What is a full-frame camera? What is a rangefinder camera?

1. Full-frame camera refers to the size of the photosensitive area of ??the imaging element of a digital camera. The size of the photosensitive element is divided into large format, medium format, full frame and small format. The size of the full-frame photosensitive element is equal to the size of ordinary film. , the size is: 36mm When using the camera Canon 600D, due to the smaller size of the sensor, the focal length of the same lens is also extended accordingly, about 1.5 times, which is equivalent to a focal length of 36-105mm. Therefore, a full-frame digital camera not only allows the lens to be used at equal focal lengths, but also has a very high image quality. Another: People have less exposure to large and medium format cameras. Here is a brief introduction to Pentax’s medium format camera 645D. The effective pixels of this camera are: 40 million pixels. The sensor size exceeds the full frame: 44×33mm, and the imaging quality is extremely high. , a machine that belongs to the commercial photography category.

2. A rangefinder camera has an optical viewfinder on the body specifically for viewing. The image when taking a photo is referenced through this viewfinder, so it is commonly known as a rangefinder camera. Rangefinder cameras include Canon's G12, Fuji X100, and Nikon's P7000. Of course, rangefinders generally fall into the small format category.
