Sigma SD15 vs YI M1

On this page, we will be reviewing the Sigma SD15 and YI M1, former being a Advanced DSLR while the latter is a Entry-Level Mirrorless by competitors Sigma and YI. There exists a large gap among the resolutions of the SD15 (5MP) and M1 (20MP) and the SD15 (APS-C) and M1 (Four Thirds) provide totally different sensor sizing.

The SD15 was announced 7 years earlier than the M1 and that is a fairly serious difference as far as camera technology is concerned. The two cameras have different body design with the Sigma SD15 being a Mid-size SLR camera and the YI M1 being a Rangefinder-style mirrorless camera.

Before we go right into a detailed comparison, here is a simple highlight of how the SD15 matches up versus the M1 in the way of portability, imaging, features and an overall rating.

Here is a preview of the gallery photos for Sigma SD15 & YI M1. The whole galleries are provided at Sigma SD15 Gallery & YI M1 Gallery.

Quite often, it can be difficult to visualise the contrast in sensor sizing merely by looking through specifications. The photograph underneath might provide you a greater sense of the sensor dimensions in the SD15 and M1.

To sum up, each of the cameras have different megapixel count and different sensor sizing. The SD15 having a bigger sensor will make achieving shallow depth of field easier and the YI M1 will provide you with extra detail with its extra 15MP. Higher resolution will help you crop photographs a bit more aggressively. The older SD15 will be disadvantaged in sensor tech.
