Sensor Properties | |
Also M1 has a Four Thirds CMOS sensor with size of 17 x 13 mm² (0.68″ x 0.51″). Picture of M1’s sensor compared to popular format. The 1-Euro coin has a diameter of 23.25mm. The M1’s sensor has resolution of 20 megapixel. The YI supports taking images in RAW. RAW images are stored as they come from the sensor, without any in-camera processing or sharpening. Converting to JPEG or other formats takes place on the computer, using software like Adobe Lightroom or YI’s RAW converter. This involves one extra processing step but almost always results in superior image quality. Some filters, like converting to monochrome (black and white) will only yield decent results when used with RAW images. The M1 does not have a mechanism for automatic sensor cleaning. Dust that collects on the sensor has to be removed with a blower or brush. |

Auto Focus Properties | |
The M1’s auto focus processor uses 81 AF points (or sensors). A basic rule of thumb says that the more AF points you have, the better. More AF points mean a better chance to have a point at the location of interest in a scene, a big plus in challenging situations (e.g. when panning the camera). Manual focus is also possible with the YI, a plus in tricky situations or for some creative freedom. |

Display Specs | |
The M1 features a monitor with a diagonal of 76.00mm (3.0 in.) and a resolution of c. 1.04 megapixel. That’s about average. Unfortunately, the M1’s monitor is not articulated. That can make it tricky to frame your subject in some situations, e.g. when taking selfies. The M1’s monitor can work as a touch screen, just like a smartphone. That can be very useful, for example to pick AF points, but keep in mind that touch screens usually don’t work when wearing gloves. Display characteristics at a glance: |
