Point and shoot cameras are okay, but they really don’t take the kind of awesome photos you can get from dSLR cameras with interchangeable lenses.
At the same time, those cameras are so huge that you really have to want to take one with you. They have not only huge lenses, but a huge camera body. Even though the camera itself has moved to the digital age, the mirror has stayed as if we just slapped some electronic sensors on the back of the same camera design we’ve been using for decades. But now there’s another choice.
Let me explain a little. On dSLR cameras, the d stands for digital, and the SLR stands for Single-Lens Reflex. The camera has a series of mirrors that lets you see through the lens when you look through the viewfinder, and the mirrors go up out of the way when you snap a shot to let the camera sensors record the image. You can also swap out lenses for a variety of shots or effects.
That has a couple of inconvenient side effects. It means your camera body has to be big and bulky enough to house those mirrors, and it means that although you can change lenses, you can’t always change them between brands of camera body, since some of them would require the lens to be closer to the camera in order to focus.
Enter the mirrorless cameras.
