to be doing a lot of cropping or enlarging beyond 11x14, you won't notice much difference between the D40 and D40x except the average file size. I would be happy with either, but our tests do show that the D40x has greater dynamic range than any camera we've tested. More on that later in this report, and on the Imatest page."
