Many of the leaks and rumors of the Galaxy A51 point at a device with a quad-camera setup. If the leaks are anything to go by, the device will be Samsung’s cheapest smartphone with a quad-rear camera setup.
Last year, the Galaxy A9 (2018) became Samsung’s first Galaxy phone with a quad-camera setup. The camera setup on the A51 is, however, quite different from that on the A9.
The Samsung Galaxy A51 will feature a 5MP macro lens. Like telephoto lenses, macro lenses let you get close to a subject. However, macro lenses have a much shorter minimum focusing distance. This means that macro lenses allow you to get closer to the subject than telephoto lenses without losing focus.
Macro lenses are excellent for taking photos of flowers or insects. With macro lenses, because of the shorter focusing distance, you have to physically move closer to the subject. This is one area in which telephoto lenses probably have the upper hand. However, macro lenses are cheaper alternatives to telephoto lenses for smartphones. This may be why Samsung is choosing to use a macro camera on the Galaxy A51.
The Galaxy A 51’s other three rear cameras are a 48MP primary shooter, a 12MP ultra-wide camera, and a 5MP depth sensor. The device is equipped with a 32MP front camera in a punch hole on the display.
