The micro-single camera is positioned as a cross-border product between a digital SLR camera and a card machine. With its lightweight body, stylish appearance and high image quality, it has become a popular model in the current camera market. In the past, consumers can only choose SLR products when purchasing high-performance cameras. The appearance of micro-singles gives us more choices. How to choose micro-cameras? Which one is cost-effective? The following small series introduces to you:
     After explaining the meaning of the micro-camera, let's talk about a few key points to pay attention to when choosing a camera. The "cmos sensor size" is probably the most important factor. As shown in the figure below, we can simply understand that the larger the size of the sensor, the better the picture quality of the camera. At present, most professional photographers choose a full-frame size SLR or micro-single for photography. Therefore, the full-frame camera is similar to a symbol of identity, and the industry also has the saying that “full-frame is one step in placeâ€. Of course, we only talk about equipment here, not about photography.
     Which one is cost-effective? Currently on the market for the sale of cameras, Sony's micro-single sensor size is mainly APS-C format and full frame. Fuji's camera only has APS-C format. Panasonic's camera is mainly 4/3 (M43) format.
     This makes it easy to see at a glance. If you are pursuing picture quality, it is natural to choose Sony's full-frame micro-single. A7, A7R, A7S, A7II, A7RII, A7SII, prices range from seven to eight thousand to two thousand. A7 is a full-frame micro-single with good balance and very high cost performance. The disadvantage is poor control. A7R is a micro-single that pursues high-quality and high-pixel. A7S is a micro-single that seeks to take pictures under low light. The pixels are low but the high-sensitivity is very good. The A7II is an upgraded version of the A7 that greatly improves handling and is equipped with five-axis anti-shake, which is the best micro-camera currently available for purchase in my eyes. The A7RII is the pinnacle of Sony's micro-single, high-pixel, 4K video, five-axis anti-shake, using almost all of Sony's black technology, of course, the price is also the highest. The A7SII is a camera that pursues extreme dark-light video capture, with unparalleled high-sensitivity and 4K recording, as well as five-axis anti-shake.
     Which one is cost-effective? I believe that everyone knows through the above introduction.
