Sony A9 II vs YI M1

Below is a extensive assessment of the Sony A9 II versus YI M1, one being a Pro Mirrorless and the other is a Entry-Level Mirrorless by competitors Sony and YI. The sensor resolution of the A9 II (24MP) and the M1 (20MP) is very well matched but the A9 II (Full frame) and M1 (Four Thirds) boast different sensor dimensions.

The A9 II was brought out 3 years later than the M1 and that is quite a big gap as far as tech is concerned. Both cameras feature different body design with the Sony A9 II being a SLR-style mirrorless camera and the YI M1 being a Rangefinder-style mirrorless camera.

Before going straight to a step-by-step comparison, here is a quick highlight of how the A9 II matches up against the M1 with respect to portability, imaging, features and an overall grade.

Here is a sample of the gallery pics for Sony Alpha A9 Mark II and YI M1. The entire galleries are viewable at Sony A9 II Gallery and YI M1 Gallery.

In many cases, it can be hard to visualize the contrast between sensor measurements merely by looking at technical specs. The graphic underneath may offer you a clearer sense of the sensor sizes in the A9 II and M1.

As you have seen, both the cameras feature different megapixel count and different sensor measurements. The A9 II featuring a larger sensor is going to make getting shallow depth of field simpler and the Sony A9 II will resolve more detail having its extra 4MP. Greater resolution will also enable you to crop photos way more aggressively. The younger A9 II should have a benefit in sensor technology.
