I bought the camera a year ago and I am very satisfied. This camera I use complementary to my Canon 5D Mk IV.
For a micro four-thirds camera, the E-M1 II is relatively large, but still lighter than a full-frame camera. Ideal for hiking and mountain excursions.
For me, the strengths lie in landscape and wildlife photography.
In landscape photography, I appreciate the High Res mode. However, the images have a certain "softness". Even if you use the "Pro" lenses. Nevertheless, you get more details than when you shoot with the normal 20 megapixels. As a bonus, the hi-res image has less noise and has a noticeably higher dynamic range.
For wild-shoot photography, the smaller sensor is an interesting compromise. The lenses are lighter and shorter. You take this camera with you even on a long hike. The electronic shutter extremely fast (60fps RAW) and even the mechanical shutter more than fast enough for most cases. ProCapture is a fantastic feature. The phase detection auto focus on the sensor clearly distinguishes the E-M II from other micro four-thirds cameras.
Of course, the small sensor of the E-M1 II can not keep up with a full-frame camera. It delivers 20 megapixels on the quarter of the area of a full-frame sensor. This is especially noticeable when it comes to picture noise. 1600 ISO still produces usable pictures, but the noise is already clearly visible.
There are many small and lightweight micro four-thirds lenses. However, this small design also has its physical limits. Not only do you have to multiply the focal length by the crop factor two, but you have to be aware that you have to do this with the aperture as well. The Olympus "Pro" lenses are excellent, but also bigger, heavier and more expensive.
The menu is initially a bit cumbersome and partly based on confusing icons. For example, a heart means "silent" / sets the camera to the electronic shutter.…more
