Megapixels indicate how much detail an image will have. Generally, the more megapixels in an image, the larger you can print a photo while retaining its sharpness.
Conversely, lower megapixels tend to perform better in low light situations. This is because the fewer pixels are physically larger individually and will create less digital noise in the image!
This means that a high Megapixel camera is not necessarily the best option for everybody or every application. Spend some time considering and thinking about the images you plan to create then speak to one of our sales associates or product experts to help you make the right decision!
