Do megapixels matter in a DSLR?

When a new camera is released, one of the first features which people point out are the number of megapixels which it has.

There are a ton of cameras out there which crazy megapixel counts. This often makes people feel that the more megapixels they have, the better their images will be.

But do megapixels really matter all that much in a camera?


Why megapixels matter

Having a lot of megapixels in your camera has its advantages. For example, a 42 megapixel camera will give you 100% more detail than a 21 megapixel camera.

This doesn’t really matter for most people who just want to get a good picture. More detail comes in handy for those who want to print their pictures.

This also comes on handy when cropping photos. When you crop a photo, the number of pixels in the image is reduced. this also reduces the overall quality.

But if your camera has a lot of megapixels, you’ll get a lot of detail in your photos even after croping.


Why megapixels don’t matter

Having many megapixels has disadvantage such as…

Less light

Even though the sensor receives the same amount of light as usual, the camera has a harder time distributing the light to all the pixels.

More noise

Due to the number of large number megapixels, each pixel gets less light. This increases the amount of noise when shooting in low light.



When buying a camera, some people feel the need to go for one that has a crazy number of megapixels.

These types of cameras are usually very expensive, and honestly might not be the best pick.

You need to be sure that the camera you are about to buy is the best for what you want to do.
