Thorough explanation of the appeal of the compact and lightweight mirrorless “Micro Four Thirds”. Introducing carefully selected 4 models of interest!

Mirrorless cameras aren’t just full size! The camera market for professionals and high amateurs may be exaggerated to say “full size whether you look right or left”, but in the last few years, the share of full size mirrorless cameras has increased at a stretch, and the line Now located in the center of the up. Certainly, full-size mirrorless cameras are attractive at a high level of image quality and performance. But each of the other categories of cameras also has a unique appeal. In particular, the mirrorless camera of the Micro Four Thirds system standard (hereinafter referred to as “Micro Four Thirds”) is full of the appeal of “taking pictures more lightly”, which is important for enjoying shooting. In this special feature, I will explain five attractions of OM Digital Solutions and Panasonic’s Micro Four Thirds Mirrorless.

Attractive 1 As a system, it is compact, lightweight, and has excellent mobility.
Micro Four Thirds is a standard that uses a 4 / 3-inch (17.4 x 13.0 mm) image sensor on the premise that the camera is structurally mirrorless. Compared to the full size (about 36.0 x 24.0 mm, depending on the manufacturer and camera) and APS-C (about 23.5 x 15.6 mm, depending on the manufacturer and camera), the size of the image sensor is smaller, so the camera body is Its major feature is its small size and light weight.
How small and lightweight the Micro Four Thirds mirrorless camera is depends on the model, but it is easier to understand than a full-size camera of the same class. For example, when comparing the flagship model “OM-1” of “OM SYSTEM” of OM Digital Solutions and the high-end model “EOS R5” of Canon’s full-size mirrorless, “OM-1” is one size smaller. , The weight at the time of shooting is lighter than 100g.

OM-1
size: Approximately 134.8 (width) x 91.6 (height) x 72.7 (depth) mm
Weight: Approximately 599 g (including battery and memory card, without eyecup)

EOS R5
Size: Approximately 138.5 (width) x 97.5 (height) x 88.0 (depth) mm
Weight: Approximately 738g (including battery and memory card)

At the same time, Micro Four Thirds is a point that I want to keep in mind that the lens is small and lightweight. Compared with lenses that cover the same angle of view, the one for Micro Four Thirds is one size smaller than the one for full size. Not only is the burden of shooting less burdensome, but the fact that you can fit multiple lenses in a smaller bag is especially useful for long-distance shooting such as landscape shooting.
Charm 2 Strong in telephoto shooting
The image sensor of Micro Four Thirds is about the size of a lid compared to the full size, and about one size smaller than the APS-C. Details of the image quality will be summarized later, but basically, if the size of the image sensor is small, there are many disadvantages in terms of image quality.

However, there is also the merit that the image sensor is small. It is strong in telephoto shooting. The image sensor of Micro Four Thirds has half the length of the diagonal line compared to the 35mm format, and the angle of view converted to the 35mm format is equivalent to twice the focal length of the lens. With a focal length of 100 mm, an angle of view equivalent to 200 mm can be obtained.
Micro Four Thirds mirrorless is a very easy-to-use system for shooting animals, birds, sports, etc., which is mainly used in the telephoto range and super-telephoto range. In particular, when shooting animals and birds, which often shoot distant subjects, the narrower the angle of view, the better. In such a case, it will be extremely powerful.

Charm 3 Image quality with excellent resolution
Some people may have the image of a Micro Four Thirds mirrorless camera that “the image sensor is small, so the image quality is not as high as full size or APS-C.” Certainly, compared to full-frame and APS-C, there are some points that are inferior in terms of the size of the image sensor such as dynamic range and high-sensitivity noise. As for the amount of blur, when compared with the same angle of view and the same aperture value, Micro Four Thirds is two steps less than the full size and one step less than APS-C. It is true that the amount of simple blur is not as good as full size or APS-C.

However, when I actually shoot with the Micro Four Thirds mirrorless camera, I can see that the picture quality is higher than I expected. Although the performance of the lens may be high as a whole, it has excellent resolution and more uniform image quality can be obtained over the entire screen. As for the dynamic range, there is no problem in practical use unless you record in RAW and edit the image to change the brightness extremely during development. Of course, if you compare strictly, there is no doubt that the full size and APS-C are more advantageous, but there is no such thing as “the image quality is not good because it is Micro Four Thirds”.

Also, the fact that the amount of blur is small is an advantage if you change your perspective. You can get a sufficient depth of field without squeezing too much, so it should be useful for landscape photography. In addition, the fact that there is no need to squeeze has the advantage that it is easy to increase the shutter speed even in dimly lit scenes. The small size of the image sensor cannot be said to be a demerit.
Charm 4 High level of continuous shooting, AF, and movie shooting functions
The Micro Four Thirds mirrorless camera is also attractive because it has a full range of shooting performance and functions. Below is a summary of the features of continuous shooting performance, AF, image stabilization, and video recording functions.
